Hi Magnus,
You could do this by using a combination of a Converter and a
NullPolicy on a DirectMapping, which is slightly more work to map, but
makes your object model better.
You would need to do something like:
XMLDirectMapping mapping = new XMLDirectMapping();
mapping.setAttributeName("something");
mapping.setXPath("something/text()");
mapping.getNullPolicy().setNullRepresentedByEmptyNode(false);
mapping.setConverter(new MyBooleanConverter());
The way this mapping is currently set up, an empty node in the XML will
come back as "" and an absent node in the XML will come back as null.
The converter just needs to handle the conversion from those values to
a boolean:
@Override
public Object convertObjectValueToDataValue(Object
objectValue, Session session, XMLMarshaller marshaller) {
if(objectValue == Boolean.FALSE) {
return null;
}
return "";
}
@Override
public Object convertDataValueToObjectValue(Object
dataValue, Session session, XMLUnmarshaller unmarshaller) {
if(dataValue == null) {
return Boolean.FALSE;
} else {
return Boolean.TRUE;
}
}
Hope this helps,
-Matt

How can I do this? I cannot find a way to map this to a
Boolean.
Right now I create a descriptor for a dummy class, and
map
that
instead of the boolean. Then i get null or dummy object instead of
false and true
XMLChoiceObjectMapping something = new
XMLChoiceObjectMapping();
something.setAttributeName("something");
allvarligtFelIR.addChoiceElement("something",
Dummy.class);
But this feels wrong, and I really want a Boolean....
Thanks!
