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.
