How do you "edit as an expression" in UI?
The tutorial on creating a web service for version 7.3 located here references pre-UI steps when asking the student to create a form and then click on the data tab and then "edit as an expression".
AIUI, the expression editor cannot be used in UI as it "has a different concept of data".
What to do in this situation? There is the 6.x application tab however I would rather not if possible try to learn the legacy way of doing things.
Should I even be trying to insert a script into a table on an application form or is there a different v7 approach for processing data from a web service.
