Thanks to you both!

I sent it, but I also discovered that after closing Eclipse for the
first time since creating the model and re-running it, the problem
went away. So maybe it has something to do with the model being
newly created.

Awesome.

Oy. On the plus side, though, this format probably lets me not have
to choose between PST and PDT. I just have to figure out which city
it uses for Pacific time. Which brings me to another question - how
do I access docs (say, to look up NSTimeZone) from Eclipse? I don't
see anything in the menus or the toolbar for this.

Nope, it's not greyed out, and I definitely have it marked as To One.

I think it would be clearer if the words "Select Attribute" contained
the down triangle, so there was a visual clue to click there. As it
is you click, then it goes blank with the triangle, you click the
triangle and then the list appears. If you could compress that, so
the triangle was there right after clicking the Add button and then
the drop-down list appeared on the first click that would help, I think.
I am not totally clear about the direction of the relationship. If I
have these two entities:
EntityA EntityB
eoid eoid
b_eoid stuff2
stuff1
and I want to join them so that entitya.b_eoid = entityb.eoid, which
is the source and which is the destination?
thanks again,
