Enumeration.createOwnedLiteral does not validate [message #1750085]

I am trying to programmatically add Enumeration Literals to a model within Rational Software Architect v9.1.2.2. The literals are successfully added to my model, but the model validation feature of the product flags each literal with an error:

"<Enumeration Literal> Behavioral" should contain "<Enumeration> Enumeration1" in its classifiers list.

The "Quick Fix" feature of RSA corrects each literal; it adds a "classifier" attribute to the ownedLiteral. Here is model fragment before the Quick Fix is applied:

      <ownedLiteral xmi:id="_Nx2GtMMKEea6HrNAvPVpYQ" name="Behavioral">
        <specification xmi:type="uml:LiteralString" xmi:id="_Nx2GtcMKEea6HrNAvPVpYQ" value="B"/>
      </ownedLiteral>

And the model fragment after the Quick Fix is applied:

      <ownedLiteral xmi:id="_Nx2GtMMKEea6HrNAvPVpYQ" name="Behavioral" classifier="_Ige0YMMCEea6HrNAvPVpYQ">
        <specification xmi:type="uml:LiteralString" xmi:id="_Nx2GtcMKEea6HrNAvPVpYQ" value="B"/>
      </ownedLiteral>

And here is the Java method adding an enumeration literal:

private void addEnumerationLiteral(org.eclipse.uml2.uml.Enumeration umlEnumeration, Integer literalNameIndex, Integer literalValueIndex, Integer literalDocumentationIndex, ArrayList<String> attributeFields)
{
        Comment documentation;
        List<Element> annotatedEls;
        Stereotype stereotype;
        
        EnumerationLiteral enumLiteral = umlEnumeration.createOwnedLiteral(attributeFields.get(literalNameIndex));
               
	// Add the literal value, if provided.
	if (literalValueIndex != -1)
	{
		LiteralString value = org.eclipse.uml2.uml.UMLFactory.eINSTANCE.createLiteralString();
		value.setValue(attributeFields.get(literalValueIndex));
		enumLiteral.setSpecification(value);        	
	}
		
	// Add the literal documentation, if provided.
        if (literalDocumentationIndex != -1)
        {
    		documentation = enumLiteral.createOwnedComment();
    		documentation.setBody(attributeFields.get(literalDocumentationIndex));
    		annotatedEls = documentation.getAnnotatedElements();
    		annotatedEls.add(enumLiteral);	
    		stereotype = documentation.getApplicableStereotype("Default::Documentation");
    		if (stereotype != null)
    			documentation.applyStereotype(stereotype);
        }
}

So my question is, is there an API call available to create an enumeration literal that is "valid"?

Hi,

Have a look at the InstanceSpecification::getClassifiers() API.

HTH,

Christian

Thanks, but I didn't see anything applicable. I'm really looking for something like a .setClassifier().

You add to the list returned by InstanceSpecification::getClassifiers(). This is the standard EMF idiom for manipulating multi-valued features.

Cheers,

Christian

Ah, I was making it harder than it really was. Adding this line of code did the trick:

enumLiteral.getClassifiers().add(umlEnumeration);

Thanks for your help!
