Re: GWT 2.4 - problems with space key handling and FieldUpdater for TextInputCell inside CompositeCell in CellTree

Looks like it boils down to events. After looking at the TextInputCell
and AbstractInputCell source, I added "focus" and "change" events to
the list of events consumed by the CompositeCell, and that addressed
both issues.

Incidentally, I tried out the EditTextCell in the CompositeCell, and
to get that working, I needed to add "keyup" and "keydown" events to
the CompositeCell.

Clearly I do not yet have my mind wrapped around how the events are
propagated in a CompositeCell, but at least I've solved my immediate
problems.
