### Are you willing to submit a pull request?

No

Start with org.netbeans.modules.j2ee.persistence.wizard.jpacontroller.JpaControllerGenerator.java around line 248 and the JpaControllerIterator flow. Reproduce the JPA controller wizard using an entity class and inspect why derivedIdGetterElement is null. Done means the controller is generated with its methods and no RequestProcessor NullPointerException occurs.
