Igor,
Yes, that makes sense. However, I get the data for the list using a
single HQL query with joins and such. If I changed to a ListView
within a ListView, then wouldn't I also need to change to do many HQL
queries to build a bunch of small lists within a big list? I don't
know what the performance implications would be of making this change.
Also, last night I was working on switching it to a DataView instead
of a ListView. Could a single DataProvider supply the data for both
the outer and inner views?
Thanks!
