[gme-users] quesion of lesson 2

[Lizhe WANG]

Hi, 
I 'm new to GME and try the tutorials. 
When I tried lesson 2, I built the meta model same as shown in Fig 2.1
However, when I interpreted it, the output is:

=================================================== 
Note: Aspect mapping avoided. No user choice needed to be made. 
Duplicate role line found: 

Network of kind Network in model NetDiagram. Details of the 2nd role
following: Not Inherited Role, Long form, Is Not Port, Cardinality: 0..*
Not dumping twice. 
Please check the metamodel for duplicate roles. 
Duplicate part found. Not dumping twice: 
END OF LOG


Can anyone help?

Thanks, 
Lizhe
