>             Project: Tapestry 5
>          Issue Type: Bug
>    Affects Versions: 5.3.0, 5.2.5
>            Reporter: Robert Zeigler
>            Assignee: Robert Zeigler
>             Fix For: 5.3.1, 5.2.6
>
>
> In 5.2.x, FormFragment switched from using direct calls to a "setVisible" 
> function on the fragment to using an event-based approach where the fragment 
> element listens for the Tapestry.CHANGE_VISIBILITY_EVENT or the 
> Tapestry.HIDE_AND_REMOVE_EVENT.  The current implementation, however, does 
> not allow for nesting form fragments because the event listeners do not call 
> event.stop(), so the event continues to propagate, so hiding an "inner" form 
> fragment hides the outer form fragment, as well.
