It looks like your sourceviewer was not loaded, try with various breakpoint
to check the trace.

Note that the CEditor comes with an extension point that lets you
add hovering,  for example we have contribution from the :
- the debuger
- the documentation
- source hovering

See CDocHover or CSourceHover and the plugin.xml of the cdt.ui
