InvalidOperationException in RadDocument.IsInNonEditableRange
I am constructing a RadDocument in code. The document is protected, but contains several permission ranges where editing is allowed. The sections where editing is allowed contain some custom readonly ranges to further restrict editing. When I assign the RadDocument to the Document property on a RadRichTextBox, I get the exception and stack trace below in the RadDocument.IsInNonEditableRange function. I am using UI for WPF version 2014.1.331.40. The exception and stack trace are:
System.InvalidOperationException: Sequence contains more than one element
