[cdt-dev] Problem with refactoring change preview

[Viet Le <lviet@xxxxxx>]

Hi all,

I'm creating a refactoring plug-in for CDT and having this problem. The 
change preview doesn't show anything but an empty gray rectangle. The 
changes generated are correct when I click OK. Normally, if there is no 
change or an error, it would show up a message, but that is not the case 
here.

Do you have any clues? Please help...

Thanks,
Viet
