Hi,
I've deployed my backend application, based on 1.5.0-SNAPSHOT to my
jboss-4.2.2GA. I'm now starting my RCP frontend and try to load some data.
My model contains e.g.:
Entity Fault {
scaffold
- @Person caller
}
Entity Person {
scaffold
String firstname nullable
- @Address address
}
BasicType Address {
String street nullable
}
If I load a fault and call getCaller() on it, I got the following exception:
org.hibernate.LazyInitializationException: could not initialize proxy - no
Session
at
org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:57)

org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:111)

de.itemis.mitgas.stm.backend.person.richclient.data.RichPersonBase.fromModel(RichPersonBase.java:305)
at
de.itemis.mitgas.stm.backend.fault.richclient.data.RichFaultBase.getCaller(RichFaultBase.java:322)
The generated methods are:
RichFaultBase:
public RichPerson getCaller() {
if (original != null && populated == null && associationLoader !=
null) {
populated = associationLoader.populateAssociations(original);
if (populated.getCaller() != null) {
caller = new RichPerson();
caller.fromModel(populated.getCaller()); //line 322
} else {
caller = null;
}
}
return caller;
}
and RichPerson:
public void fromModel(Person model) {
original = model;
populated = null;
setAddressStreet(model.getAddress().getStreet()); // line 305
....
}
Whats wrong here? Why does the object at client side needs/knows the
hibernate sessions from the last findAll<Fault>() method call?
Could I use BasicType here?
Regards
Steffen...
