UI only field displays blank in export file

Hi Experts!

I have this UI field added to the main model and am using a custom field renderer to display its values by looking up a field from my current row into another model and get back my display value. I see the correct data on the table but the export file has all blanks.

has anyone managed to successfully export UI fields based on a customfield renderer?

model.data - does not display my field even though I added it as a UI Only field on the model.



looks like my snippet was a problem, I used the MODEL_LOOKUP function to do the same thing and now I see it in the model.data and the export file too!
