I think this is a little special ...
if you have 1..n relation to addresses this could make sense, but for a
relation order to positions this would be difficult. The only way cayenne
could provide a generell map is the PK an I don't think that this would be
helpful. All other attributes are nor
*shrug* that's what I've been doing thus far. But I don't think it's so
special... I find myself writing helper methods quite a bit. :)
As you point out, cayenne can't guess the correct key. But as a
developer, you know what things are (should be) unique. I'm not
suggesting that all to-many
?!

Currently (to the best of my knowledge), cayenne always represents a
to-many relationship as a java.util.List
ah, now i get your idea

I probably didn't explain myself very well, apologies. The values in the
map
Does that make sense?
yes
Am I the only one who thinks that would be incredibly useful? :)
I do too ;-)
Is something like this already planned for 3.0?
yes. In fact JPA spec that we are working on supports this type of
mapping. So Cayenne will too.
