How to set multiple values for a property of a stereotype? [message #1863332]

Hello,

I'm wondering if we can set multiple values to a property of an applied stereotype?

I've defined a "getter" property of type Operation [1..*] on a "Property" stereotype like:

index.php/fa/43941/0/

I would like to be able to set multiple operations for the "getter" property in the Properties view of Eclipse but only one value is possible:

index.php/fa/43942/0/

Is there a way to set multiple operations?

Thanks

Oh it seems I succeeded but I had to unapply/reapply the stereotype on the element even if I had re-applied the profile on the entire package. Is it normal?

How to retrieve the first value of the Sequence in Acceleo?

On this image, we see the return type is a Sequence of Operation of size 2:

index.php/fa/43944/0/

But I can't get the first element, using asSequence()->at(1) give the same result (the 2 operations):

index.php/fa/43945/0/

And I would like to get only the first operation (getTransformation).
Is it possible?

When you use getAppliedStereotype() you fall back on the underlying Eclipse UML2 Java API rather than using the marginally specified type safe OMG navigation (prototyped and supported in the Pivot-based Eclipse OCL but not in the Classic Eclipse OCL used by Acceleo).

The non-typesafe navigation is particularly troublesome for non-unit multiplicities where the EList return is declared as, and so treated as, an Object, consequently it is quite possible that asSequence, created a Sequence of Sequence which at(1) only unwrapped once.

You should probably use as oclAsType to impose your better knowledge on the getAppliedStereotype() return. Or try flatten() to eliminate the ambiguity.
