help with celltable problem in devmode

[David]

I'm having a weird problem in most of my celltables that only happens in devmode.  Compiled javascript works just fine.  I'm using gwt2.3.3 and everything has been working for close to a year now.  The only thing that's changed recently is some css styling.  

Anyway, my cell tables initialize method  is failing with "String is not complete HTML (ends in non-inner-HTML context):"

Does this sound familiar.  Again, its only happening in devmode.

thanks
