Load reference Problem [message #54796] Thu, 26 July 2007 07:53 Go to next message

I' working on a transformation from AADL to HRT-UML2 under ATL.
For HRT-UML2, I use the metamodel loaded in memory while for AADL, I use the
..ecore which consists of 7 packages.
The input file of the transformation have an aael extension. It is obtained,
by a conversion under OSATE, starting from the file with aaxl extension.
The problem, that ATL does not succeed in charging the references or to
solve them.
For example in the following expression: <processImpl name= " GesVol "
compType= " #//@processType.0 "/>
when I want to get the component type, which is the comType, ATL returns an
empty list!!

Any one can help me ??

Thanks,

Hello,

First, could you prefix you subject with [ATL], next time (I did it for
that post) ? Thanks.

Then I'm not sure, but the problem seems to be in your input model, from
the compType= " #//@processType.0 " expression. Generally those kind of
references needs to indicate a filename before the #. Perhaps the
problem comes from the OSATE conversion.

In order to ensure that, could you also post the atl fragment where you
try to get that reference ?

Hello,

I thought that the problem is in the OSATE conversion, so I changed the file
extension from aael to xmi, when I open the file, I can see the referenced
objects in the Eclipse property sheet.so I estimate that the problem isn't
in the reference, but in the way that ATL resolve them ??

below is the ATL rule :

rule ProcessImpl2RCMcomponent {
from
e : AADL!ProcessImpl

to
comp : RCM!RCMcomponent (
name <- if e.name.oclIsUndefined() then 'myRCMcomponent' else
e.name + '_AP' endif,

providedTypes <- thisModule.resolveTemp(e.compType,'e')
)

do {
e.compType.debug('compType'); -- result is OCLundefined !!!
}
}

Thanks,
A AKAR

Could you provide us the aael and aaxl files ? This will really help us
to understand the problem, and to check the conversion result.

Thanks in advance,

Hello,

I test your files, and it works with the last ATL version. But when I do
the same test with the ATL bundle (available in the download section),
the debug point returns OclUndefined... so I presume that you're using
that bundle.

The problem you have may be a bug, and won't be corrected on old ATL
versions, so the best thing you have to do is to switch to ATL versions
which are available on CVS.

A guide explain how to use and install those versions :
http://wiki.eclipse.org/ATL/How_Install_ATL_From_CVS/

Best regards,

Ali,

you could try to use the metamodel uri (http:///AADL/core) as the AADL
metamodel and use the aaxl model files directly. For this to work you
need to have OSATE and ATL installed in the same eclipse instance.

Hello,

I checked out from CVS the plugins, but I can't run the transformation and I
have many events error in the Error log, here some of these errors :

>>An exception stack trace is not available.

I used two ways to work with ATL, by expoting the plugins as jar files and
by run and Eclipse application, with both I have problems.
Morover, in the Help >> About Eclipse >> Plugins details, I can't see all
the ATL plugins.

Can you tell me, which Eclipse version and EMF one you used when you tested
the aael file ??
and if possible can you send me the ATL jar files ?


Best regards

Hello,

I also tried with the last bundle version (2.0RC2), and it works too.
Could you try with this version ?
You can download the updatesite archive here :
http://www.eclipse.org/downloads/download.php?file=/modeling /m2m/atl/archivedSite/atl-ArchivedSite_2.0.0RC2.zip
Then install it in Eclipse, as an archived update-site.

Before trying it, you may have to launch eclipse with the -clean option.

Hello,

Of course, you may also directly use the update site ;-)

I don't know if the bug has been referenced in the bugzilla, but you can
consult it via the "ATL Developer Box" section in the main ATL page.

Does that answer your question?
