Hi Experts

I have created a form in screen painter using SAP 2007 b PL 10. I want to add some values in combo box at form load event. It is giving error that Item -id is not correct. I am using B1DE 1.5 for creating addon. It is working fine on System Form but not on User defined Forms. I check properly the item id is correct. What can be reason. Plz give your suggestion
