TRichView.com

It wasn't a problem on the side of TRichView.
As you said, the TRichView component requests the data as stream and the default RichText asks for a string. The JIT Pipeline we had only delivered a string, so I had to add another event handler to return data as a stream.

I'll try to do that, but it might take some time.

Same Problem here, also got a RichView using a JIT Field. The other RTF is showing without problems
