If I'm understanding your email correctly, you're actually looking at a feature of Data Management. When you fill multiple client side collections and there's an overlap in the items each collection contains, Data Management ensures that only a single instance of any specific item exists on the client. This guarantees that your client side-data remains in a consistent state. Say you had two copies of 'media1' on the client, and then you change one and then the other. Which copy is the true copy? Which should be committed back to the server? There's no way to know, and this is a problem folks hit when using simple remoting to manage data. By maintaining a single instance on the client, your client-side data stays in a consistent, well-understood state.
If your media instances really shouldn't be shared by your model instances, then you'll need to adjust your domain model (always create unique media instances for each model?).

I have the following tables : model, model_media and media. I have made an hibernate "model" mapping with a Set from model to model_media, to get for each model their medias, like this : <set name="children" table="model_media" lazy="false"> <key column="modelid" /> <many-to-many column="mediaid" class="MediaVO" /> </set> I could retrieve data correctly, each model have their own media listed in the "children" Set. Some medias are used by several models at same time, for exemple : model1 - media1 - media2 - media3 model2 - media1 - media3 - media4 Now, when I display my hierarchical list into a Tree, there is stange behaviours... When I display all the hierarchy for all models, and roll over an item used several times, the selection focus is displayed on the last item... ie if I roll over the media1 from model1, the focus is displayed on the media1 from model2... It seems that the items used some times are referenced at the same memory allocation... Flex doesn't recognize each item as single item, it see item used several times as the same item... Anybody have encounted the same behaviours ?? I don't know how to resolve it... any suggestion are welcome, thanks in advance Thierry
