I have a dropdown byIndex which is being populated by calling a bapi.
I set that cardinality to 0..n
So I am getting blank row in that DD.
I dont want to change the cardinality to 1..1
But If the user selects the blank row in dropdown,on click of one button I want to show the error message saying that "Plz fill all Madatory fields".
But on action I am getting the Value of the attribute which is bind with the drop down.But that is giving null pointer exception. Tell me the proper way to do this..
Thankx and Regards,
