Hi,
What is the best way to clean a combo or comboviewer with databinding
setting the model value? There is a good snipet for it somewhere? I searched
the snippets and examples and could not find anything.
Actually, using a ComboViewer, I am just able to do this calling the
deselectAll method. If I set the variable on the model to -1 (out of range
values) it is not working.
Thanks for any help.
Marcelo

Tom/Eric,
Thanks.
I was making the bind with the combo widget (inside the combo viewer) and
not the combo viewer itself. I changed to use the
ViewerObservable.observeSingleSelection and the set(null) cleared the combos
without problems.
Regards,
Marcelo
