Our application works with a document storage and we use RadRichTextBox to allow users edit and view the documents. Unfortunately, many documents cannot be opened due to the following exception we get:
Unable to cast object of type 'Telerik.Windows.Documents.Model.FieldRangeStart' to type 'Telerik.Windows.Documents.Model.AnnotationRangeEnd
As result we receive complains from our users. Could you please facilitate with solving it?
I have attached a simple test application with the problematic document as well the stacktrace.
