Hi,

I would like to model an operation with a parameter that is simple array of EStructuralFeature. But the following line raises an error

"type EStructuralFeaturesArray wraps EStructuralFeature[]"

Error Raised:
"Couldn't resolve reference to JvmType 'EParameter'"

Is it possible to do that? My meta-model already contains simple reference to EStructuralFeature but the definition of this new Data Type does not seem to work.

Thanks Wink

Regent,

Which version of Xcore are you using?

I can reproduce this with the Mars version, though the error is about
EStructuralFeature not EParameter. If I change it to be
org.eclipse.emf.ecore.EStructuralFeature[] then the error goes away, so
it seems yet another scoping problem.

It should be yes.

No, from a preliminary analysis, it seems to be a problem that an import
that can resolve to GenClassifier can't also be used to resolve to a
JvmType in the cached synthetic import section that's created... So
there's definitely something that needs to be fixed here. Please open a
bugzilla. This simple test case reproduces the problem:

package test

import org.eclipse.emf.ecore.EStructuralFeature

type Foo wraps EStructuralFeature

Regent,

I've opened https://bugs.eclipse.org/bugs/show_bug.cgi?id=466305 and
committed the fix. It will be in the M7 build.
