Extending on this question:
I created a model extensing qx.ui.treevirtual.SimpleTreeDataModel which
fires "change" and "changeLength" events similarly to qx.data.Array. If my
store uses a qx.data.Array object as model and binds it to the controller's
model (which is the TreeVirtual's model actually), will this suffice for
data synchronization by
store.bind("model", controller, "model");
I am still not sure I fully understood the databinding architecture.
Thanks for any pointers,
Christian
