[ATL] refining problem : feature feature is not changeable [read only] [message #46833] Fri, 15 June 2007 12:26 Go to next message

hi,
i would like to transform an uml model to another one except that all
elements in imported packages from the entry model would be owned by the
root model. So the out model should not have imported package.

My problem is that in refining mode, i have noticed something which goes
wrong, the refine mode tries to modify readonly attribute and i have error
message like : feature ... is not changeable.

does someone have the same problem ?

Hi all,
since it is the first time write to this mailing list, I'll quickly
introduice myself: I'm Sebastien Revol, and I'm doing a PhD whose main
subject is the use of UML and MDE for Hardware Design.

I work with Jonathan, and we try to perform an UML to UML transfo where
only few elements are modified in the model. Therefore we thought that
the refining mode would be best-suited.
However, it seems that in this mode, when the virtual machine implicitly
copies a source element which has read-only or derived attributes, it
tries to directly modify them in the target element rather than letting
them being automatically computed by the target meta-model, and we get
the following error: feature xxx is not changeable.

Does anybody know if we do something wrong, or if there is a workaround
permitting to use the refining mode for UML models?


We tried to define a matched rule sending derived Properties on
arbitrary UML elements, but it has no effect (as if there were none of
these properties in the source element!...)

Thanks in advance,

Seb

Hello,

The refining mode is not available in ATL 2006 yet, and few new
developments are done on ATL 2004.

However, there is a technique that is very similar to the refining mode:
superimposing rules on a copy transformation. It is described on the wiki:
http://wiki.eclipse.org/index.php/ATL_Superimposition

Please, let us know if it suits your needs.


Best regards,

Frédéric Jouault
