Return value of taskflow as region in fragment.

Question

Hello All,
I would like to ask a question about region, task-flow and its return value.
I have one task-flow which I want to use it everywhere in my application. It shows a list according to its parameters, make users to check some of the values and return the checked values as a list. It has 4 input parameters and one return value (which is the checked items that caller want). There is no problem when I use it inside taskflow with task-flow-call activity. But when try to use it inside fragment (popup) as a region(or dynamic region) I can't get the return value of my task-flow. It's because I can't find a "return value option" in a region.
How can I get the return value of this task-flow when I use it inside fragment (or popup)?
I've searched from this forum, googled it and found nothing.

Hi,
there are many solutions to this but one, the one you expect doesn't work. You could define a managed bean in the calling task flow (put it into view scope) and pass it as an input parameter to the task flow. In the task flow you then change the managed bean before you exit the task flow. Then in the calling task flow, you access the managed bean to read the return value from it. This is how the Dynamic Tab Shell template does it with the tab context. This should work for you as well
