We are having a random  problem with PivotGrid/xmlaDataSource Combination. This problem happens every now and then and once happens there is no-way of resolving it other than closing and re-loading the form.

It appears that the datasource stops re-freshing the viewModel regardless of what you do to the Rows/Colums/Filters. Attached is two screens where one of them shows viewmodel data even after everything was cleared from the data source. The second one shows the Datasource with cell data when it has no rows or columns.

Any feedback would be great.
