Using a portal to display records in found set
I am trying to create a portal to display the contents of one field in a found set, while omiting duplicated values. E.g. There are 214 image records, and each has a 'folder' reference. 25 from one folder, 32 from another, etc. I'd like to display in a portal a list of folder references omiting the duplicate values. Maybe a portal is not the solution, as it does not allow me to display results from the same table. Suggestions?
