Bug 316072

Description Paul Webster 2010-06-07 19:48:14 EDT

I was using the 4.0 SDK, clicking around.  I clicked on field while I think a javadoc window was coming up.  I got this.  We probably need to safe up BindingService.getActiveBindingsFor(*) and our calls to CommandServiceImpl.createCommand(*)
