I made a for loop in the main template that should print HELLO: WORLD for each class in my model using function getClasses.
The problem is that it is written only once.

GetClasses:

public Set<Class> getClasses(Model model) {
		Set<Class> classi = new HashSet<>();
		List<Type> types = model.getOwnedTypes();

		for (Type type : types) {
			if (type instanceof Class) {
				classi.add((Class) type);
			}
		}
		for(Class classe : classi)
		{
			System.out.println(classe);
		}
		return classi;
	}

MAIN:

[for(aClass : Class | getClasses(aModel))]
	[consoleMessage('HELLO', 'WORLD')/]
[/for]

RESULT:

org.eclipse.uml2.uml.internal.impl.ClassImpl@33aeca0b (name: Prodotto, visibility: <unset>) (isLeaf: false, isAbstract: false, isFinalSpecialization: false) (isActive: false)

org.eclipse.uml2.uml.internal.impl.ClassImpl@5b1f29fa (name: Ordine, visibility: <unset>) (isLeaf: false, isAbstract: false, isFinalSpecialization: false) (isActive: false)

org.eclipse.uml2.uml.internal.impl.ClassImpl@4b7e96a (name: CategoriaProdotto, visibility: <unset>) (isLeaf: false, isAbstract: false, isFinalSpecialization: false) (isActive: false)

org.eclipse.uml2.uml.internal.impl.ClassImpl@6b44435b (name: ProdottoPerOrdine, visibility: <unset>) (isLeaf: false, isAbstract: false, isFinalSpecialization: false) (isActive: false)

HELLO: WORLD

From the result is clear that the Set is properly filled but the for is not properly iterating.

Hi

It's weird but since you haven't shown us how you declared your Java for use by Acceleo it is impossible to do more than say you probably got it wrong.

This is the way i access to Java services:


[query public getClasses(arg0 : Model) : Set(Class)
	= invoke('it.mice.acceleogenerator.javaservice.ModelJavaUtils', 'getClasses(org.eclipse.uml2.uml.Model)', Sequence{arg0})
/]

This query is correctly called as you can see from "RESULT" snippet. The problem is the for iterator.
