Hi!

I'm facing a problem when I try to save the joined subclass Projectartifacttype.
The Projectartifacttype VO extends the Artifacttype VO. To save the Projectartifacttype, I have to set the Artifacttype properties (id, name and description) with values of an existent Artifacttype row.
After that, I call the save method to the Projectartifacttype VO. this method inserts a new row in the Projectartifacttype table and in the Artifacttype table.
The problem is that I only want to insert a new row on the Projectartifacttype table and not on the Artifacttype.

What do I have to do to avoid the automatic insert on the Artifacttype table?

Thanks for the help!
