Having a node creation tool with a "Select Model Element Variable" displaying objects in tree and executing this creation tool give the following exception :

Created attachment 258680 [details] Metamodel Projects
Created attachment 258681 [details] VSP
Created attachment 258682 [details] Project to reproduce Steps to reproduce: 1. Import in a first Sirius instance Bug484382_MetamodelProjects.zip to have metamodel 2. Import in a second Sirius instance, having the metamodel projects, Bug484382_VSP.zip to have odesign 3. Launch a third Sirius instance 4. In this third instance import Bug484382_ModelingProject.zip 5. In the imported Modeling Project, open the diagram, use the creation tool and click on diagram => KO we get the exceptions of previous comment. This occurs because of mistakes in "Select Model Element Variable" children expression, i.e. "aql:self.eContents(aqlbug.A)->union(self.eContents(aqlbug.Package))", use incorrect qualified name for EClass. We can notice an inconsistency in Sirius qualified name, for example in domain class field, we use dot notation while in aql expression we use "ePackageName::eClassName". Using ""aql:self.eContents(aqlbug::A)->union(self.eContents(aqlbug::Package))" expression, the validation give an not understandable message : Nothing left after union: Nothing will be left after calling eContents: EClassifier=A cant contain EClassifierLiteral=A direclty Nothing will be left after calling eContents: EClassifier=A cant contain EClassifierLiteral=Package direclty
