  • Is your task flow based on fragments or pages? – Florin Marcus Apr 14 '15 at 11:26

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:

  • How can i link the value of the dropdown to a Taskflow/Control flow. – JustCode Apr 14 '15 at 12:35
  • You will register a ValueChangeListener to your dropdown and from there you will call button's action programatically. Please check second blog.

If you know the basics then you will not how to call a action from from button ?

Now you have to just use the code from blog to call that Action using ValueChangeEvent
