Keith,
Thank you for the reply. I saw your earlier message on this issue and I did
try new code from CVS before I posted to the list. I might be msitaken, but
I think the problem that people reported was slightly different from the one
that I have:
This works fine with the new code:
<field name="B1" type="B">
<bind-xml name="B1" node="attribute" location="B"/>
</field>
<field name="B2" type="B">
<bind-xml name="B1" node="attribute" location="B"/>
</field>
But this still does not work on unmarshalling:
<field name="B1" type="B">
<bind-xml name="B" node="element" location="B1"/>
</field>
<field name="B2" type="B">
<bind-xml name="B" node="element" location="B2"/>
</field>
( the corresponding java code and xml are in my original message )
Also, I noticed that when the same name of the xml element is used inside
and outside of location tags, it also results in error during unmarshalling,
but marshalling works fine. For example
java:
public B getB();
public B getB1();
mapping:
<field name="B" type="B">
<bind-xml name="B" node="element"/>
</field>
<field name="B2" type="B">
<bind-xml name="B" node="element" location="B2"/>
</field>
xml:
<B>blah</B>
<B2><B>blah</B></B2>
It is possible to create a mapping file to support this? Any insight is
greatly appreciated.
Thank you,
Yelena

Yelena,
This issue was fixed last week in the CVS version, so if you can grab
the sources from CVS and run the build script. More information on our
CVS server can be found here: http://castor.exolab.org/cvs.html
