I don't know whether this is the expected behavior, but when I create a screen and try to assign it to a task in my process, it doesn't seem to stick.
Specifically, I'm talking about "Screen for input" box in the "Edit Process" page. When I click the dropdown button, it shows my screen's name (strangely with red background). When I select the screen its name is displayed in the box. But when I select another task and then go back to the first, the box is still empty (with the dropdown list opened). I tried saving after selecting the screen, but when I backed out and choose to edit the same process again, the box would still be empty.
Any idea what I messed up?
