OK, now we are getting somewhere. How are you connecting the
create PanelImage with the Panel? Are you connecting it? If it
is not an owned object you need to tell WO which object it belongs
with.
I thought that the relationship in EOModeler did that, but
obviously there is more to it.
My primary reference book is Josh Marker's and in his example of
this (chapter 7) he defines the relationship between the two
entities in EOModeler and then adds a WOToOneRelationship to the
display component. This doesn't look like the right solution for
me, because it appears that the WOToOneRelationship displays data
from the "other" table and that's not what I want to do.
It does much more than that.
He mentions sort of off-hand that this takes care of calling
addRelationship for you, which sounds like what I need to do, but
so far I haven't found any examples and the doc page isn't terribly
helpful (to me, anyway). I'm going to go look at the rest of my
books, but pointers would be helpful. Am I at least heading in the
right direction? :)
Yes. If a Panel always has a PanelImage, you can make it even easier
on yourself by making Panel "owns destination" on the relationship.
EOF will create the PanelImage for you (hint - don't create it again
yourself) and link them together.
