Oh yeah, re-looking, the clue was in the stacktrace: > Render queue error in BeginRender
meaning you needed to load your entity sometime before that phase - i.e. setupRender() I don't what was causing the NPE though, loading your entity in onPrepareForRender() should have been okay. Looks like it's something do with T5's JSR-303 but I've never used it myself. Dunno if anyone else has any ideas? Steve.
