Thanks for the brief reply, however i am facing one issue in this. Say i have entered a wrong value and the error message popped up on screen as expected. however if the choose wrong value again the same message appears 2 times . looks like the previous message is not erased. FYI , actually my edit validate rule was not executed earlier, from google I applied this solution- on the section where i used this date property, I used post action and refresh this section action on change. after that the validation was executed. but i guess due to that my previous error message is also appearing on screen along with the second error message. Any thoughts on this please.
