Hi there,
I've figured this out for myself, in case anyone else has the same problem,
I give my fix here.
For some inexplicable reason, requesting only some of the attributes for an
element to be bound causes inconsistent binding i.e.
<element id="one" name="element" size="2">
....
</element>
Requesting only id and name be bound causes one or more to NOT be bound to
the corresponding attribute in the Java class. If you change this to bind
all (add fields to mapping file and attributes to Java Class), then the same
mapping will work fine, this is even though I'd set ignoring attributes to
true for hte unmarshaller i.e.
unmarshaller.setIgnoreExtraAttributes(true);
There may be a better way and if anyone knows of one then please do post a
reply.
