interesting, maybe I misread the <any> documentation, but it made it sound like you had to specify a <meta-value>.
I forgot to mention, I'm using the latest 2.0 build. It looks like the TargetEntityType column gets set to the name of the class (just the name, no namespace or assembly information) but then when I try to load from the table, I get the following exception. Any ideas? Also, thanks for the quick help so far.
