Eclipse的启动配置TabGroup没有显示

Question

I'm writing an Eclipse plugin based on gdb-plugin. As said here I extended necessary classes (eg GdbLaunchDelegate) and as said, for example, here , added necessary information to Eclipse's extension points:

  <launchDelegate
delegate="neuromatrixplugin.fifoblocks.backbone.FIFOGdbLaunchDelegate"
        delegateDescription="FIFO Blocks GDB Launch Delegate 1"
        id="neuromatrixplugin.fifoblocks.backbone.FIFOGdbLaunchDelegate"
        modes="debug"
        name="FIFO Blocks GDB Launch Delegate"
        sourceLocatorId="org.eclipse.cdt.debug.core.sourceLocator"
        sourcePathComputerId="org.eclipse.cdt.debug.core.sourcePathComputer"
        type="org.eclipse.cdt.debug.gdbjtag.launchConfigurationType">
  </launchDelegate>

The problem is: tab group responsible for launch information doesn't appear with my launch delegate set so no information can be passed to delegate and it fails.

In the debug mode I noticed that TabGroup class gets instatiated (ie constructor is called, but returns no tabs). Adding specific launching types for my delegate (seen in the menu on the left) changed nothing.

Does anyone know what may cause that behaviour?

UPD The problem is most likely in extension point because even when I set original GdbLaunchDelegate itself TabGroup doesn't appear.

Apparently, Tabs should also be registered in extension points list separately like there . It's strange because it isn't mentioned in tutorials and isn't always necessary.
