Hi,

I have 2 ecores in my project having the same contexts in it with same namespace. I want to validate based on one of the ecores. I use a check language and write workflow files to validate.

My workflow file:

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<workflow>
<component class="org.eclipse.xtend.check.CheckComponent">
<metaModel class="org.eclipse.xtend.typesystem.emf.EmfMetaModel">
<modelFile value="actual path of the ecore"/>
</metaModel>
<emfAllChildrenSlot value="model"/>
<checkFile value="CheckFile"/>
</component>
</workflow>

When i gave a relative path to my ecore, it was not able to find it. When i gave the actual path of the ecore workflow file executed. However it was not reporting any issues as it used to when there was only one ecore.

How can i be sure that it picks the correct ecore and validate?
I suppose it has something to do with same context names and same namespace. How can i resolve this?

First, there is no setter "modelFile" in type EmfMetaModel, it must be "metaModelFile".

The relative path should work when it is relative to the classpath root. Otherwise "metaModelFile" must be a URI string.

You can be sure that the right Ecore metamodel is used just by the fact that it can be located through the URI you are passing. If the file does not exist, you will notice an error.

Since your metaModel is local to the CheckComponent defined you can be sure that this EmfMetaModel instance will be another one than if you define a second CheckComponent. Each CheckComponent will use a different execution context.
