The ActivityStart action is a System Action that explicitly starts the execution of a Conditional Start activity in the process flow.

This System action is to be used in very advanced cases as it is neither trivial to obtain a Conditional Start identifier nor to pass it to a Web Screen or Screen Action. One easier way is to use the Start Conditional Start action where the ActivityId input parameter is replaced by the ProcessId.

If your Conditional Start has input parameters use the Start Conditional Start action. Otherwise you will get an error.

Input parameters

Activity Identifier Type. Mandatory.

Output parameters

Activity Identifier Type.


The On Start activity callback action is executed.

The On Start activity callback action is invoked using a different transaction and session from the transaction and session used when invoking the ActivityStart. Only the Session.UserId is transported.
