Configuration properties

Set or modify view configuration in the Configuration properties tab.

Table 1. Instance Activities Section Configuration properties
Configuration property	Property variable	Description
Height	`height (Integer)`	The height of the view in pixels. If the list exceeds the specified height, a scroll bar is shown. To show the complete list without a scroll bar, enter 0. Default: When no value is specified, the height of the control is 600 pixels.
Instance ID	`instanceId (String)`	The instance ID filters the list of activities. This property is required. Default: None
Selected category	`selectedCategory (String)`	Displays activities in the selected category. You can bind this property to a selection control, for example, the Category Selection control. Alternatively, you can set it to a static value so that the control always shows the same subset of activities, for example, all activities. Default: The first entry in the list of categories that are defined for the Define selectable categories configuration property. If no selectable categories are defined, ready activities are displayed.
Define selectable categories	`categories (List of String)`	Defines the set of selection categories and the order in which they appear in a user interface. A category represents a subset of activities, for example, ready activities, and its sort criteria. The categories can be a combination of predefined and user-defined categories. Default: `Ready`, `InProgress`, `Completed`, `All`
User-defined categories	`userDefinedCategories (List of ActivityListCategory)`	A list of user-defined categories. The names of these categories must be unique and not one of the predefined category names: `Ready`, `InProgress`, `Completed`, or `All`. Default: None
Generated selection categories	`categoriesSelectionList (List of NameValuePair)`	The subset of the selectable categories that you want to include in the user interface. The list is generated from the value of the Define selectable categories configuration property. It consists of name-value pair objects; the name property is the display name of the category, and the value property is the category value. You can bind this configuration property to a selection view, for example, the Category Selection view to provide tabbed selection categories at the top of the list. Default: `Ready`, `InProgress`, `Completed`, `All`
Text filter	`textFilter (String)`	Filters the activity list by activity name based on the text that is entered by the user. Default: None
Refresh trigger	`refreshTrigger (Boolean)`	Enables the contents of the view to be refreshed. Bind this property to the private variable that is used by Refresh Controller, Refresh Button, or both. When the value of the bound variable changes to `true`, the view is refreshed. After the view is refreshed, the value of the variable returns to `false`. Default: `false` (no refresh pending)
Retrieve activities	`retrieveActivityListService`	The service that retrieves the list of activities. Default: `Default Instance Activities List Service`
Activities	`activities (List of ActivityListItem)`	The list of activities that are displayed. This configuration property is read-only. Default: None
Retrieve details of an activity	`retrieveActivityDetailsService`	The service that retrieves the details of an activity. Default: `Default Activity Details Service`
Execute action on activity	`activityActionService`	The service that executes an action on an activity. Default: `Default Activity Action Service`
Localization Service	`localizationService`	The service that is used to retrieve the globalized strings for use with this view `Dashboards Localized Messages Loader`

Predefined categories

The following table shows how the predefined categories map to activity states.

Table 2. How predefined categories map to activity states
Category	Description
Ready	Shows the activities that can be started. These activities are in either the `READY` state or the `WAITING` state.
In Progress	Shows the activities that are in progress. These activities are in either the `WORKING` state or the `WAITING` state.
Completed	Shows the activities that are in any of the following end states: `COMPLETED`, `FAILED`, or `SKIPPED`.
All	Shows the activities in any of the following states: `READY`, `WAITING`, `WORKING`, `COMPLETED`, `FAILED`, or `SKIPPED`

The predefined categories are implemented with the getPredefinedCategories JavaScript method. To view the implementation, in Process Designer, on the Behavior tab for the view, select Inline JavaScript.

