I ran into an issue the other day when chaning my datasource from test data to real data. I was suddenly getting Null Exceptions in the JumpList code. I tracked it down and it turned out to be that one of my objects had a null value in a property that was set to the GroupDescriptor. I fixed this by puting extra code in to trap this scenario, but I thought you should know about it.
Thanks
