Answer 1

I would put this problem in a different perspective: what you are trying to do is to invoke an navigation action of the current task flow. This action can be firing a task flow call.

Presuming the current task flow has an action named "gotoTF1", action pointing towards a Task Flow Call activity, you should have an af:button with visible=false and action="gotoTF1".

Please find below few blogs, explaining this in more detail:
