Hi Joana,
What is the HRESULT error code in the exception (if any)?
You should check the UDF U_U_U_TNWeight2P: name is strange... This is not the error, but functionally it's strange.
I'll do a check this night with it... But my guess is that the names of your UDF are too long: it exists (since always) a limitation regarding UDF names length and binding to data objects in the UI (don't know for DI, this is the check I want to do).
According to the SDK help file, UDF names can be 20 characters long, which makes in fact 18 (don't forget that B1 is adding U_) and this limitation becomes 10 (so 8 effective...) regarding dataobjects in the UI.
Writing this, but not sure at the moment.
Regards,
Eric
