a!submittedOfflineTaskIds() Function

Function

a!submittedOfflineTaskIds()

In an offline interface in Appian Mobile, returns a list of offline tasks ids that the user has submitted since their last data sync. If evaluated anywhere else, returns an empty list. Use this to automatically remove tasks from an offline task report after a user submits them.

For a walkthrough of how to use this in a custom task report in an offline interface, see the Offline Mobile Task Report recipe.

Parameters

No parameters.

Returns

List of Integer

If you evaluate this function in an interface object or expression rule, it will always return null. It only returns a list of task IDs when evaluated in an offline interface in Appian Mobile.

Examples

This example shows a simple list of process task links. In order to test this example, you will need to set it up as an offline interface and view it in Appian Mobile.

To test this example as an offline interface in Appian Mobile:

  1. Create a task report and constant.
  2. Create an interface and enable it for offline mobile.
  3. Create a site and test the interface in Appian Mobile.
  4. Complete a task and verify it is automatically removed from the list.
