In workflow processes that implement case activities, you can interact with case operations through the new operations that have been added to the TWProcessInstance JavaScript API.
For more information about the TWProcessInstance JavaScript API, see TWProcessInstance.
  • addCommentToParentActivity
  • addCommentToParentCase
  • completeParentCaseStage
  • createCaseUsingSameCaseType
  • createCaseUsingSpecifiedCaseType
  • createDiscretionaryActivityInParentCase
  • createDiscretionaryActivityInParentCaseWithWorkflowParams
  • createParentCaseDiscretionaryActivityWithProps
  • createSubfolderUnderParentCase
  • getParentActivityPropertyNames
  • getParentActivityPropertyValues
  • getParentCaseCasePropertyNames
  • getParentCaseCasePropertyValues
  • getParentCaseStructure
  • relateParentCase
  • searchParentCaseActivities
  • setParentActivityPropertyValues
  • setParentCaseCasePropertyValues
  • unrelateParentCase

Processes that are running under a case activity can interact with their parent case using the methods provided in the TWProcessInstanceParentCase JavaScript API. For example:

tw.system.currentProcessInstance.parentCase.addCommentToCase("Hello world!", true);

For more information about the TWProcessInstanceParentCase JavaScript API, see TWProcessInstanceParentCase External link opens a new window or tab.

For information about using new or existing processes to implement case activities, see Adding an activity with a new process and Adding an activity with an existing process.

To work with case properties in addition to the operations, you can also use one of the following new services that are available in the Content Management toolkit. For more information, see the documentation provided with the service.
  • ECM Update Content Object Properties Service
  • ECM Get Content Object Property Service
  • ECM Get Content Object Properties Service
  • ECM Update Content Object Property Service

To work with the parent case from your process instance, you can use the parentCaseId and parentCaseServerName properties that are available in the TWProcessInstance object.

Runtime synchronization of content objects

When a workflow process runs from a case activity, the process has access to the case content objects. Any updates to content objects in a workflow process show up synchronously in the case or activity. Similarly, content object updates from within the case or activity are synchronously made available to the workflow process.
