I think i found a bug and maybe somebody can help make workaround.
Go to this page http://es.infragistics.com/products/jquery/sample/pivot-grid/custom-move-validation
1. Move Product dimension to rows on second place.
2. Open Date dimension filters and check for example 2011 and 2012 and click Ok. If you expand Date dimension, you will see, that all works correct.
3. Open Date filters one more time and check 01/02/2010 and click Ok.
4. Expand Date dimension and you wouldn't find 2010.
Best regards
