With a metamodel defining 3 concepts : 1. Package to contains following concepts 2. A 3. B subtype of B I want a diagram to display only A instances, then I define a Mapping with 'A' as domain class and with a precondition to only accept instances whose real type is 'A' but not 'B'. But AQL doesn't accept that, for AQL it is a tautology.
Created attachment 258617 [details] Metamodel Projects Steps to reproduce: 1. Import in a first Sirius instance Bug484217_MetamodelProjects.zip to have metamodel 2. Import in a second Sirius instance, having the metamodel projects, Bug484217_VSP.zip to have odesign 3. Validate the odesign => KO I get 3 error markers : - Always false - Always true - ErrorEnumLiteral This seems caused by precondition of "AMapping", i.e. "aql:self.oclIsTypeOf(aqlbug::aqlbug::A)" because I want view created only for instances of 'A' but not for instances of 'B' 4. Remove this precondition and launch a third Sirius instance 5. In this third instance import Bug484217_ModelingProject.zip 6. In the imported Modeling Project, open the diagram, we can see 2 nodes, one for a 'A' instance and the second for a 'B' instance. 4. Now clause this third Sirius instance and come back to the odesign to set the precondition as before, i.e. "aql:self.oclIsTypeOf(aqlbug::aqlbug::A)" 5. Restart the third Sirius instance and open the diagram => KO : java.lang.NullPointerException at org.eclipse.acceleo.query.parser.AstEvaluator.caseEnumLiteral(AstEvaluator.java:295) at

In fact the problem, the errors marker don't helps, comes from "aql:self.oclIsTypeOf(aqlbug::aqlbug::A)" expression where "aqlbug::" prefix appears twice. This occurs because of a bug in qualified name completion. Indeed when typing aqlbug:: and using completion with Ctrl+Space and choosing "A" EClass, I have "aqlbug::aqlbug::A" instead of "aqlbug::A"
The tautology issue should be addressed in the following review: https://git.eclipse.org/r/#/c/65487/
