Hello again!
I traced a bit into the code and found the problem seems to be the
"ContainerFieldHandler" - It's not an "ExtendedFieldHandler".
The problem comes up when the first "<path name="/eng/hamburg"/>" gets
unmarshalled. The "UnmarshallHandler" is looking for constructor
arguments and the current "ContainerFieldHandler" is not able to
handle them...
--- UnmarshallHandler.java ---
Arguments args = processConstructorArgs(atts, classDesc);
if ((args.values != null) && (args.values.length > 0)) {
if (handler instanceof ExtendedFieldHandler) {
ExtendedFieldHandler efh =
(ExtendedFieldHandler)handler;
state.object = efh.newInstance(parentState.object, args.values);
}
else {
String err = "constructor arguments can only be " +
"used with an ExtendedFieldHandler.";
throw new SAXException(err);
}
}
------------------------------
Any ideas if it's possible to extend "ContainerFieldHandler" to
implement "ExtendedFieldHandler"?
Some help from the Castor "gurus" would be appreciated!
Regards,
Michael
