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

I would try setting the model value to null.

Hope this helps,
Eric

Or setting the ComboViewer-Selection to StructuredSelection.EMPTY.

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
