Hi,
I have 2 combos, the first one is filled and enabled, the second one is
empty and disabled.
There is a listener on the first one. When an item is selected, we fill
the second combo and we enable it.
Then we give the focus to the first combo but it seems that it doesn't
work. The focus remains on the second combo!
Does someone know something about it?
Thank you in advance for your help.
Best regards,
JUNG

Hello Ivan,
The version used is RAP 1.2.0.R.
Here is a sample code showing our problem.
At the beginning, when we select "2" in the first Combo,
the second Combo is filled and the focus remains on it.
If we select again "2", the focus is correctly put on the first Combo.
Thank you.

Hi JUNG,
we have recently fixed the bug:
289398: [Combo] Highlighting misbehaviour while setting selection
programmatically
https://bugs.eclipse.org/bugs/show_bug.cgi?id=289398
Your problem is not reproducible any more with CVS HEAD.
Best,
Ivan
