[Modeling-cvs] ProjectModeling/Modeling FetchSpecification.py,1.7,1.8

[Sebastien B. <sbi...@us...>]

Update of /cvsroot/modeling/ProjectModeling/Modeling
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv15040/Modeling

Modified Files:
	FetchSpecification.py 
Log Message:
Fixed bug #916019: FetchSpecification did not detect when an entity has no
ClassDescription (usually meaning either a typo or a model not loaded
yet), but assumed that one exists in setQualifier() --leading to an error
in Qualifier.validateKeysWithRootClassDescription() that was not
informative at all for the developer.
