Drop down values are setting.. Value disappearing on enter..

Hi ,

I have created a AET field in ERPADMINI and made it as dropdown.

when i select a value and press enter the value is disappearing from the field.

In debugging i have checked the setter method is setting the value perfectly and value is visible in the entity. but in the get method it is returning null value and in the entity also the value is cleared.

I'm clue less here.. The value is disappearing after the set method and before the get method call.

Please help.

Thanks

Krishna
