Hi everybody,

I'm having a problem at the moment to assign the element namespace to
package element within the rule ATL, for example, set so the ATL rules
with uml1.4:
rule MergePackage {
from s : UML2!Package
to t : UML2!Package mapsTo s (
name <- s.name,
namespace <- s.namespace
)
}

But now the rules ATL with uml2 (version 1.0) can not assign.

Someone could help me, please?

Hi Carlos,

ATL can't match the namespace<-s.namespace statement because in the UML
2.0 metamodel, the namespace feature is derived, hence you can only read
it and not write it.

If you want match the package namespace, you must use the
s.owningPackage feature which is a subset of the namespace set.

Best regards

Frédéric

Hello Frédéric, thank for your attention.

I changed to the feature owningPackage, but there was the error that does
not exist on UML2! Package.:
****** BEGIN Stack Trace
message: owningPackage feature does not exist on UML2! Package

I am using this API: eclipse-uml2-1.1.1.jar.

I have the same problem for other elements (Class, Property ,...), the
rules ATL have that to inform the namespace of each element, that is, who
owns the element.

Frédéric, you can help me! Very grateful.

Hi cralos,

I have not tried yet but if the "s.owningPackage" doesnot work, the
"s.nestingPackage" should (this is also a subset of the namespace feature).

To solve such problem by your own, you have just to look at the "package
" metaclass description in the UML2 superstructure.
