ListView LongPress Exception

Using android galaxy s3. I have a listview for which the datatemplate is a textcell. If I have no contextmenu items defined, and press on multiple list items, it throws an exception and the app crashes. So I have no context items defined, I longpress the first list item, then long press the second, it crashes. Exception below:
