Oracle Forms

Hi Masters

I have a text item , which i want to change to list item. The text item is a database item and refernces a column. I have changed that in the property palette to list item. I am trying to populate the list item with a record group.

when the item is text item i am able to get the records and display on the screen. but after changing it to list item i am not able to get the records.

I am getting "Query caused no Records to be retrieved" error. and
"Cann't populate the list from the record group"

Please tell me what is wrong i am doing?

Thanks in Advance.
