When I try to set the grid's Datamember property i get the following message:

Nullreference Exception

Object reference not set to an instance of an object

Source: Microfour Strataframe Extensibility

Stack Trace:

at Microfour.Strataframe.Extensibility.WebBusinnessBindingSource.GetView(String viewName)

After that, everytime I click on the grid I get the same message  and have to click on the OK button several times to get rid of it.
