I tried making a custom marshaller and received and error. Here is a
part of my binding file:
<mapping abstract="true"
marshaller="org.regenstrief.queryposer.CustomMarshaller"
class="org.regenstrief.queryposer.QueryTransform">
<structure field="variable"/>
<structure field="subset" usage="optional"/>
</mapping>
This is the error I received:
Error running binding compiler
*** Error during code generation for file 'binding.xml' - please enter a
bug report for this error in Jira if the problem is not listed as fixed
on the online status page ***
org.jibx.runtime.JiBXException: Expected "mapping" end tag, found

Here is my marshal method:
public void marshal(Object obj, IMarshallingContext ictx) throws
JiBXException
{
String tagName = null;
//make sure the parameters are as expected
if (!(obj instanceof QueryTransform)) {
throw new JiBXException("Invalid object type for marshaller");
} else if (!(ictx instanceof MarshallingContext)) {
throw new JiBXException("Invalid object type for marshaller");
} else {
MarshallingContext ctx = (MarshallingContext)ictx;
QueryTransform transform = (QueryTransform) obj;
tagName = transform.getNodename();
ctx.startTag(-1,tagName);
ictx.getMarshaller(0,
obj.getClass().getName()).marshal(obj,ictx);
ctx.endTag(-1,tagName);
}
}
I am just trying to wrap a tag name around the actual serialized form of
the abstract mapping for QueryTransform.
