Re: [mdr-users] Problems instantiating my own metamodel

Hello Dimitrios,

Thanks, you are right. I found that when I generate the XMI using Poseidon, the
types of the attributes are deleted. It was necessary to add them manually.
Now, I can generate  the JMI interfaces succesfully.

I attach the new file of my metamodel.

Thank you for your help. ;)

Catalina
