Ok. I'll try and come up with a simple test project for it. The biggest issue was it putting it in the wrong location (or looking for it in the wrong location) The biggest issue now is the non-validation of the attributes on the composite component and the lack of autocompletion on the composite components (both of whick are likely related?). I'll continue to look into and try and log an issue for it.
I will also try and get JBT 3.3 installed and see if that fixes everything!
Thanks!
