Combo-Box inside A browse crashes after changed-value.Please help..

hi progress users,
I started to use OE Architect 10.1C. The combo-box inside the browse will not give an error if the list-items are listed during the design time in the properties window. But what I did was filling the combo-box after the browser is realized(during runtime).

Anyone has encountered this problem before? Please help if you have some suggestions.

I've already visited the knowledge based.(Still under investigation)

Thanx in advance.
