There was a hug brawl on the WOLips list about whether Entity Modeler should change this behavior or not. Originally I fixed it, and there was a great debate and it got removed. Head over to the wolips list to discuss this again.

I'd definitely be interested... because I noticed that it does the same thing, so I assumed there's some reason in particular that it's done that way. :-)

In the original EOModeler it was an out and out bug. I am not sure what is up with Entity Modeler. Maybe Mike was nostalgic for some of the old bugs. :-P

What's the workaround?

EOModeler generates SQL that results in a table that has ALL of the above fields defined as non-null.

This is a known problem. Mike has made a work around for the Eclipse Entity Modeler which works fine for me. If you're interested, send me a mail.
