Yes, an example would help.
>From what you've described, it sounds like your modified setToggled() code is causing the RESET and that is the source of your problem. Take a look at the other methods in DefaultDataDescriptor that update attributes on nodes (setToggled(), setEnabled()) and follow that pattern and you should be ok. -deepa ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Alex Harui Sent: Monday, December 11, 2006 12:48 PM To: [email protected] Subject: RE: [flexcomponents] XML :: Tree :: XMLChangeWatcher Can you make a mini-example for us to debug? ________________________________ From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Michael Schmalle Sent: Monday, December 11, 2006 11:59 AM To: [email protected] Subject: Re: [flexcomponents] XML :: Tree :: XMLChangeWatcher Oh yeah, When I have the Tree scrolled and select a checkbutton and toggle it; This is a trace fromt he tree's collectionChangeHandler() override '' collectionChangeHandler() update collectionChangeHandler() update collectionChangeHandler() update collectionChangeHandler() update collectionChangeHandler() reset '' As you can see, right at the end a reset event.kind is comming through and that is what is resetting the tree.

Once it is in the change watcher and update is called and then a reset is called. In the change watcher, it hits the attributeAdded. path; initializeXMLForNotification() IXMLNotifiable(notifiable).xmlNotification(currentTarget, ty, tar, value, detail); currentTarget : the node the descriptor changed ty attributeAdded tar node value toggled detail true xmlNotification() case 'attributeAdded' itemUpdated() itemUpdateHandler(event); listChangeHandler() You know, as I am writting this I am running the debugger. I can see the update everywhere. It goes on forever. Then I step throught to the end and it's the last thing that happens. I can't find it right now but, right at the end it resets the tree.

Have/Can you narrow down which call is causing the RESET to be emitted? My attempts to add an attribute to a data item in the model via the descriptor or through the model itself always produce an UPDATE type of collectionChange event. Incidentally, we use the setToggled() method in DefaultDataDescriptor for menu-based controls. I'm assuming you're adding a similarly named attribute to your Tree's model to indicate to the CheckBox whether it should be selected or not? -deepa ________________________________ From: [email protected] <mailto:[email protected]> [mailto:flexcompone [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> ] On Behalf Of Michael Schmalle Sent: Saturday, December 09, 2006 8:35 AM To: [email protected] <mailto:[email protected]> Subject: [flexcomponents] XML :: Tree :: XMLChangeWatcher Hi, I have a little problem here. I have a check box tree that works fine most of the time. I have run into a bug that I didn't have before. I have debugged it using the debugger and found the 'problem'. When you assign an XML dataProvider, I use a dataDescriptor that sets an @toggled attribute on the model. The problem is, the XMLChangeNotifier sends an attributeChanged event and eventually down the line, the Tree gets a CollectionChange event that is a 'reset' right at the end of a toggle on the check box. The problem is, if the Tree is scrolled, it resets the scroll position to 0 every time becasue of the reset event. I have tried doing a hac blobk during toggle select but, it ends up messing the view of the Tree. How can I fix this?
