Known limitations in IBM Business Automation Manager Open Editions 8.0.0

This section lists known limitations with IBM Business Automation Manager Open Editions 8.0.0.

Process Designer

The JavaScript language in an On Entry Action property produces an error after changing a node to multiple instances [RHPAM-3409]

Issue: When the language of the On Entry Action property is set to JavaScript and you change the node to Multiple Instance, you receive a system error.

Steps to reproduce:

Create a new business process.
Create a user task and set it to the Multiple Instance property.
Enter any string to On Entry Action or On Exit Action.
Select the JavaScript language.
Select the Multiple Instance check box.

Actual result: You receive a system error.

Expected result: You do not receive an error either in the UI or in the server log file.

Workaround: None.

customCaseRoles metadata attribute is not added [RHPAM-4410]

Issue: It is not possible to add a new customCaseRoles metadata attribute in a case process definition.

Steps to reproduce:

Create a case project.
Create a case definition.
Open Case Management in the Properties panel and add a new case role as owner:1.
Save, close, and reopen the case.
In the Properties panel, check the Metadata Attributes under the Advanced section.

Actual result: The Metadata Attributes section is empty.

Expected result: The Metadata Attributes section contains the customCaseRoles:owner:1.

Workaround: None.

DataObject from canvas is missing in assignments when the case file variable is present [RHPAM-4420]

Issue: The DataObject from the canvas is missing in assignments when the case file variable is present. This applies to both top-level nodes as well as nodes placed in sub-processes.

Steps to reproduce:

Create a case project.
Create a case definition.
Add a case file variable to the process.
Create a DataObject on the canvas.
Create a node with assignments on the canvas or in the sub-process.
Activate the node that has the assignments, open the assignments, and click Source/Target.

Actual result: The DataObject is missing from the listed items.

Expected result: Both the case file variable as well as the DataObject from the canvas is present in the listed items.

Workaround: None.

Custom data object in multiple variables causes error in case project [RHPAM-4422]

Issue: When you create a custom data object in multiple variables, you receive an error in a case project.

Steps to reproduce:

Create a case project.
Create a case definition.
Create a custom data object in the same project.
Add a process variable and a case file variable with the same CustomDataObject type.
Create a multiple instance node or data object on the canvas.
If you set a multiple instance node, set the MI Collection input/output and try to change Data Input/Output type.
If you set a data object, try to change the data type.

Actual result: You receive an error.

Expected result: No errors occur.

Workaround: None.

Process engine

When you abort a process instance, the timer is not deleted [RHPAM-4380]

Issue: Aborting a process instance with an active timer does not delete the timer. The timer then fires at the defined trigger date, which is silently dismissed by the system, so this is not a functional problem. However, it populates the EJB timer subsystem with orphaned timers, especially if the timers are long-running and the number of aborted process instances is high.

Workaround: None.

When you use Spring Boot, the UserGroupCallback implementation is not injected into KIE Server [RHPAM-4281]

Issue: When you are using an engine embedded in a KIE Server packaged as a Spring Boot application, the bean defined as userGroupCallback is not injected into the engine. Then, when you try to call some of the rest endpoints fetching some tasks based on the user or groups assigned to them (such as potOwner, stakeHolders, businessAdmin, and so on) they do not work as expected because the UserGroupCallback implementation used in the engine is different from the one defined at the Spring boot application level. Note that this only applies to cases and not to processes.

Steps to reproduce:

Start KIE Server as a Spring Boot app with a default identity provider and a UserGroupCallback implementation.
Try to fetch some tasks assigned to a group by using some rest endpoints such as potOwner, stakeHolders, or businessAdmins.

Workaround: None.

Kafka-clients contain misalignment with any supported AMQ Streams version [RHPAM-4417]

Issue: Kafka dependencies for the community are not aligned with IBM Business Automation Manager Open Editions 8.0. The current Kafka community version is 2.8.0 and it must be aligned with the version used by AMQ Streams 2.1.0 which is 3.1.0 for the community.

Workaround: None.

Spring Boot

Wrong managed version of Spring Boot dependencies [RHPAM-4413]

Issue: The Spring Boot version (2.6.6) in the Maven repository is not certified by Red Hat yet. Therefore, you will receive a mismatch for the Narayana starter in productized binaries.

