Hi,

When I use two variables in the "from" action I obtains an exception.

My metamodel is "UML1.3"

<<<<<<<<<<<<<<<<<

rule statemachine{
from
stateMachineIn : UML!StateMachine,
contextClass : UML!Classifier--(stateMachine."context"=contextClass)
-- When I add "contextClass" as variable I would have the
exception

to
stateMachine : UML!StateMachine(
namespace<-stateMachineIn.namespace
)
do{

}
}
<<<<<<<<<<<<<<<<<<

The exception code :

Hi,

This is so because the pattern you use to match contextClass is using a
reference to itself. In your case, I guess you are trying to make
reference between matched objects for a multi class pattern. This can be
done by using the binding alias in the definition of the pattern.

Hi,

Can you please tell us, which version of ATL (2004 or 2006) you are using?

Note that ATL 2004 does not support multiple source pattern elements.
This may be the cause of the error you get.

Frédéric Jouault

Hello,

> I use the version of "Septembre 16, 2005"

I am a bit confused.

Do you mean you try to use ATL 2006 with a build dating from September 2005?

Even if you put
-- @atlcompiler atl2006
at the beginning of your transformation, ATL 2006 will not be used,
because it did not exist at that time.

You should probably install a new version (e.g., 2.0RC2, available from:
http://www.eclipse.org/m2m/atl/download/).

Frédéric Jouault
