[Xtext] Did you forget to configure the corresponding metamodel? [message #61907]

Hi,

I have a Checks.chk ffile with constraionts om my model. In this file I
use two metamodels. The one is the metamodel of the editor that is
open. The other is an external metamodel.

Whenever the Checks file is trifggered in the exitor I get the
following message:

Couldn't resolve type for 'crossx::ReferenceSymbolProperty'.
Did you forget to configure the corresponding metamodel?

The external metamodel I refer to is "crossx", so the xtext editor does
not know this metamodel. When this is run through a nworkflow file I
know how to registerv the metamodel, but how and where to do this when
triggered from the editor?

All references to the crossx project seem to be ok.

Hi Jos,

please double check that your crossx metamodel is registered in a
plugin.xml and that this plugin is part of your runtime environment.
Furthermore you have to overwrite your DslCheckValidator#getEPackages
and add the crossx package to the result list. Otherwise the validation
will not be triggered for eObject from the crossx package.

Hope that helps,
Sebastian

Sebastian,

The metamodel is registered in its own project:

<plugin>
<extension point="org.eclipse.emf.ecore.generated_package">
<package
uri = "http://www.mod4j.org/mod4j.crossx"
class = "org.mod4j.crossx.mm.crossx.CrossxPackage"
genModel = "model/crossx.genmodel" />
</extension>
</plugin>

It is used in some of the other plugins in the runtime environment. I even
have an Eclipse viewer opened on the crossx model.

I did overwrite getPackages(), but this didn't make any difference. It
shouldn't because all constraints are triggered from the other metamodel
(the one from the editor's model) . The crossx models are only used for
querying and finding information.

It seems that only when the constraints are triggered from the editor /
parser it cannot find the crossx metamodel. I am really puzzled by this
behavior.

Sebastian,

I have used the following workaround. In the CheckValidator I explicitly
register the crossx metamodel (see registerCrossx()) when it is configured.

public class MyDataContractCheckValidator extends
DataContractCheckValidator {

protected void configure() {
registerCrossx();
CheckEValidatorAdapter val = new
CheckEValidatorAdapter(DataContractDslPackage.eINSTANCE);
val.addCheckFile(new CheckFileWithContext("DatacontractChecks"));
val.addCheckFile(new CheckFileWithContext("CrossxChecks1"));

EValidator.Registry.INSTANCE.put(DataContractDslPackage.eINS TANCE,val);
}

protected void registerCrossx() {
EPackage.Registry.INSTANCE.put(CrossxPackage.eNS_URI,
CrossxPackage.eINSTANCE);
}

}

This works fine. I do not really like this woraround, but until I find
another solution I'll stick with this.

Jos,

what's the name of your DataContractDslPackage? It's not crossx, is it?

Regards,
Sebastian

Sevbastian,

No it isn't :-). Names of the two do not look remotely similar.

Hi Jos,

the only thing that comes into my mind is a second EPackage with the
name "crossx" in your registry, but with another nsURI.
Maybe you want to iterate the registry's content and double check the
known metamodels?

Is your project open source or is there some way to peek at the sources?

Regards,
Sebastian
