java windows disappear from taskbar when filedialog is opened

likely a duplicate, do you get the same with karmic?

I couldnt find this bug when I searched for it.

I havent tried on karmic yet, as I dont have the release candidate yet. I will try again after I upgrade on the 30th ^^

ok thanks.

OK so on karmic the problem is slightly less. The window disappears from the panel, when a dialog is present, but reappears when the dialog is done.

I've seen similar problem with other java applications (Intellij IDEA) too. At some point java app disappears from the panel. Seen both on Jaunty and Karmic.

I have the same problem on Karmic with Intellij IDEA.

But it seems that Netbeans IDE is working fine. Both using Swing.

Same problem over here, on Karmic with Matlab and with Weka (a Java data mining tool). The windows are not listed in gnome-panel, until I click the "click here to minimize all button" in the gnome-panel.

The problem with Intellij IDEA occurs only if more than one instance is opened at the same time. If only one unstance is opened, then everything works fine.

Vadim, you are not quite right. The same problem reproduced when there is only one instance of Idea, but more than one window, for example: when you openning Diff window in addition to main IDE window.

Sorry, Vitaliy, I didn't test such use case.

This problem also occurs with Matlab

Running Adempiere
This program open several windows - every window opened appears in the gnome-panel.
When opening a dialog box - all the windows disappear but one, and when closing the dialog, this window also disappear from the gnome-panel.
Navigating with alt-tab and minimizing restore the gnome-panel as suggested above.
