Hello, I am recieving an exception when trying to export my datapresenter (XamDataGrid) as an Excel file. The error is below.

I have my own FieldLayout class so that I can convert my serialized data easily to a FieldLayout. I also have my own class that bases from Field and it also does the deserialization to a Field for me. These two classes both have a default, parameterless constructor defined. The grid works as expected at runtime when using these two classes as the FieldLayouts and the Fields. How do I track down this error? Has anyone ran into this issue before? This happens when using the DataPresenterExcelExporter and the Infragistics.Windows.Reporting.Report by calling the Print method.

No parameterless constructor defined for this object.
