Solaris 9 on SPARC
Synopsis: Violation of precondition `visible' of {SD_CONTENT}.set_focus
Description
Typing ctrl+Tab, closing a tool displayed in the resulting popup window and
then selecting the tool that was just closed from the ctrl+Tab popup
causes a crash with violation of precondition `visible' of {SD_CONTENT}.set_focus.
To Reproduce
Delete ~/.es_wkbench directory. Start workbench estudio and open existing project. Move mouse over Clusters window. Type ctrl+Tab. Popup window showing available tools comes up and stays displayed. Click on "X" in Clusters window to close it. Move mouse into Ctrl+Tab popup window and click on Clusters icon. Estudio crashes with attached trace.
Problem Report Interactions
Still reproducible with 7.0.86747, but only on CDE. Cannot reproduce it under JDS.
This problem is not fixed in rev 71123 on Solaris 9 on SPARC. Reopening report. Another way to reproduce this same crash is to type Ctrl+Tab and then click on a the name of a tool in the resulting popup window which is in Auto Hide mode and which is not currently visible (e.g., the Metrics tool in the default configuration). I just did this on rev 77123 and got the same or a very similar exception trace.
Hi, David, This bug is fixed in revision#69408. Thanks for your report. Larry
You said: But on your desktop system, I guess the focus out actions have not been called on the ctrl + tab dialog. That is correct. On my Solaris 9 SPARC host under CDE, when I type ctrl+Tab the dialog appears. If the mouse pointer is not inside the ctrl+Tab dialog when it appears, then when I release the Ctrl key the dialog does not disappear. In contrast, on my Solaris 10 x86 host under JDS, once I release the Ctrl key Ctrl+Tab dialog disappears whether the mouse is inside that dialog or not.
I can't reproduce this problem on my Solaris 10 CDE or JDE. The reproduce AVI video is attached. The key of this problem is: After displayed ctrl + tab dialog, if the dialog lost focus (this is the time when I press the close button in Cluster/Features tool), the ctrl + tab dialog will disappear before my pointer button release. But on your desktop system, I guess the focus out actions have not been called on the ctrl + tab dialog. Maybe this is a problem of Solaris window manager. I'll go on investigation.
