Interesting enough, I have created an assembly extender rule that forces the default value for my RowSet into the cube view on my dashboard, as I am using a delimited list (default values can be kinda funky). This solved my issue if the dashboard is ran within the Application tab, but not OnePlace.
So, I applied the extender rule to the dashboard OnePlace references. It worked at first, but the error popped back up. It's weird, because again, if I run it from the Application tab (Yes, the DB applied to my WF Profile), I get no error...Is there a difference when ran from Application vs OnePlace that I am missing?
