    Thank you for your fast reply (wow!! :-)

    Yes the things are very basic and may be I am too
    stupid (hopefully not, so that I will not waste your
    time ...)
    Mike Kienenberger, I tried it with
    SimplePerson p =
    (SimplePerson)context.createAndRegisterNewObject(SimplePerson.class);

    and have the same problem...

    Now, I will start a new SimplePerson "project" from
    the scratch to figure out where the problem
    comes from. Which database do you use?

    Here is the generated source:
    _SimplePerson.java
    package test;
    import org.objectstyle.cayenne.CayenneDataObject;
    /**
     * A generated persistent class mapped as
    "SimplePerson" Cayenne entity. It is a good idea to
     * avoid changing this class manually, since it will
    be overwritten next time code is
     * regenerated. If you need to make any
    customizations, put them in a subclass.
     */
    public class _SimplePerson extends CayenneDataObject {
        public static final String MYINT_PROPERTY =
    "myint";
        public static final String NAME_PROPERTY = "name";
        protected Integer myint;
        protected String name;

        public Integer getMyint() {
            if(objectContext != null) {
                objectContext.prepareForAccess(this,
    "myint");
            }
            
            return myint;
        }
        public void setMyint(Integer myint) {
            if(objectContext != null) {
                objectContext.prepareForAccess(this,
    "myint");
            }
            
            Object oldValue = this.myint;
            this.myint = myint;
            
            // notify objectContext about simple property
    change
            if(objectContext != null) {
                objectContext.propertyChanged(this,
    "myint", oldValue, myint);
            }
        }
        
        public String getName() {
            if(objectContext != null) {
                objectContext.prepareForAccess(this,
    "name");
            }
            
            return name;
        }
        public void setName(String name) {
            if(objectContext != null) {
                objectContext.prepareForAccess(this,
    "name");
            }
            
            Object oldValue = this.name;
            this.name = name;
            
            // notify objectContext about simple property
    change
            if(objectContext != null) {
                objectContext.propertyChanged(this,
    "name", oldValue, name);
            }
        }
    }

    SimplePerson.java:
    package test;
    /**A persistent class mapped as "SimplePerson" Cayenne
    entity. */
    public class SimplePerson extends _SimplePerson {
    }

    Bye, Peter.

    PS: Another problem occured if I choose "generator
    version = 1.1" in the class generator
    dialog _SimplePerson.java will be:
    ${importUtils.setPackage($entityUtils.superPackageName)}${importUtils.addReservedType("${$entityUtils.superPackageName}.${entityUtils.superClassName}")}${importUtils.addType("${entityUtils.basePackageName}.${entityUtils.baseClassName}")}${importUtils.generate()}
    /**
     * A generated persistent class mapped as
    "${objEntity.name}" Cayenne entity. It is a good idea
    to
     * avoid changing this class manually, since it will
    be overwritten next time code is
     * regenerated. If you need to make any
    customizations, put them in a subclass.
     */
    public class ${entityUtils.superClassName} extends
    ${entityUtils.baseClassName} {
    }
