[eclipselink-users] XMLTransformationMapping problem

[Magnus Heino <magnus@xxxxxxxxx>]

Hi.

I have a bunch of attriutes gml:id="someid" in my xml that I need to have when writing xml, but that I don't care to map to my model.

In other code, when I needed to do such a thing, I created a mapping like this:

XMLTransformationMapping faultCodeLang = new XMLTransformationMapping();

faultCodeLang.addFieldTransformer("env:Code/env:Value/@xml:lang", new ConstantTransformer(Locale.getDefault()));

fault.addMapping(faultCodeLang);

this worked just fine, so this time I created a FieldTransformer that returned a random id on every buildFieldValue call and added the mapping:

XMLTransformationMapping realPropertyReferenceGmlId = new XMLTransformationMapping();

realPropertyReferenceGmlId.addFieldTransformer("building:realPropertyReference/@gml:id", new GmlIdGenerator());

building.addMapping(realPropertyReferenceGmlId);

But this time, when I unmarshal my xml I get this exception.

java.lang.NullPointerException

Any hints of what might be going on? I have tried debugging to come up with something, but without any luck... 

NamespaceResolver:160 gets called with a null namespaceURI btw...

EclipseLink 2.1.0 (same thing in my old patched 2.0.1)...
