Error Occurs When Triggering an Action Button

Issue

Object reference not set to an instance of an object. Even tried to remove and recreate the command options button in XMDesignerIs used to configure XMPro BPM solutions..

Resolution

The cause is the name change of the activityA specific step in a process.  It will be the user interface for that step (web form or a screen), for example, the Leave Application (screen interface or web form) will be the first Activity in the Leave Requisition process.  The Leave Application Authorization will be the second step or Activity in the Leave Requisition process.  One Process can have multiple activities.: From TAB_TE20Test to TE20Test.

When changing the activity name make sure the following are changed:

• Dynamic Description method name must be [ActivityName]_DynamicDescription() i.e. TE20Test_DynamicDescription(), which can be found in Activity Properties window > Identification > Dynamic Description

• Activity OnLoad / OnRefresh method name must be [ActivityName]_OnLoad() / [ActivityName]_OnRefresh() i.e. TE20Test_OnLoad(), which can be found in Activity Properties window > Content Definition > Managed Activity
