Hi all, I have at first sight a basic problem, but after 2 days I didn't
even resolve it.
I am developing an HOT transformation that I want to call directly from
the weaving panel (as in qATL).
The problem is that when I try to inject ATL code into my resulting ATL
model, I get an exception (the stack trace of the
exception is attached at the end of the post).
I even tried to modify the SimpleATLtoATL.atl transformation of the
plug-in org.eclipse.gmt.weaver.qatl, but it did not work.
Notice that I modify ONLY the transformation, the source code of the
plug-in remains the same.
I modified only the following rule:
------------------------------------------------------------ -
rule InPatternElement {
from --elements of a model -- source Element
amw: AMW!InputElement
to
atl: ATL!InPattern (
elements <- element
),
element : ATL!SimpleInPatternElement(
varName <- amw.getVarName(),
type <- aType
),
-- -- creates a new model element because it may have repeated elements
aType : ATL!OclModelElement (
name <- thisModule.getLeftInstance(amw.element.ref).name,
model <-
thisModule.resolveTemp(AMW!InModelRef.allInstancesFrom('IN') - >select ( e |
true)->first(),'ametamodel')
)
}
-----------------------------------------------------------
to 'my rule':
------------------------------------------------------------
rule InPatternElement {
from --elements of a model -- source Element
amw: AMW!InputElement
to
atl: ATL!InPattern (
elements <- element,
filter <- 'true'.inject('OUT', 'ebnf2', 'ATL-oclExpression')
-- this is where the two rules differ
),
element : ATL!SimpleInPatternElement(
varName <- amw.getVarName(),
type <- aType
),
-- -- creates a new model element because it may have repeated elements
aType : ATL!OclModelElement (
name <- thisModule.getLeftInstance(amw.element.ref).name,
model <-
thisModule.resolveTemp(AMW!InModelRef.allInstancesFrom('IN') - >select ( e |
true)->first(),'ametamodel')
)
}
--------------------------------------------------------
Can anyone explain me why the injection does not work and how can I
resolve this problem?
Thanks, Ivano

Hello Ivano,
Could you please remember to prefix the subject of your ATL-related
posts to the M2M newsgroup with [ATL] as I did in this reply?
Additionally, your question may also be of interest to the AMW newsgroup
readers. Therefore, I added it in copy.
The problem you encountered seems to occur because injection of 'true'
cannot proceed. This may be because the ATL parser is not available in
the ant launch configuration classpath. You could try adding it.
Alternatively, you could also directly write the code that will create
the expression you want in the target pattern. For instance, to add 'true':
rule InPatternElement {
from --elements of a model -- source Element
amw: AMW!InputElement
to
atl: ATL!InPattern (
elements <- element,
filter <- filter
),
filter : ATL!BooleanExp (
booleanSymbol <- true
),
element : ATL!SimpleInPatternElement(
varName <- amw.getVarName(),
type <- aType
),
-- -- creates a new model element because it may have repeated
elements
aType : ATL!OclModelElement (
name <- thisModule.getLeftInstance(amw.element.ref).name,
model <-
thisModule.resolveTemp(AMW!InModelRef.allInstancesFrom('IN') - >select ( e
| true)->first(),'ametamodel')
)
}
You may not want to build your target pattern elements by just looking
at the metamodel. Then, you can write an ATL file (e.g., a query), and
inject it to see what elements you have to create.
Regards,
Frédéric Jouault

Ok, thank you, I will try to add the ATL parser to the ant classpath.
Finally, I can't directly define the code that will create the expression,
because I'd want to inject values of string attributes of my weaving
metamodel.
Thank you, Ivano

Hi Ivano,
Did you try to execute the transformation using an ATL launch
configuration, ie, outside from the plug-in?
You can do that by copying the transformation into your workspace and
setting up your input and output models as it is done for other ATL
transformations.
This would help us to verify if the problem comes from the AMW calls to
the ATL transformations or if it is a more general problem.
Regards,
Marcos.

Hi Marcos, I have just tried the modified simpleATL2ATL transformation
outside AMW and it all worked fine.
I hope it is only a configuration issue, I think that AMW does not find
ebnf injector, but it is only a hypothesis...

Hi Marcos, would you try to inject ATL code as I did (unsuccesfully :/ )?
It is a very important feature of my transformations and It still does not
work...

Hi Ivano,
the problem was that the AMW model handler did not have a modelLoader
associated with it, thus it could not load the ebnf2 injector.
I changed the code by associating an EMF model loader with the AMW model
handler. This code will be refactored later.
I tested here with these modifications and it worked well. You can check
out the amw4atl plug-in from the CVS to verify if it works for you.

Marcos.

Hi Marcos,
I finally checked out the amw4atl plug-in from the CVS and everything
worked
well, thank you very much.
I hope I will not bother you with this issues!

the code of the rules with error are in 'normal' ATL files or the code

There are two things to pay attention when developing called and lazy rules:
- in called rules, you should have a return expression at the end of the
imperative part;
- in lazy rules, the type of the input pattern should be respected.

Marcos

Hi Marcos, this is one of my rules:
rule createBinding(featName : MOF!"String", element :
ATL!SimpleOutPatternElement, var : ATL!VariableDeclaration) { -- :
ATL!Binding
to
atl : ATL!Binding(
outPatternElement <- element,
propertyName <- featName,
value <- val
),
val : ATL!NavigationOrAttributeCallExp(
name <- featName,
source <- valSource
),
valSource : ATL!VariableExp(
referredVariable <- var
)
do {
atl;
}
}
The calling of the rule works, but somewhere in the return elements goes
wrong;
in fact everything works if I remove the "to" section of the rule and I
print the input parameters in the "do" section.
I ask this to you, because I tested the same rule with the old AMW4ATL and
everything works correctly...
Do you have any suggestion?
Regards, Ivano

I didn't manage to reproduce the error here.
I will investigate it with different examples and configurations. I keep
you informed.
