Duplicate ID error for ReorderList in Repeater

I have a ReorderList in a Repeater and it's giving me "duplicate id" error because ReorderList is generating the same id for the DragDropBehavior. Is this a bug in ReorderList? Does someone know how to fix it temporarily in the source codes?

I think I find the fix. In ReorderList.cs ln 628, change from ID to ClientID will fix the problem.

dwp.ID =this.ClientID +"_behavior";

Hi aching,

This is related to a known issue affecting all our controls that wrap extenders. We hope to fix it pretty soon.

Thanks,
Ted
