Query of Query ?

Hi,

i have two custom post types:
– Community
– Group

Both are linked with a single taxonomy Category. For example:

“Community A” has Category of “Community A”
“Group 123” has Category of “Community A”

Since my Community items are created and also removed (to draft) quite often, i have a problem listing all Communities and their Groups. Groups can also be removed often too.

At the moment I have a Query Block for each Community, to output all Groups within. So the page has about 92 Community Query Blocks each printing out it’s respective Groups.

I’ve been trying to create A “Query of Query” block, to print out all Communities, but i can’t link the Groups in the child Query Block … If i set Taxonomy to Category and from “Current post terms” I get a blank Loop list.

Is it even possible to do that? Or should i be looking at a custom PHP solution? Or Is there another way to link Communies and Groups?

Thanks.
