JDO PersistenceCapable Interface for Enhanced Classes

Hallo,

in old JDO 1.0 project we use the PersistenceCapable interface like this

    Model model = new Model();
    Model datas List models = new ArrayList();
    models.add((PersistenceCapable) model);

the interface was enhanced to the class.

in the new version we get this
java.lang.ClassCastException: Model cannot be cast to javax.jdo.spi.PersistenceCapable
give it an workaround or so?

Since JDO 2.0 implementing the javax.jdo.spi.PersistenceCapable is optional, and the ObjectDB 2.x Enhancer does not implement that interface.

You should remove the casting and change your code to:

    models.add(model);
