DropDownbyIndex problem

Hi all,

I have enhanced a standard web dynpro component, I have added a dropdownbyindex custom field on the screen. Every thing is going as per my requirement. Now the value I selected in the drop down box is getting refreshed, but I am able to capture the value selected. My problem is the value selcted is getting refreshed(value getting disappeared on the screen).

Info on this ia highly appreciated.

Thanks,

Krishna
