Hi,

I'm using the editor framework in my application and enjoying the
automatic propagation of errors. However, some of my sub-editors are
CellTable based HasDataEditors which aren't implementing
HasEditorErrors.

Here's an example of how I'm defining an editor for a list of Phone
numbers:

public final class PhoneTableEditor extends Composite implements
IsEditor<HasDataEditor<PhoneHandle>>,
                IndexedActionCell.Delegate<PhoneHandle> {
[...]
}

I tried simply implementing HasEditorErrors directly on this class,
but this results in a runtime class cast exception, so I guess I'm not
understanding the editor framework properly. I've read through the
editor framework documentation and I'm at a loss as to how I can
propagate EditorErrors into a HasDataEditor. Any ideas?
