| [Acceleo 3] Calling service on list [message #557193] |

In Acceleo 2 we used to be able to call a service on a list of objects and it would execute the service on each object in the list. When I try to call the following line in Acceleo 3:
eGenericSuperTypes.genSuperClassDeclaration(eClass.ePackage)
(genSuperClassDeclaration is a service that I wrote in Acceleo 2 and is now a template I'm trying to run in Acceleo 3) this call causes an error in the higher level template:
Evaluation failed with an exception: index=1, size=1
Is this not doable anymore?
Thanks for your help in advance

Laurent,
Thanks for the idea. I tried a few things based on your suggestion. I'm not sure if the problem I'm having is exactly the same bug...
The first thing I tried was to explicitly pass the first parameter:
genSuperClassDeclaration(eGenericSuperTypes, eClass.ePackage)
When I did this I got the compile error:
illegal operation signature: (genSuperClassDeclaration(OrderedSet(EGenericType), EPackage)
Which is true because my template is defined as:
[template public genSuperClassDeclaration(eGenericType : ecore::EGenericType, currentPackage : ecore::EPackage)]
Like I mentioned before, with Acceleo 2 I used to be able to call a script on a list of objects as well as a single object and the generator would automatically call the script multiple times (once for each object in the list). If I pass in the parameter now explicitly this doesn't make sense because the parameter type is not a list, but I'm passing in a list. Is this "list type" template calling no longer possible in Acceleo 3, or do you still support it?
After this, I tried to explicitly call the template in a for loop:
[for (eGenericSuperTypes)][genSuperClassDeclaration(eClass.ePacka ge)/][/for]
This seemed to take away the error, but still didn't seem to execute correctly. Now after this template is finished the generation exits out of the [file] call and I see the following error:

Hi Tom,
As mentionned, it should work in Acceleo 3, as we did everything in
order for it to work. Yet you are in a case we didn't think of : calling
a multiple parameters query with a list of things for the first, and a
single value for the second parameter.
In short, with a query defined as :
[query public myQuery(x : Foo, y : Bar = ... /]
you should be able to call it with :
[x.myQuery(y)/]
[myQuery(x, y)/]
and thus, calling it from inside a loop on your list should work. The
other possibility is (with "sequence : Sequence(Foo)") :
[sequence.myQuery(y)/] <= automatically converted by OCL to
"sequence->collect(temp1 | temp1.myQuery(y))"
The possibility that fails because of the bug I mentionned earlier is :
[myQuery(y)/]
It will work in future versions. On the other hand, "myQuery(sequence,
y)" will never work.
Hope this clears out some of the confusion.
