I have found an issue with implementing the _object member as a
SequenceHashtable. In one of my objects I override the hashCode method. For
some reason that was wrecking havac with the object lookup. Castor kept
throwing the following exception, IllegalArgumentException("ObjectEntry to
be rehash is not found!") in org.exolab.castor.persist.TransactionContext.
Does anyone have any ideas why? I guess my hashcode is not valid. Should I
also override the equals method.
public int hashCode() {
return ( ((this.ipAddress == null)? "" : this.ipAddress )
+((this.hostName == null)? "" : this.hostName )).hashCode();
}
