Hi all,

The "Parameter" target pattern in rule ClassToEntityComponent (see
UML2EJB.atl file) was supposed to produce a list of parameters, but it
is not working. The UML!CLASS has a composite part UML!Operation and
UML!Operation has another composite part UML!Parameter. How to reflect
this hierarchy in rule ClassToEntityComponent ? Any hint for me ?


Thanks,
-walcir
