IMO, the DataGrid in Basic should work with Arrays and a different set of beads allow it to work with ArrayList and another set of beads provides detection of changes to the ArrayList. As long as we have those beads (and maybe some tests/examples to prove it all works), the default set of beads is less important. That decision should be driven by users and maybe by us if there is some other goal we want to hit (like making an example be smaller than some number of bytes.
If you are going to create a style definition of DynamicDataGrid should also create a DynamicDataGrid class that packs in the required set of beads. The DataGrid in Express will likely evolve to pack a set of beads that don't care if the data provider is an Array or ArrayList. For now it can just assume ArrayList.
