System.InvalidOperationException: Sequence contains no elements

When try to expand inner group I get an error: System.InvalidOperationException: Sequence contains no elements.

Stack trace:

Note. This happens only whe I try to expand second level in group. ColumnGroupsDefaultExpanded and RowGroupsDefaultExpanded properties ot PivotGrid is set to "false" by default.

Hello,
We kindly ask you to post your technical questions/problems in the support ticketing system (http://www.telerik.com/account/support-tickets/available-support-list.aspx) as this is the best way to reach our support staff - the support system assigns a response time for all of your questions, depending on your license and ensures that all questions will reach the respective developers, if needed. Alternatively, you can ask the community for help by posting your question in the online forums (http://www.telerik.com/community/forums.aspx). We try to monitor these requests as well, but we cannot guarantee they will be answered properly and in the expected timeframe.
