Vaadin 7.3.0

Hi guys,

I just update my vaadin app to vaadin 7.3 from 7.1.15.
We are having a problem that the tabsheet.tabs show the “errorindicator” even though no error has been occured. please see the attached screen shot.
we are using a runo based custom theme. it is working very well with version 7.1.15.

I would appreciate any help or tips.
