Hi,
I'm using the new ATL ant task included in ATL 3.0 under Eclipse 3.5 The
tasks work just like the AM3 ones with some minor name changes. However,
the xml extractor task under saveModel always throws a
NullPointerException. For example

<atl.launch path="ATL/Transform.asm">
<inModel name="IN" model="inModel"/>
<inModel name="owl" model="OWL"/>
<inModel name="XML" model="XML"/>
<outModel name="OUT" model="xmlModel" metamodel="XML"/>
</atl.launch>

<atl.saveModel model="xmlModel" path="x.owl">
<extractor name="xml"/>
</atl.saveModel>

Has anyone has similar issues? This occurs even with the simplest models.
Cheers,
Ronan

I have the same NPE with XML injection:

<atl.loadModel modelHandler="EMF" name="..." metamodel="XML" path="..">
<injector name="xml"/>
</atl.loadModel>

Is there a way to tell which injectors/extractors are available?
It seems to me that the NPE is really about the fact that the lookup for
the "xml" injector or extractor is finding nada and then kaboum...

Hey,
Yes it does seem like that alright. I think i remember seeing a similar
error back when the AM3 extractor didn't work a while back. I've filled a
bug as the error really should give more details than just a NPE. See
https://bugs.eclipse.org/bugs/show_bug.cgi?id=267338
Cheers,
Ronan
