Table field problem in runo that works with reindeer

I have a Table that uses fields that extend FieldWrapper from the CustomField add-on. The field is just a TextField in a GridLayout so a clicklistener can be attached.

Everything works great in Chrome when the theme is either runo or reindeer.

Everything works well in Firefox 8 and IE 9 when the theme is reindeer.

When the theme is runo, Table fields don’t show up properly in Firefox 8 and IE 9. Screenshot is attached below. I am using Vaadin 6.7.1.

I suspect the issue has to do with the theme and not the add-on, but I’m not sure.

The widgetset compiles properly. The analyze layouts button in the debug window shows no layout issues. I am using setSizeUndefined() throughout.

Any thoughts?
