Let's collect these. I've added one more:

The added WO Best Practice:
Rather than use
MyEO eo = new MyEO();
ec.insertObject(eo);
Prefer this form:
MyEO eo = (MyEO) EOUtilities.createAndInsertInstance(ec, "MyEO");
If this is good:
MyNewPage nextPage = (MyNewPage)pageWithName
(MyNewPage.class.getName());
then why not this?
MyEO eo = (MyEO) EOUtilities.createAndInsertInstance(ec,
MyEO.class.getName());
:-)
Good question, and one that I should add to the best practice. The
second parameter is the entity name from the model, not the class
name. For component creation it is the class name. The thing is
that entity.name != class.name most of the time. The class names in
my model include package names, but the entity names do not. Also,
I've run across cases where multiple entities in the model are
implemented by the same class. Gary Teter makes good use of this in
the WireHose frameworks.
