Hi,

I am using EmbeddedXtextEditor for writing OCL expressions. It works fine in case of writing derivation statement of an attribute but when i want to write an OCL expression for operation's body and if operation has parameters then it does not recognize parameters. But if operation has no arguments/parameters then it works fine.

void org.eclipse.ocl.examples.xtext.essentialocl.ui.model.BaseDocument.setContext(EClassifier ecoreContext, Map<String, EClassifier> ecoreParameters)

In case of attribute derivation statement, i am passing null as ecoreParameters but incase of operation i am setting ecoreParameters arugument as map of eparameter's name and eparameterType of specific function. But doing so i am getting Exception as

Hi

This sounds familiar. I think I've fixed it. What code version are you
using?

Regards

3.3.0 is the Kepler release which stops changing in June 2013. Until
then you need to specify the qualifier as well to clarify what is involved.

A version of setContext is now deprecated. There is now an
EInvocationContext that should be initialized with your parameters. You
can check whether it is to see whether you have my recent fixes, and to
distinguish whether the problem is a failure to pass the parameters or a
failure to look them up.

org.eclipse.ocl.examples.pivot;bundle-version="3.3.0.v20121102-1800",

org.eclipse.ocl.examples.xtext.oclstdlib.ui;bundle-version="3.3.0.v20121102-1658"

I have tried to debug and it seems

@Deprecated
public @Nullable Object setContext(@NonNull EssentialOCLCSResource resource, @Nullable EClassifier ecoreContext, @Nullable Map<String, EClassifier> ecoreParameters) {
CS2PivotResourceAdapter csAdapter = CS2PivotResourceAdapter.getAdapter(resource, null);
MetaModelManager metaModelManager = csAdapter.getMetaModelManager();
resource.setParserContext(new EInvocationContext(metaModelManager, resource.getURI(), ecoreContext, ecoreParameters));
return null;
}
is being used with parameter map is passed properly.

Hi

I'm puzzled.
> org.eclipse.ocl.examples.pivot;bundle-version="3.3.0.v20121102-1800",
is an N-build a few weeks before M3, but all relevant changes should be
in that code.

should be line 43 in the current code.

(The extra line to support lookup of templated data type parameters such
as EList<T> was added just before Juno.)

I can see a mechanism for a loop for an interesting DataType declaration.

Please raise a Bugzilla and attach a zipped project.
