[ATL] Trying to capture record of transformation [message #103875]

For one type from my input model I'd like to capture a
trace of each instance to the output model. I've tried the
following code

rule x {
from in : IN!InType1
to out : OUT!OutType1 (
a <- in.a
),
trace : Trace!TraceLink (
target <- out
)
do {
trace.refSetValue('source', in);
}
}

I get the expected elements in my target trace model, but neither
of the attributes of these elements is set. I'm working with 3.0.0M6
and have tried with both the Regular and EMF specific VMs. Does
anyone have any ideas on what I might have done wrong?

thanks
Andy.

Hello,

To make references between input and output models, you have to check
the "Allow inter-model references" parameter in the advanced tab of the
launch configuration.

Best regards,

William

William,

Thanks. I know about the need to explicitly allow inter-model
references; why did my brain not realise that this was the problem!

BTW: I'm using a programmatic launch and have found that the
allowIntermodelReferences option needs to be present in the
options passed to the Launcher.initialize method for the Regular VM
and the options passed to the Launcher.launch method for the EMF
Specific VM. It would be nice if the two were consistent.

William,

When I set the allowIntermodelReferences option with the
EMF Specific VM I get the following exception; the Regular VM
works fine.

Hello,

Could you report a bug with your project (or a minimal version) ?
It would help me a lot to reproduce that exception.

Best regards,

William

Hi William,

I've now extracted a sensible sized example that demonstrates the
problem. It's reported a 274006. It looks like its associated with guard
conditions on rules.

Andy.
