      Hi

      When errorString of the component is any value(ex 'Enter the value') then the borderColor of the component changes to 'red'. But when you make the errorString="" it does not change the borderColor of the component back for the first time.

      It change when the control lose focus.

      How can we make the border color to original when using errorString="" for the first time even the control does not loose focus.

      I have attached sample of the problem.

      Any pointers..
