Bruce,
The question of why Castor XML cannot find the mutator when no "set-method"
is in the mapping file might be a question for Arnaud and/or Keith.
However, if you're fielding Castor JDO questions, then perhaps the question
of why it can't find the mutator when it _is_ defined by "set-method"
belongs to you.
What I don't understand is if both XML and JDO are using the mapping and
persist package classes, why should they behave differently with respect to
finding the mutator method.
I did some debugging and found that while the FieldMolder$ReflectService for
the collection field has an _addMethod (but no _setMethod), the FieldMolder
itself has _addable set to false. When CollectionProxy$ColProxy.close() is
called, it finds the FieldMolder not addable and calls setValue() for which
there is none.
I copied lines 592-593 of FieldMolder.java, which set _addable if there is
an add method, to line 650. This fixed the error.

B.T.W. This was with the 0.9.3.19 release.

I figured that Castor JDO would be able to find the mutator, but I
don't know about how Castor XML works. I've used the functionality
from Castor XML but I'm not familiar with it's internals. This
question would be better if aimed at Arnaud and/or Keith.
