Handlers for Subforms (Magic xpa 4.x)

Any event triggered when the runtime engine is in focus on the parent task will be handled for the parent task by using the handler hierarchy available. Any event triggered when the runtime engine is in focus on the Subform task will be handled for the Subform task by using the handler hierarchy available.

When you enter the Subform task, the control handlers are triggered in fast mode for the last control that the runtime engine is parked on. The Subform Control Prefix logic unit is executed, followed by the Task Prefix, and Record Prefix operations.

User-defined handlers specific to the Subform control are supported for the prefix and suffix level, but not for control verification.
