[ATL] reference model elements of other rules [message #99019]

Hello,

I have a refinement transformation for 2 input and output models (with
different meta-models). One of the models has to reference a model element
of the other model that is created in the same transformation. Consider
the following example:

rule Rule1 {
from i : MM1!ModelElement1
to o : MM1!ModelElement1
(
attribute <- attribute1
),
attribute1 : MM1!ModelElement2
(
stringAttribute <- 'aString'
)
}

rule Rule2 {
from i : MM2!ModelElement2
to o : MM2!ModelElement2
(
attribute <- ??? -- should reference the model element "attribute1" of
Rule1
)
}

Is there a solution for this problem? I tried to use the resolveTemp()
function, but it did not work...

Best regards,
Michael

Normally you should use resolveTemp did you use like this ?

attribute <-
thisModule.resolveTemp(myHelperGettingTheElementTypedMM1!Mod elElement1,'attribute1')

becareful with your rule it matches MM1!ModelElement1 so you should get
the element in any case by a helper maybe :
MM1!ModelElement1.allInstances()->select(...)

Thanks Tristan! That's what I needed. I haven't thought of the helper to
get the MM1!ModelElement1.
