[Cdt-launch-inbox] [Bug 206928] New: Launch config settings are not displayed in C/ C++ Postmortem Debugger -> Debugger Tab 
https://bugs.eclipse.org/bugs/show_bug.cgi?id=206928  
Product/Component: CDT / cdt-launch
           Summary: Launch config settings are not displayed in C/C++
                    Postmortem Debugger -> Debugger Tab
           Product: CDT
           Version: 4.0.1
          Platform: All
        OS/Version: Unix All
            Status: NEW
          Severity: major
          Priority: P3
         Component: cdt-launch
        AssignedTo: cdt-launch-inbox@xxxxxxxxxxx
        ReportedBy: piotr.kundu@xxxxxxxxxxxx


Build ID: M20070921-1145

Steps To Reproduce:
1. Open the debug dialog (Run -> Open Debug Dialog)
2. Create a new C/C++ Postmortem Debugger launch configuration.
3. Choose a project and application (optional)
4. Open the Debugger tab.
5. Change the string (e.g. gdb) in GDB Debugger field to "test".
6. Press Apply and go back to the Main tab.
7. No open the Debugger tab again, and your settings reset to default values.

Note: The Apply button is enabled, but if you change the GDB Debugger field to
"test" (or whatever you typed in step 5), the Apply button will be disabled.

More information:
The settings are properly stored to the *.launch file, and the issue is merely
the fact that they are not displayed in the debugger tab. 

The solution is to remove the activated() method in CoreFileDebuggerTab
(org.eclipse.cdt.launch.ui) which will force CDT to use the 

activated() in AbstractCDebuggerTab. This is the way it's done in CDebuggerTab
(org.eclipse.cdt.launch.ui).

You can also see that the AbstractCDebuggerPage object (e.g. GDBDebuggerPage)
is created more times when creating a launch config for post-mortem than for
Local Application. (Set a breakpoint at createControl())

To accommodate a swift apply of the fix, we have tested this extensively on
Solaris 9, Solaris 10, Suse Linux, Redhat and Windows. 

Note: This issue is working on Windows, we wanted to make sure that the fix
does not break anything.

PS. The above solution is provided by Stefan Bylund, Enea Software AB, Sweden.
