Ok lets just forget that.
I added server validation...
Everything working fine.. But just one problem.
Once if the error of form appear it doesnt disappear at al..
e.i, lets say i insert a special character in comment field, which is actually not allowed. so then the errors shows up.. thats cool.. but then if i just refresh the page or go other page and come back to the form page, that particular error will be still appearing out there.
Why is that so?
