Hi,
i am trying to integrate Henshin in
a EMF-based UML tool. To test this, I am creating a rule and all of its
components programatically. I am trying to have a UML Package on the
LHS that is searched by its name. So i am trying to create an attribute
to filter by the name. I also tried naming the node but that does not
seem to have any effect. Here is my code:
lhsPackage is my Package named "myPackage".
Module module = factory.createModule();
module.getImports().add(UMLFactory.eINSTANCE.getUMLPackage());
Rule rule = factory.createRule();
module.getUnits().add(rule);
rule.setActivated(true);
rule.setName("createClassInPackage_Generated");
Graph lhsGraph = rule.getLhs(); // left-hand side of the rule
Node lhsPackageNode = factory.createNode(lhsGraph, lhsPackage.eClass(), null);
String name = (String) lhsPackage.eGet(UMLFactory.eINSTANCE.getUMLPackage().getNamedElement_Name());
lhsPackageNode.setName(name);
Attribute att = HenshinFactoryImpl.eINSTANCE.createAttribute();
att.setType(UMLFactory.eINSTANCE.getUMLPackage().getNamedElement_Name());
att.setValue(name);
lhsPackageNode.getAttributes().add(att);
However when executing the rule, I get an exception:
java.lang.RuntimeException: ReferenceError: "myPackage" is not defined in <eval> at line number 1
