Hi all,
I've written a basic transformation in ATL.
When I run atl file, classes of model are hidden.
I've the following result

****** BEGIN Stack Trace
message: cannot find metamodel element PAstep in model UMLbase
A.main() : ??#22 null
local variables = {self=Uc2Ft : ASMModule}
local stack = []
A.__initallClassesUC() : ??#6 5:52-5:66
local variables = {self=Uc2Ft : ASMModule}
local stack = [Uc2Ft : ASMModule, Sequence {}]
****** END Stack Trace

Have anyone an idea for this problem?

Thanks

Luciana

Hi Luciana,

Typically, this error occurs when you try to acces an element whose
class is not in the metamodel.

From the stack trace, it seems to appear in the "allClassesUC"
attribute (which cannot find a PAstep element).

Hi Quentin,
in my metamodel there is the Pastep class, but the class is not read.
How can I make it see? Where can the error be?

Thank you

Hi,

I think I foresee your problem: It seems that you are using the profile
for scheduling, right?

In this case, first, make sure you are using the UML model handler.

Then, as the ATL VM does not handle the stereotyped metaclass as whole
metaclass (it only deals with the base metaclass), you should refer to
the base metaclass and the make sure it has been applied the stereotype.

Regards,

Quentin

This one more for the [ATL] subject prefix.

(One of the good practices I forgot in my previous answer ;) )

Hi,
Yes, I'm using the profile for scheduling.
How I do to see if I'm using the UML model handler?
In Run configuration, Path Editor section, I've that
model handler is EMF. Is it all right?

Thank you very much.

Hi,
I haven't the possibility to swich to UML2,
because the two choices are: EMF and MDR.
How can I load the model handler UML2?
Is there a way?

Thanks, thanks, thanks

Hi

Can you please check that you have the latest version of ATL and that
you have the UML2 plugin installed ?
This should solve the problem.

Hi,
I have installed the ATLBundle_20070217.zip available from the site of
Inria.
Here, there are plug-in UML2 version 2.0 and ATL version 1.0.
Are they all right or there are new version?

Thanks

Hi,

Indeed, this one is outdated. I advise you to get a new eclipse and to
install ATL from the update site.
http://www.eclipse.org/m2m/atl/download/

(Don't forget to install the EMF and UML2 plugins also.)
