mysterious eof problem:more updates

Somehow, it seems if I have _too many_ integer attributes in my entity... 
things stop working. As far as I can tell, it doesn't matter what the 
attribute's names are. It doesn't matter if they are class properties or 
not, or used for locking or not. It doens't matter if they are used as the 
source (or destination) of relationships or not.

I have 8 integer attributes, no problem. Add a 9th.... get the weird error 
I included before and will again.

Now, while I haven't looked, I assume that I've included 9 or more integer 
attributes in entities before without a problem. It's a lot of attributes, 
it's unusual, but it's not out of the question. I'm assuming I coudn't 
create a simple test case where I can demonstrate that it's _just_ nine 
integer attributes that are causing the problem. It must be more complex.

But I can't for the life of me figure it out. It's driving me crazy. I 
doubt anyone has any useful advice, but if you do, please.
