Hi,
I have a problem with an ATL transformation. If I run only with ATL, everything works. But when I go through emftvm, I have the following error:
Exception in thread "main" org.eclipse.m2m.atl.emftvm.util.VMException: java.lang.IllegalArgumentException: Cannot add/remove OclUndefined to/from multi-valued field Model::models
at rule BlackBox2Modelica@applier#13(./transformations/concept2modelica.atl#[22:3-22:68])
Local variables: [__trace__: TRACE!TraceLink = 117e949d:TRACE!TraceLink, BlackBox: MMConcept!BlackBox = entree-sorties V2VM:MMConcept!BlackBox, Mod: MMModelica!Model = V2VM:MMModelica!Model]
at static EMFTVM!ExecEnv::main() : Object(./transformations/concept2modelica.atl)
Local variables: []
The multi-package input metamodel. I think that's where the problem comes from.
Can you help me?

You cannot close a forum topic, but perhaps you can add "SOLVED" to the topic title?
The reason you got your error before is that lazy rules type-check their input at run-time: no match means it does nothing and returns OclUndefined. Probably Collection(String) would have worked?
Cheers,
Dennis

ok Dennis. And thank you very much.
Yes I think that also.
But no, I always problem with
for(i in EQUAIN){} in "do" ancher
I show all example and I see a "do" in lazy rule to : https://wiki.eclipse.org/ATL/EMFTVM.. It's weird. ATL compiler it's ok. but not emftvm compiler for me
I put collection
just test with that and not working
unique lazy rule boxe {
from
boxe : OclAny
using {
EQUAIN : OclAny = MMConcept!Equations.allInstances();
GRAPHOUT : Sequence(MMConcept!Graph) = MMConcept!Graph.allInstances();
EQUAOUT : MMModelica!Equation = MMModelica!Equation;
LABEL : Set(MMConcept!Label) = Set{};
STATE : Set(MMConcept!State) = Set{};
VALUE : Sequence(String) = Sequence{};
NAME : Set(String) = Set{};
}
to model : MMModelica!Model(
name <- boxe.name,
interfaces <- boxe.interfaces -> collect(e | thisModule.interface(e))
)
do{
for(equa in EQUAIN){
equa.debug('test');
}
}
this code is executed with :
models <- BlackBox.box.boxes -> collect (c | thisModule.boxe(c))
And I have my debug answer but an exception :
test: V2VM_cont:MMConcept!Equations
test: V2VM_regles:MMConcept!Equations
test: V2VM_cont:MMConcept!Equations
test: V2VM_regles:MMConcept!Equations
test: V2VM_cont:MMConcept!Equations
test: V2VM_regles:MMConcept!Equations
Cannot add/remove OclUndefined to/from multi-valued field Model::models
the exception is also if I put :
....
do{
'hello'.debug('test');
}
.....
if I remove code in "do", it's ok. but I would like this code ^^
Thank
