Hi Paul,

This is not a known issue. Looking at the call stack it appears that
perhaps the pipeline for the field chosen is invalid or not present. I
would need to see an example of this in order to understand exactly what
is happening.

If you are able to run this on your machine, perhaps try placing a break
point inside the TppLayoutFactory.ContainsRTFData routine to see exactly
what is happening to cause the error. Otherwise, you can send me an
example and I can test it here.
