The column filtering is working for me with your updates. I think having saved (session) settings for the web pages may have gotten in the way of testing the fixes. Thanks for all the help.

Apologies to jump on this one again!

When using the DataFilter component on boolean the .ToFilterString() is now causing an error. Supplied some basic information below which I know isn’t sufficient but may help point in the right direction while I pull more information together.

An unhandled exception has occurred while executing the request.
System.InvalidOperationException: Invalid predicate: x => (((x.Type == null) ? default(bool) : x.Type.IsComplaint) == true)

Thanks @Calarion! We will do our best to provide fix in our next update before the end of the week.
