During testing with end users a person got the a screen with red letters on the place where there was a datagrid. The first part of the error message was: Could not create widget mxui.widget.DataGrid: Error: Invalid template: dojoAttachPoint="searchNode" focus Index="0"> Since this is a standard Mendix widget from the modeler I do not understand what caused this error and how this can be fixed. I anyone could give some guesses as to what went wrong or explain where I can learn more on how mendix widgets get thier templates I would be very grateful.
