Skip binding, set the dataprovider in a result handler from the server From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of wubac1 Sent: Friday, August 29, 2008 2:02 PM To: flexcoders@yahoogroups.com Subject: [flexcoders] Binding an ICollectionView completely in ActionScript to a ComboBox
I have a paged collection that implements the ICollectionView interface and can be bound the the dataProvider property of a component in MXML. However, doing this with a ComboBox can result in an empty dropdown if the dropdown is opened before the PagedCollection can retrieve an initial page. Once the initial page is retrieved, the ComboBox works fine. So, I'd like to avoid the initial timing related problem by binding to the ComboBox after I know the initial page of the PagedCollection is loaded (by way of a COLLECTION_CHANGE event). In order to do this, I suspect it is best to perform the binding completely in actionscript. I have looked at the code generated when binding an ICollectionView to a ComboBox in MXML. The generated code uses Binding and PropertyWatcher objects. While I could copy this exactly, I'm wondering if BindingUtils.bindSetter and the returned ChangeWatcher can be used instead. Thoughts on the best practice for performing this binding completely in ActionScript? Example code appreciated.
