RE: [flexcoders] Re: Popup only works once
Cairngorm .99 should have the ability to unregister view
helpers from the ViewLocator so when this is released you
will need to unregister the View in the destruction sequence
of the popup. In the mean time there are these options (may
be more out there):
Alistair released a patch for Cairngorm some months ago to address this; the
patch will be part of the forthcoming 0.99 release:
The URL on Yahoogroups is:
http://groups.yahoo.com/group/flexcoders/message/6148
Here's the gist of the email:
public function initialized( view : Object, id : String ) : Void
{
this.view = view;
this.id = id;
ViewLocator.getInstance().register( id, this );
view.addEventListener( unload, Delegate.create( this, unregisterView
) );
}
private function unregisterView() : Void
{
ViewLocator.getInstance().unregister( id );
}
private var id : String;
private var view : Object;
Add that to the ViewHelper base-class, and it gives you a method that allows
you to
unregister the view; the motivation for this was people that were using
ViewHelper inside
Popup windows; when the popup window was destroyed with deletePopUp() it was
deleting the view, but keeping the ViewHelper reference - so we now ask
people to
explicitly unregister views in popups when they are destroyed.
Hope that helps in the interim.
Best,
Steven

Post a simple sample app.
Half the time, just the process of doing that reveals the problem.

If you're using the cairngorm currently available, your view helper is not
being deregistered. Search the archives for 'cairngorm' and 'deregister'.

Are you guys using the Cairngorm Framework? If so, does your popup window
have a viewHelper assigned to it?

RE: [flexcoders] Re: Popup only works once
The issue is that each time the Popup opens, the ViewHelper attempts to
register itself to the ViewLocator. The framework has a rule that a
ViewHelper must be unique in its 'handle' (done by the ViewLocator checking
if the View Name is already registered to it) otherwise it raises and Error.
(Code can be seen in the ViewLocator.as file).
Cairngorm .99 should have the ability to unregister view helpers from the
ViewLocator so when this is released you will need to unregister the View in
the destruction sequence of the popup. In the mean time there are these
options (may be more out there):
1. Modify the Cairngorm framework by not throwing an error in the View
Locator if the Name is already registered to it. (Not saying this is the
best option, just saying this is one way to do it)
2. Open up the popup window (child) without a view helper or a view helper
that doesn't have a name on it (if you are looking for code abstraction).
Have the child raise events that the parent can listen to. When the event is
raised have the parent broadcast the event (to the command) and have your
Commands talk to the parent to get the necessary information from the child
window.
I have found there to be value have the child popup simply raise events that
the parent (the mxml file that created the popup) is listening for in
several situations. Esp in any sort of master/detail relationship (address
of a user for example).
Hope this helps.
Ben

Yes, we're ussing the Cairngorm Framework and we're using a viewHelper in
the TileWindow.
How can I solve this problem? I can't use the viewHelper in this situation?
Thanks.
