EVL not creating markers [message #1836509]

Hello,

Attached is a minimal example of an issue I am seeing where markers are not being created from EVL constraints when using the org.eclipse.epsilon.evl.emf.validation extension point.

I've attached a minimal example metamodel, evl constraints and example model. When validating the model, there should be 3 error markers created.

An error marker should be generated on the CPU for having a clock speed equal to 0 (Marker correctly generated)

Another error marker should be generated on the CPU for having an undefined name (No marker generated)

An error marker on the Board should be generated for having an undefined name (No marker generated)

As you can see from the console when running validation, the EVL correctly runs on the element and returns false, however no markers are generated.

Thanks,
Justin

Many thanks Dimitris,

After a little bit of digging, I don't think it is a bug. Looking at this bug report https://bugs.eclipse.org/bugs/show_bug.cgi?id=369383, I can see there is an additionalNamespaceURI tag.

Changing the com.example.electronics.evl plugin.xml to be the following, fixed my issue!

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.4"?>
<plugin>
   <extension
         point="org.eclipse.epsilon.evl.emf.validation">
      <constraintsBinding
            constraints="src/deployment.evl"
            modelName="M"
            namespaceURI="http://www.example.com/deployment">
            <additionalNamespaceURI
                  namespaceURI="http://www.example.com/electronics">
            </additionalNamespaceURI>   
      </constraintsBinding>
      <constraintsBinding
            constraints="src/electronics.evl"
             modelName="M"
            namespaceURI="http://www.example.com/electronics">
             <additionalNamespaceURI
                  namespaceURI="http://www.example.com/deployment">
            </additionalNamespaceURI>          
      </constraintsBinding>
   </extension>
   <extension
         point="org.eclipse.ui.ide.markerResolution">
      <markerResolutionGenerator
            class="org.eclipse.epsilon.evl.emf.validation.EvlMarkerResolutionGenerator"
            markerType="org.eclipse.emf.ecore.diagnostic">
      </markerResolutionGenerator>
   </extension>

</plugin>
