WebObjects version = 5.4.3
I took a closer look. It seems to be happening only on one Entity hierarchy. It was real noticeable on that hierarchy since it was the most subclassed. The other hierarchies seem to only query once. Now I need to figure out why.

I know this is how the inheritance was designed originally. Has anything been done so that it does on query and applies the qualifier in memory to determine the entity type? I want to make sure I am no missing something.