Workaround: In your pom.xml file, define the following properties to override the current versions:

<version.org.springframework.boot>2.5.12</version.org.springframework.boot>
<version.me.snowdrop.narayana>2.6.3.redhat-00001</version.me.snowdrop.narayana>

Red Hat build of Kogito

Red Hat build of Kogito is aligned with a non-supported Spring Boot version [RHPAM-4419]

Issue: Red Hat build of Kogito Spring Boot versions are managed in the kogito-spring-boot-bom file, which imports dependency management from the org.springframework.boot:spring-boot-dependencies BOM. The currently aligned version is 2.6.6, which does not map to any Red Hat supported versions. The latest supported version is 2.5.12. You must override dependency management with a BOM aligning to the Red Hat supported version which is 2.5.12.

Workaround:

To maintain the order of the imported BOM files, first include the Spring Boot BOM and then include the Red Hat build of Kogito specific BOM file:

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>dev.snowdrop</groupId>
            <artifactId>snowdrop-dependencies</artifactId>
            <version>2.5.12.Final-redhat-00001</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
        <dependency>
            <groupId>org.kie.kogito</groupId>
            <artifactId>kogito-spring-boot-bom</artifactId>
            <version>1.13.2.redhat-00002</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

Align the version of spring-boot-maven-plugin to the same version in your project build configuration file:

<plugins>
      <plugin>
        <groupId>org.kie.kogito</groupId>
        <artifactId>kogito-maven-plugin</artifactId>
        <version>1.13.2.redhat-00002</version>
        <extensions>true</extensions>
      </plugin>
      <plugin>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-maven-plugin</artifactId>
        <version>2.5.12</version>
        <executions>
          <execution>
            <goals>
              <goal>repackage</goal>
            </goals>
          </execution>
        </executions>
      </plugin>
    </plugins>

Red Hat build of Kogito on Spring Boot leads to misalignment of Kafka-clients version [RHPAM-4418]

Issue: The Kafka-clients dependency version for Red Hat build of Kogito Spring Boot is by default managed by the org.springframework.boot:spring-boot-dependencies BOM. Depending on which Spring Boot version is used, users might end up with an unsupported or vulnerable version of Kafka-clients. You must override the default dependency in your kogito-spring-boot-bom to make sure you have the expected Kafka-clients version.

Workaround: In your projects, define dependencyManagement explicitly for org.apache.kafka:kafka-clients dependency to use the version released by AMQ Streams.

Known limitations in IBM Business Automation Manager Open Editions 8.0.1

This section lists known limitations with IBM Business Automation Manager Open Editions 8.0.1.

Note	Review the information on the IBM Business Automation Manager Open Editions 8.0 known limitations page for limitations identified after release.

Business Central

Unable to deploy Business Central using JDK version 11.0.16 [RHPAM-4497]

Issue: It is not possible to deploy Business Central if your installation uses JDK version 11.0.16.

Actual result: Business Central does not deploy when launched.

Expected result: Business Central deploys successfully.

Workaround: Use a previous JDK version such as 11.0.5 or earlier.

Form Modeler

Date type process variable is empty when the process is started using Business Central form with the showTime set to false [RHPAM-4514]

Issue: When you use the default form rendering in Business Central and the process variable field has showTime=false, the started process instance shows that the variable is empty. The affected types are java.time.LocalDateTime, java.time.LocalDate, java.time.LocalTime, and java.util.Date.

Steps to reproduce:

Define the process variable with a specific type.
Generate a form.
Open a form and set showTime=false for a specified field.
Deploy the project.
Open the process form.
Specify the value in the process form.
Check the process instance variables. The value for the specified variable is empty.

Workaround: None.

Form in KIE Server with a java.util.Date field does not allow the time to be inserted [RHPAM-4513]

Issue: When a process has a variable of the type java.util.Date and the value of the showTime attribute is true, in the generated form the process does not allow the time to be inserted. The Date variable shows all zeros in the time part of the data type.

Workaround: None.

Installer

The installer contains the option to enable Business Optimizer support [RHPAM-4555]

Issue: The IBM Business Automation Manager Open Editions installer contains an option for Business Optimizer support.

Steps to reproduce:

Download the bamoe-installer-8.0.1.jar file.
Run java -jar bamoe-installer-8.0.1.jar.
On the Component Installation screen, select Use Custom Configuration for Server Configuration.

Actual result: On the KIE Server Properties Configuration screen, the Enable Business Optimizer support option is present.

Expected result: On the KIE Server Properties Configuration screen, the Enable Business Optimizer support option is not present.

Workaround: None.

Process Designer

BPMN2 files in XML editor have a Properties panel that contains data from other processes [RHPAM-4468]

Issue: If two processes are open, where one process is open in the XML editor (a legacy process with the BPMN2 extension) and one process is open in the new process designer, the properties in the Properties panel, as well as the diagram in the Explore Diagram window from the new process designer, are shown in the XML editor of the other process. The XML editor should not have any Properties or Diagram panel.

