Team,
I have achieved the solution through automation script with action launch point which is triggered from custom button (for example: CUSTOM_OK) on dialog.
Solution:
- Add custom OK button into the Task node dialog (We can show/hide this button conditionally as required)
- Create sigoption for above mxevent name (LAUNCHDIALOG) in the application from where we route the workflow. From advanced signature option enable this option.
3. Create an automation script with action launch point for above mxevent/sigoption (LAUNCHDIALOG) with below logic. The object here is: COMPLETEWF (which is the object behind the task node dialog)
4. Task node dialog will be retained even when a Mandatory field error is thrown.
Hope this will be helpful. Please let me know for any doubts.
