Bug can be observed using the Demo => PivotGrid => More OLAP Examples

Setup like so and hit refresh


A customer reported this issue. We could observe that the memory of the process was exploding, this doesnt happen in the demo for some reason.
Using the old RadarSoft  WinForms Pivot Control, the same view that our customer had issues with, is loading in a reasonable time.



Please also make sure that in future releases you add some cancel functionality so one doesn't have to restart the application....

When overriden in a derived class the GetAllNames method receives an empty IEnumerable in the "parentGroupNames" parameter.

See the attached image.

Steps to reproduce:
1. I checked the checkboxes 'Product' and 'Price'. The Product field added to row labels, and price to values.
2. Unchecked the 'Price', the price field removed from the pivot.
3. Unchecked the Product, doesn't  remove the products from the pivot.

It happens when you change the distinct values selection several times. The PivotGrid disappears after the exception is thrown.
I managed to reproduce it in the demo by repeating this action around ten times.
