User, the same answer given in your other question https://community.oracle.com/tech/developers/discussion/4506571/elexception-java-lang-nullpointerexception-in-adf-jdeveloper applies here. The EL used returns null at one point. Either the bean 'DirectionPlanPageFlowBean' is not defined in the page flow scope of the task flow that is using the fragment, or the name of the bean is wrong.
How have you added the action to the button?
Did you use the binding editor on the right side of the action property?
This will show a dialog where you can select the right scope and the bean available in the scope.

@Timo Hahn Thank you Timo Hahn. I didn't really define a method in application Module! It works now, thank you again!