Steps to reproduce:

Open any new process designer process.
Do not close the process.
Open the legacy process, for example legacy.bpmn2, in the XML editor.
Open the Properties panel.

Actual result: The Properties and Explore diagram from a new process designer process are shown in the XML editor panel.

Expected result: No Properties or Explore diagram panels are present in the XML editor.

Workaround: None.

Custom data object in multiple variables causes an error in a case project [RHPAM-4422]

Issue: A custom data object in multiple variables causes an error in a case project. You receive a UI exception with the following error:

Uncaught exception: Exception caught: Duplicate value: CustomDataObject [com.myspace.caseproject] Caused by: Duplicate value: CustomDataObject [com.myspace.caseproject]

Steps to reproduce:

Create a case definition in a case project.
Create a custom data object in the same project.
Add a procVar process variable and caseVar case file variable with the same CustomDataObject type.
Save the changes.
Create a multiple instance node or a Data Object on the canvas.
In the multiple instance node, set MI Collection input/output and try to change the Data Input/Output type.
In the Data Object on the canvas, try to change the data type.

Actual result:

On a Chrome browser: It is not possible to set the type with the first click. The custom type is chosen.
On a Firefox browser: An unexpected error occurs.

Expected result: It is possible to set the type correcty. No errors occur.

Workaround: None.

Red Hat Fuse integration

Optaplanner dependencies were not removed from features files [RHPAM-4545]

Issue: OptaPlanner JAR files are still referenced as dependencies in Fuse features files, even though OptaPlanner is no longer available. If you try to install kie-server-client or kie-camel by feature file in Fuse, the installation fails because the dependencies do not exist.

Workaround: Instead of using the Karaf OSGI feature files for IBM Business Automation Manager Open Editions and Fuse integration, directly communicate with Kie Server services with Rest calls. Note that OSGI integration is deprecated and therefore not recommended.

Migration

Wrong SQL Statements in Upgrade Script to BAMOE 8.0.1 [RHPAM-4540]

Issue: A merge for the fix to RHPAM-4540 was performed in the wrong order. This caused the wrong SQL statements to be added to the upgrade scripts for the following databases:

Oracle
MS SQL Server
Postgres
Postgres Plus/EDB
Sybase

Note	This issue only affects the upgrade scripts. You can use the scripts located in the `ddl-scripts` folder to perform a new installation.

Workaround: To upgrade, use the corresponding DDL scripts located at https://github.com/kiegroup/jbpm/tree/7.67.x/jbpm-db-scripts/src/main/resources/db/upgrade-scripts (scripts rhpam-7.13-to-7.13.1.sql). These upgrade scripts resolve this issue as well as the issue described in RHPAM-4253.

Red Hat build of OptaPlanner

kie-bom contains OptaPlanner dependencies [RHPAM-4556]

Issue: The IBM Business Automation Manager Open Editions org.kie-kie-parent-7.67.2.Final-8.0.1/kie-bom/pom.xml sources file contains dependency management for the following components:

kie-server-services-optaplanner
kie-server-rest-optaplanner
kie-server-spring-boot-starter-optaplanner

Workaround: None.

Archtype with appType=planner in kie-archetypes [RHPAM-4557]

Issue: The org.kie-kie-api-parent-7.67.2.Final-8.0.1/kie-archetypes/kie-service-spring-boot-archetype/src/main/resources/META-INF/archetype-post-generate.groovy file contains <artifactId>kie-server-spring-boot-starter-optaplanner</artifactId> that will generate a project with a Red Hat build of OptaPlanner Spring Boot starter.

Actual result: If you try to compile the OptaPlanner Spring Boot starter, it will fail because there are no OptaPlanner artifacts.

Expected result: The org.kie-kie-api-parent-7.67.2.Final-8.0.1/kie-archetypes/kie-service-spring-boot-archetype/src/main/resources/META-INF/archetype-post-generate.groovy file should not contain <artifactId>kie-server-spring-boot-starter-optaplanner</artifactId>.

Workaround: Do not compile the Red Hat build of OptaPlanner Spring Boot starter.

Red Hat OpenShift Container Platform

PostgreSQL 13 Pod won’t start because of an incompatible data dirctory [RHPAM-4464]

Issue: When you start a PostgreSQL pod after you upgrade the operator, the pod fails to start and you receive the following message:

Incompatible data directory. This container image provides PostgreSQL '13', but data directory is of version '10'. This image supports automatic data directory upgrade from '12', please carefully consult image documentation about how to use the '$POSTGRESQL_UPGRADE' startup option.

Workaround:
