Marking fields having errors

["Kalra, Ashwani" <as...@capgemini.com>]

Hi,
Does struts has any facility to show fields having validation error in
red color or mark it in some way?

Thanks
Ashwani

Actually, this did not help me at all.  I understand that differences,
etc.  I just wondered what you thought, since I thought your conclusions
were contrary to the facts.
