Hello,

Looking to the XMI, it is very often difficult to see exactly where errors are coming from.
A good advice when developing transformations or more generally working with models: you should rather open your models into regular model editors such as the MoDisco Model Browser.

Concerning UML profiles/stereotypes and ATL, you can find good complementary information from this page.

I hope this helps.

s.getAppliedStereotypes().first().debug('xx');
the result is: <unknown>!PaStep.
host is ereference of PaStep in marte metamodel and I can know that the host connect to another stereotype GQAM:GaExecHost ,but the expression that s.getAppliedStereotypes().first().host.debug('YY');is error.
the error is :Feature host does not exist on Stereotype.
Why?

I just want to know that how to get another stereotype or element by the reference of a stereotype of a element ?
"Feature xx does not exist on Stereotype" appears in console.
I've spent three days to solve this problem, but still did not solve this problem.
Thank you vey much !

Hello,

I guess your problem is not coming from ATL but from the current knowledge you have of the UML2 metamodel.

Whe doing s.getAppliedStereotypes()->first() (by the way, you have to use the "->" operator because the called method is returning a sequence and not a single element) you get a model element of type UML2::Stereotype.
You should take a look to the UML2 metamodel so see the actual features of this type of element, but "host" is probably not one of them. Normally, a stereotype rather provides a set of tagged values that you can access by knowing the corresponding tags.
I hope this helps.

Best regards,

Hugo

Dear Hugo Bruneliere,
In my project ,I apply MARTe profile to UML model."host" is not a feature of UML2::Stereotype in UML2 metamodel,but "host" is a feature of PAM::PaStep in MARTE metamodel . The relationship of two model elements was achieved by their corresponding stereotypes.In ATL rule ,I need to get the relationship of two model elements to generate reference.
How can I do ?

In Papyrus ,I bulid a deployment diagram and activity diagram .The action of activity diagram was deployed to a server device of deployment diagram .
Action has a "PAM::Pastep" and the value of "Host" is the name of corresponding server device.In ATL rules ,I need to get the reference of them to generate reference for my target model element .
Can you give me some suggestion?
Thank you !
