I have implemented the virtual list technique of Bruce's in a data separation model. I built the script and layout in the interface file of my data separation model and the calculated, display fields in the data file will not display in the portal in the interface file. If I run the exact same script from the data file, on a portal in the data file, the fields display properly. Is it not possible to get these fields with this technique to display in an interface file? I've never had a problem getting portal fields to display/update in the interface file until this. I've tried Refresh Window, Refresh Cache Join Results, re-set the primary key for the record to itself..., all the usual tricks, but cannot get the fields to display in the interface file. I can see the data in the variables in the data viewer in the interface file, but alas no display in the portal's calc fields. Would appreciate any help.
