Hello,
I've spent the day playing with the Tools plugin for Eclipse. Both Eclipse and the plugin are the newest versions available, I did clean installs today, and I'm on Linux (GTK version of Eclipse).
Things go just great until I try to view HQL results in the HQL Query Result View. The underlying error seems to be "Unable to create view: null argument", with stack trace

which gets triggered pretty much every time the Result View is accessed.
The weirdest thing is that this is not completely consistent -- sometimes I actually do get a resultset out of the database and it gets displayed as I'd expect. This is, however, just about 5% of the time.
Am I missing something in my installation here? There shouldn't be anything conflicting in the setup... getting a "null" in the assertion does not really even point me in any direction as to how to solve this :)
