Hi again,
At first let me explain my problem. Basically I would like to change, add or delete a few UML objects in an UML file. Therefore I call the transformation programmatically and defined my ATL-EMFTVM transformation for a simple test as followed:
module Test;
create OUT: UML2 refining IN: UML2;
rule Class {
from
s: UML2!"uml::Class"
to
t: UML2!"uml::Class",
u: UML2!"uml::Class" (
name <- 'adsf'
)
}
I tried to get the EMFTVM Refining Mode working, but somehow get errors like
Exception in thread "main" java.lang.IllegalArgumentException: Model IN not found
at org.eclipse.m2m.atl.emftvm.impl.ExecEnvImpl.resolveRuleElementModels(ExecEnvImpl.java:1541)
at org.eclipse.m2m.atl.emftvm.impl.ExecEnvImpl.resolveRuleModels(ExecEnvImpl.java:1523)

at at.jku.uml2uml.testbench.EMFTVMLauncherTest.main(EMFTVMLauncherTest.java:24)
or when using a different rule
module Test;
create OUT: UML2 refining IN: UML2;
rule Class {
from
s: UML2!"uml::Class"
to
t: UML2!"uml::Class"(
name <- 'adsf'
)
}
this one:
Exception in thread "main" org.eclipse.m2m.atl.emftvm.util.VMException: java.lang.IllegalArgumentException: Cannot set properties of Switch:UML2!Class, as it is contained in an input model
at rule Class@applier#3(../AtlTransform/inplace/SeqClassState.atl#[15:4-15:18])

at org.eclipse.m2m.atl.emftvm.impl.ExecEnvImpl.run(ExecEnvImpl.java:2020)
Both the source and the target UML file have the same UML metamodel, but they are actually different files. Sometime I also would like to use the same file as input and output as well. Also when I use a complete empty module for the transformation, my output in the target file is simply empty.
I do not have enabled any refining mode when launching the configuration, as I thought that it is not necessary with EMFTVM anymore. I interpreted the refining mode, to actually copy unmatched elements from the source to the target model. Only if a rule is actually matched by an element in the from section, these element can be altered or even deleted. I guess I misunderstood something here, any clarification would be nice.
Thank you.
Stefan

Hi Dennis,
thanks for clearing this up for me. I followed your steps, and the transformation worked fine. As I actually launch the transformations programmatically, I changed the URI of the inout model after the transformation is done. Then I just saved it under a newly created URI.
Now it works as I thought of from the beginning, thanks again. Additionally I appreciate your and the other moderators work here in the forums as well as on the ATL project itself.
Cheers
Stefan
