Ohh Sorry, I found the error.
I had an attribute in my entity without the External Type definition.
Now, I just have the original question, how can I extend the
prototypes provided for Wonder?

Hi list,
I am trying to use prototypes in my EOModel.
By default I can use the prototypes provided by Wonder via the
ERPrototypes Framework. But I want to extend them, I want to add two
more prototypes.
How can I do that?
Y tried creating an Entity named EOJDBCMyPostgresqlPrototypes, and
selecting it on my Database Config, that way I could select
prototypes from the Original EOJDBCPostgresqlPrototypes and from
mine. But When I tried to generate SQL using the Generate SQL button
I received the following exception:

I thought maybe I was wrong mixing prototypes, so I removed the
ERPrototypes Framework from my project, renamed my entity to
EOJDBCPostgresqlPrototypes and I created the prototypes I needed.
But the same exception appears once I try to generate SQL.
If I rename my entity that defines the prototypes, add the
ERPrototypes Framework and use just prototypes defined there I can
generate the sql without any problems.
Does anyone have a clue how to solve this?
Thanks in advanced.
