Key: HB-472
Summary: Possible bug in AbstractEntityPersister
Type: Bug
Status: Closed
Priority: Major
Resolution: REJECTED
Project: Hibernate2
Components:
core
Versions:
2.1 rc1

Description:
I know I shouldn't do this, but I am calling:
ClassPersister persister = getPersister(object);
Serializable identifier = persister.getIdentifier(object);
if (persister.isUnsaved(identifier)) ...
where object is declared to have an "assigned" id generator.
in AbstractEntityPersister.isUnsaved(Object object) the following lines:
...
if ( hasIdentifierPropertyOrEmbeddedCompositeIdentifier() ) {
return unsavedIdentifierValue.isUnsaved( getIdentifier(object) );
}
...
appear wrong since the unsavedIdentifierValue.isUnsaved needs to be passed the object, not the identifier...
Basically the getter method is called on the identifier (a String in this case) and not on the object itself.
