[ATL] Applying UML profile [message #660304]

Hi all,

I'm trying to apply a UML profile and stereotype to a UML sequence diag. giving my profile (Pro) as input model. But it raises this error:

org.eclipse.m2m.atl.engine.emfvm.VMException: Operation not found: OUT!CustomerInterface.getStereotype(java.lang.String)
at __applyLifeline#19(transApplied2.atl[40:22-40:49])

The ATL file:
module transApplied2;
create OUT : UML from IN : UML, Pro : UML;

helper def : getStereotype(name : String) : UML!Stereotype =
UML!Stereotype.allInstancesFrom('Pro')->select(p | p.name = name)->first();

rule Model {
from
s : UML!Model
to
t : UML!Model ( name <- s.name)
do {
t.applyProfile(UML!Profile.allInstancesFrom('Pro')->select(p | p.name = 'seqProTest1')->first()); }
}

rule Lifeline {
from
s : UML!Lifeline
to
t : UML!Lifeline (name <- s.name)
do {
t.applyStereotype(t.getStereotype('optional'));
--t.applyStereotype(t.getApplicableStereotype('seqProTest1:: optional')); }
}

Does anyone know why it couldn't find the operation getStereotype.

Thanks in advance,

Sally

The helper getStereotype is defined without context so to call it you have to use "thisModule" :
thisModule.getStereotype(str)

Thanks Sylvain. I still get the same error that "operation not found"

Hi,
Your passing a UML!Stereotype into getStereotype(name : String) when the helper expects the stereotype name. This means ATL won't find a helper matching your signature.

Hi,
I modified to
t.applyStereotype(thisModule.getStereotype('optional'));
where optional is the stereotype name

I get this error
Operation not found: OUT!CustomerInterface.applyStereotype(org.eclipse.m2m.atl.en gine.emfvm.lib.OclUndefined)

The profile is correctly applied to the model, the problem with the operation applyStereotype.

I appreciate any hint.

Sally
