Regarding libraries I have another question.

When I try to save a Model existing in my new user created library, I get an error for each and every model in this library unable to save.
The error message reads:

[1] 09:39:56 Scripting Error
Failed to load package SubpackageName() using MODELICAPATH Path to Library;Path to folder containing library folder.

[2] 09:39:56 Grammar Error
[Path to Packagepackage.mo: 3:1-6:10]: Expected the package to have within ; but got within Library Name;.

Perhaps I made a mistake with creating the library, altough I was working along the "Writing libraries compliant to the Modelica specification" article in the wiki.

EDIT:
I doubt there is a mistake as in Dymola demo saving of models in this library just works fine.
