Vaadin 7.0.3 'Required' Indicator Problem

On 7.0.3, the ‘required’ indicator is not appearing in my data entry form. (It was working in 7.0.2). The form is on one of the tabs of a Tab Sheet and if I switch the tab to another one and switch back, it will appear. Then, indicators won’t go away after the editing is over and the form is in read-only mode. It will go away if I switch the tabs again.

I haven’t created a test case yet. I wonder others have experienced anything like this.
