Check your model for missing external type on one of your attributes.

I have the latest wolips nightly build and WO 5.4.3, mysql connector/j 5.1.7

I found this a post simillar to my problem at http://lists.apple.com/archives/webobjects-dev/2008/May/msg00882.html but this was a few months ago.

Does anyone know if this is already resolved?

Thanks,
Amiel
