[great-users] Can't run UMT interpreter due to library

[Gabriele Trombetti]

Hi all,
We have a big metamodel with a library inside (that is, readonly). In 
the new version of the metamodel there is a new version of the library. 
When I open the new metamodel in GME and I run the UMT interpreter, it 
fails, because as it seems it needs to modify the metamodel, and also 
the parts which are in the library (which are readonly).

I don't understand why the UMT interpreter needs to change the 
metamodel... why should it? If somebody can explains us why this is 
needed, and which types of changes it performs, we probably can think of 
how to work around the problem.

We could flatten our metamodel so that it does not contain a library 
anymore, but we would anyway like to know how the UMT interpreter 
modifies it. Our metamodel is so big that it would be impossible to find 
what exactly has been changed by the UMT...

Thanks
Gabriele
