DropDownByIndex

Hi All,

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,

Karthick
