Missing widgets

Currently on SWT v3.6.0:

I am working on a tool and using the SWT as the GUI framework. I seem
to have stumbled across a bug that looks oddly similar to 298805. As that bug is supposedly fixed in 3.5.2, it seems like the bug is not the same one.

Problem: I am creating a wizard and one of the pages has tabs that get dynamically created when the page is viewed (as opposed to when the page is instantiated, which is when the wizard is first loaded). I have found that the first tab is always blank (no matter how many widgets I put) unless this page is reordered to be the first page in the wizard.

Quirks: I also found (in Windows 32-bit only so far) that if I change the tab icon, I can change tabs and go back to the first tab and the widgets will be displayed. As I noted, this did not happen in Linux. This suggests to me that the problem may be in the redraw() method. The comments for 298805 suggest that redraw was the cause, but does not go into further detail.

Bug 298805 is on Linux so it's not likely related to your problem.

Please provide some code to reproduce your problem.

Test Wizard Code that depicts the issue

Unzip the code into a plugin source and compile it. Use a standard WizardDialog to launch the CustomWizard. Tab0 will not have any items displayed. If you comment out TestPageNoTabs from being added to the wizard, Tab0 will have its items displayed. If you want, you can add an icon to the tabs to show that when you do that, switching tabs will allow Tab0 items to be displayed.

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.
