"Bubbling" Event Preview

[Adam T]

I have a situation where a couple of my widgets want to use event
preview but the current code only allows the last event previewer
registered on the event preview stack to do so.

I can see the rationale behind this with respect to dialog boxes etc,
but for me this is too restrictive as my components need to monitor/
preview a number of events on the page (wrapping them in FocusPanel is
not suitable).

Looking at the DOM class' previewEvent method I feel I just need to
reorganise it slightly so it walks through the event preview stack
allowing registered previewers the chance to preview until either I
get to the bottom of the stack or a previewer wants to stop the
bubbling (thus maintaining the dialog box use case).

Am I missing any subtleties in the existing approach - are there any
GWT design issues if I try and step away from what is there presently?

Cheers,
