compilation problem in repository rule

[tombrus]

I have the following repository rule:

attr set<node<X>> allX := this.modules.allX;

this is correct dclare code but generates incorrect java code:

      public Iterable<SNode> translate(SModule e) {
        return DclareUtil.<DModule,Set<SNode>>getAttributeValue(Module_BASE.ATTR_X_0, e);
      }

The type of e is SModule where a DModule is expected. The following cast should be inserted since e can always be cast here:

      public Iterable<SNode> translate(SModule e) {
        return DclareUtil.<DModule,Set<SNode>>getAttributeValue(Module_BASE.ATTR_X_0, (DModule) e);
      }
