Greetings Mike, Indeed. Shooting is good. At least the data model you have and your app allow the adjustments to avoid the large faulting.
I do have an example where a 700 attribute with over 1000 entries is loaded into D2W. It can be done. The catch is that there is a machine with sufficient memory and one can adjust the JVM's memory footprint.

I was all over the wiki and didn't know I had to enable the wolips server. Works much better now! clickToOpen still isn't working, but my rule changes are. I'll check out your suggestion tomorrow David, something's definitely funky, but I certainly don't have that much test data in my DB. Maybe it's some of the self referencing on my objects.
