Description Elias Volanakis CLA 2008-12-09 15:29:45 EST
To reproduce:

- use attached snippet, or
- use this code sequence

combo.setRedraw(false);
combo.setVisible(false);
combo.setRedraw(true);
combo.setRedraw(false);
combo.setVisible(true);
combo.setRedraw(true);
combo.redraw();

Expected result: combo should be visible -- for other widgets (for example Text or button, this works as expected)

Observed with 3.4, 3.4 SR1, 3.5 M3

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
