I am getting a null exception when trying to bind a raddocument to a radrichtextbox: {Void RecalculateRowHeights(Telerik.Windows.Documents.Layout.TableLayoutBox, Boolean)}

Here is the stack trace:

Seem to have fixed the problem, but not sure how. Just rebuilt the code, and it worked. Have not done a full line by line comparison.
