Stephen,
The real issue I had turned out to be really stupid. In my mapping
file, I had reversed the field name and bind-xml name;
For example I had something like this:
<field name="name" type="string" >
<bind-xml name="WorldName" node="element"
location="defenseDesignDocument/planningContextHeader/world" />
</field>
<field name="name" type="string" >
<bind-xml name="PlanName" node="element"
location="defenseDesignDocument/planningContextHeader/OPLAN" />
When I really needed:
<field name="worldName" type="string" >
<bind-xml name="name" node="element"
location="defenseDesignDocument/planningContextHeader/world" />
</field>
<field name="planName" type="string" >
<bind-xml name="name" node="element"
location="defenseDesignDocument/planningContextHeader/OPLAN" />
I created my own unique variables in my java program and it runs fine.
Thanks,
Jason

Jason-
I'm having a little trouble reproducing the behaviors you're seeing, but
there are two things I can think of: one, in your mapping file, are you
mapping the two elements <name> to different fields in the java class?
(Might be a stupid question, but just want to check) And two, I did
have problems back in 0.9.5.4 with having multiple nested elements with
the same name (Castor tried to set one of the fields twice and the other
one was never touched).
As I dig back in my mail archive, it turns out Keith started working on
fixing this problem for multiple namespaces, but differing XPaths was
left as a somewhat academic discussion. So I might recommend setting
the two <name> elements with different namespaces just as an experiment,
and if that works, then maybe you can argue for the change up the line
(that's hard though, I know), otherwise, AFAIK Castor can't really
handle that mapping -- though if the other person has an XML Schema s/he
is working from, perhaps using Castor's SourceGenerator might give you a
set of classes that work.
Keith - Do you want to pitch in anything on this topic? I haven't
really been tracking progress in Castor XML and "advanced" mappings, so
maybe I'm missing something.
Sorry I can't be of more help.
