[QVTo] Running from Java: Adding two models [SOLVED] [message #660455]

Hi,

I'm running a transformation from Java according to this example, however I want to send two models to the transformation. I've already tried to add the objects manually to the inObjects list via the addAll method and it looks fine when I look at the variable in debug mode, but I still always get the same error:

Diagnostic ERROR source=org.eclipse.m2m.qvt.oml.execution code=140 Invalid number of model parameters. Received (1), expected (2) data=[]

Any ideas?

Hi Haffi;

I use two models as input in a transformation, called programmatically. To have more than one input models it is necessary to create another ModelExtent object and pass it to the execute method in ExecutionContextImpl (this method uses varargs). Here is an example:

ModelExtent input1 = new BasicModelExtent(model1.getContents());
ModelExtent input2 = new BasicModelExtent(model2.getContents());
ModelExtent output = new BasicModelExtent();

ExecutionContextImpl context = new ExecutionContextImpl();
ExecutionDiagnostic result = executor.execute(context, input1, input2, output);

I hope it helps.

Regards;
