Re: [flexcoders] Finding out when an arraycollection in my model is set
Even though you have a solution to your problem, I would strongly suggest looking at how the listBase sets its dataProvider. After it has gone through the process of setting its protected collection property, it creates a new CollectionEvent with the kind set to CollectionEventKind.RESET. It then passes the event to its internal collectionChange_eventHandler method and also dispatches it as well. So if all the other suggestions above don't seem to work, then maybe this can provide some insight. Hope that helps someone.

Re: [flexcoders] Finding out when an arraycollection in my model is set
Interesting question ...
Did you try the method described in this thread ?

Hello,
How can I now when my arraycollection in my modellocator is filled with
items ?
I tried using collectionEvent. collection_ change, but it does not fire
when
setting my AC like this in my command, after the remoting result
handler:
model.library = new ArrayCollection( data.result) ;
What is the correct way ? ( I'm using Cairngorm )

Thanks fellow Flex coders;
Slangeberg's tip did the trick I was looking for ; )

You can use simple binding, via {} brackets.
MyComp dataProvider={model.library} /
Or, you can use the ChangeWatcher:
ChangeWatcher.watch( model, library, onLibraryChange );
function onLibraryChange(){ /*do stuff*/ }

Re: [flexcoders] Finding out when an arraycollection in my model is set
I'm getting my data back from a Ruby service. The service method I'm calling is query of joined tables. RoR returns this as an array of AlbumVO's. Every AlbumVO item contains an array of TrackVO's. That's the way it works. To be able to use this data structure in my datagrid, I have to loop through the data and rearrange it into a usable dataprovider for my datagrid. That is the reason I have to now when the model.library is loaded; so I can transform my data into a usable ArrayCollection.
Re: [flexcoders] Finding out when an arraycollection in my model is set
You can use simple binding, via {} brackets.
MyComp dataProvider={model.library} /
Or, you can use the ChangeWatcher:
ChangeWatcher.watch( model, library, onLibraryChange );
function onLibraryChange(){ /*do stuff*/ }

Re: [flexcoders] Finding out when an arraycollection in my model is set
Hi, Why not just make it a get, set bindable property in your ModelLocator? Then you could dispatch and event or really whatever you want to do.
