Nested ReorderList - Javascript Exception

Any chance someone from Microsoft could look at this?
I can't believe there's no activity on this...this has to be a known issue. Would someone from Microsoft please chime in?

Here is the code I am struggling with:

Try to fix this in the Toolkit. In ReorderList.cs, line 637 try changing:

_dropWatcherExtender.BehaviorID =

this.ID +"_dItemEx";

to

_dropWatcherExtender.BehaviorID =

this.UniqueID +"_dItemEx";

Shawn,

Thanks a ton for taking the time to look at this--That fixed it! Should I submit a bug report on Codeplex about this?

Nah, I'll just check it in after I run some tests, etc.
Sweet! Thanks again, you rock!
