Hi,

I'm working on a tool which uses a modified version of Dennis' command
line ATL launcher (see attachment for the relevant snippet).

The tool correctly executes ATL transformations, except in the case
where there are multiple input metamodels and/or multiple libraries.
In that case the tool correctly invokes the ATL engine, but the engine
itself fails. When I execute the same transformation from Eclipse,
using the same (meta)models, the engine works correctly.

I've attached a log containing the backtrace and the files to which make
up the transformation.

Environment:
* JDK 1.6b2 (!)
* Eclipse 3.3
* EMF 2.3
* ATL 2007-02-16

Any ideas?

Regards,
Rene

You use two models named 'IN'. That's not even possible in the Eclipse
interface, so I think you intended to do something else ;-).

Dennis

P.S. All models go in a Map with their name as key. Only the last 'IN'
model is accessible by ATL.

Yes. I changed the name of the parameter model (the one with the XML
metamodel) to 'parameters' as specified in my ATL files, it works now.

That would have been the input model (I got it partially correct the
first time :) )

Thanks,
