Since you are using 3, you can create a callback in Cayenne Modeler.
When you select the ObjEntity (the Java portion) in CM, there is a
Callbacks tab. Click on it and add a "post-add" callback. You can
call it "initialize" or "initializeProductType" or something similar.
Then in your .java file, create a method like:
protected void initialize()
{
setFoo(3);
}
You can look at this page for more information on callbacks (including
types of callbacks you can register):
