Looks like you're using trunk/0.6. The macro syntax has changed completely in that version. The equivalent of your example would now be:

[[ListTagged(foo closed realm:ticket)]]

I haven't updated the documentation yet and the error message could certainly be clearer. I'll leave this open until I've clarified the docs.

This is a valid problem, I am using trunk, as of the latest patch. I have a few default pages for the sites I create. I know that I will eventually fill in the tags, so I put them up. Then I Include them in a few other stock pages. Hence, I hit this right away. I will try to cook up a patch.

this line

[[ListTagged(network realm:wiki)]]

When no wiki pages are tagged network

This was fixed in r3067.

(note to self: I should probably put in a warning if people use the old syntax)

Warning added in r3068.
