Hi, sorry for the lack of details.
Here is the error stacktrace:

I get the error when choosing a filter not based on the 'filter textbox'. The demoes are working fine. I might add that we're using a custom datasource, but no methods is called in it when this filter is applied.

Hello Staron,

Thank you for the provided stack trace.

Is your ViewState turned off? Could you provide a simple example where the error can be reproduced on my end?