Customizing the Instance Activities List coach view

You can customize the Instance Activities List coach view in the following ways:

Customize the categories that are used for filtering activities by changing the values of the corresponding configuration properties. For more information, see Customizing categories.
Overwrite the default services that are provided by the control.
- Instance Activities List Service: modify the query properties, for example, sortCriteria, filters, includeHidden properties, or modify the query result, for example, to remove available actions
- Activity Details Service: for example, to modify the narrative
- Activity Action Service: for example, to trigger other actions, such as notifications or updating data
Modify resource strings in the Localization Service resource file, for example, to change the labels of the selection categories
Modify the style settings in the .css file

Customizing categories

The categories configuration property determines which categories are displayed for selection by the user. For example, the following code sample illustrates how to exclude the predefined In Progress category.

// Define categories to be available
tw.local.categories = new tw.object.listOf.String();
tw.local.categories[0] = "Ready";
tw.local.categories[1] = "Completed";
tw.local.categories[2] = "All";

Use the ActivityListCategory business object to define the variables that represent user-defined categories. You can then use the userDefinedCategories configuration property to add new categories or replace predefined categories with user-defined categories. For example, the following code sample illustrates how to replace the predefined Ready category with a user-defined category that does not include activities that are waiting. A new user-defined category is defined for waiting activities.

tw.local.userDefinedCategories = new tw.object.listOf.ActivityListCategory();

// define a user-defined category to replace the predefined ready category, no waiting activies
tw.local.userDefinedCategories[0] = new tw.object.ActivityListCategory();
tw.local.userDefinedCategories[0].name = "ReadyOnly"; 
tw.local.userDefinedCategories[0].label = tw.resource.MyResource.category.ready;
tw.local.userDefinedCategories[0].sortCriteria = new tw.object.listOf.String();
tw.local.userDefinedCategories[0].sortCriteria[0] = "NAME_ASC";
tw.local.userDefinedCategories[0].filters = new tw.object.listOf.ActivityListFilter();
tw.local.userDefinedCategories[0].filters[0] = new tw.object.ActivityListFilter();
tw.local.userDefinedCategories[0].filters[0].executionStateFilter = new tw.object.listOf.String();
tw.local.userDefinedCategories[0].filters[0].executionStateFilter[0] = "READY";
tw.local.userDefinedCategories[0].filters[0].activityTypeFilter = new tw.object.listOf.String();
tw.local.userDefinedCategories[0].filters[0].executionTypeFilter = new tw.object.listOf.String();
tw.local.userDefinedCategories[0].filters[0].executionTypeFilter[0] = "MANUAL";
tw.local.userDefinedCategories[0].filters[0].optionTypeFilter = new tw.object.listOf.String();

// define a new user-defined category for waiting activities
tw.local.userDefinedCategories[1] = new tw.object.ActivityListCategory();
tw.local.userDefinedCategories[1].name = "Waiting";
tw.local.userDefinedCategories[1].label = tw.resource.MyResource.category.waiting;
tw.local.userDefinedCategories[1].sortCriteria = new tw.object.listOf.String();
tw.local.userDefinedCategories[1].sortCriteria[0] = "NAME_ASC";
tw.local.userDefinedCategories[1].filters = new tw.object.listOf.ActivityListFilter();
tw.local.userDefinedCategories[1].filters[0] = new tw.object.ActivityListFilter();
tw.local.userDefinedCategories[1].filters[0].executionStateFilter = new tw.object.listOf.String();
tw.local.userDefinedCategories[1].filters[0].executionStateFilter[0] = "WAITING";
tw.local.userDefinedCategories[1].filters[0].activityTypeFilter = new tw.object.listOf.String();
tw.local.userDefinedCategories[1].filters[0].executionTypeFilter = new tw.object.listOf.String();
tw.local.userDefinedCategories[1].filters[0].executionTypeFilter[0] = "MANUAL";
tw.local.userDefinedCategories[1].filters[0].optionTypeFilter = new tw.object.listOf.String();

// Define categories to be available
tw.local.categories = new tw.object.listOf.String();
tw.local.categories[0] = "ReadyOnly"; // user-defined
tw.local.categories[1] = "Waiting"; // user-defined
tw.local.categories[2] = "All"; // predefined

// Define initially selected category
tw.local.selectedCategory = "All";
