I have Data Source object. It's called "ACollection", and it's a container for "A" objects. So in the Data Sources, when i click on expand for that object, it shows all the fields from "A". From this list, I can drag them onto a report. So when i am showing a report, i simply set the data source to "ACollection".
Here's the problem:
I added a field to "A", and changed a field in a report to = this field. The problem is, the Data Source object is not picking this field up. I've tried removing "ACollection" and readding it, but that doesn't work. So how do i make this data source pick up the newly added field?
