Adding validation errors (and handling exceptions) in JvmModelInferrer [message #937891]

How can I add validation errors found while trying to infer the JVM model (after cross-indexing, so they can't be checked in the validator)? I've tried injecting first ValidationMessageAcceptor (which couldn't be found) and then IDLJavaValidator. But it inherits this implementation from AbstractDeclarativeValidator:

	public void acceptError(String message, EObject object, EStructuralFeature feature, int index, String code, String... issueData) {
		this.state.get().hasErrors = true;
		state.get().chain.add(createDiagnostic(Severity.ERROR, message, object, feature, index, code, issueData));
	}

and state.get() returns null. While I've found I could initialize the state threadLocal by doing validation.setMessageAcceptor(validation).getState() 1) this is obviously wrong Smile

2) it still didn't work because state.get().chain was null.

So is there a proper mechanism for reporting errors from inferring the model?

I have this same question, which appears was never answered.

My JvmModelInferrer calls certain methods (e.g. reflection on Java classes), which may discover that the EObject being inferred is invalid.

Right now, I detect this error in the JvmModelInferrer and bypass inferring for that object.

Then, during validation, I run the same tests again, which discover the error and report it.

Is there a better way to do this, which will eliminate the redundant testing? (e.g. by reporting the error directly from the jvmModelInferrer as suggested by the original poster?)

You can add an instance of EObjectDiagnosticImpl directly to errors or warnings of a resource:
resource.errors += new EObjectDiagnosticImpl(severity, code, msg, object, feature, index, data)
