This is really a ColdSpring question rather than a Model-Glue question,
so the coldspring-users Google group is a better place for it. I'll
offer my thoughts here but I urge you to post any followups to the
coldspring-users group. I am a member of both groups so you won't have
to Cc me.
A couple of things struck me with your example that might (or might not)
be related to your problem.
I don't like your choice of "objCollection" for the ID of the bean you
use for the phone collection. It may become tempting to reference that
bean anywhere a generic collection is needed, however since it's a
singleton ColdSpring will use the same instance in each place. You could
end up with one collection instance that serves as a phone collection
for one bean and as an address collection for another bean. To avoid
that kind of problem, I recommend a bean ID like "phoneCollection" instead.
In your init() method, the PhoneCollection argument is not required but
has a default of "". When using type="any" for bean arguments you should
not use default values that are not valid beans as it can make problems
like these harder to trace. I recommend making the argument required: if
you get an error after doing that then you may have a bigger problem in
more urgent need of fixing.
Cheers,
Dennis
