Re: Lifecycle listener events concerning store/delete

Hi,
It might be better to have this discussion attached to a JIRA issue. Is the test case checked in?

Hi Andy,


I'm implementing test cases for deletion by query. Assertion  
A14.8-4 specifies (amongst others) that dirty instances are flushed  
to the datastore before they are deleted.



The test case implementing this assertion adds a lifecycle listener  
to the persistence manager. The listener checks the order of events  
fired by JPOX. The test case fails if store events are fired after  
the first delete event was fired.



JPOX fires the right order of events when instances are involved  
not having any relationships. Involving instances having  
relationships JPOX does not stick to that order.


For example:


The test case updates all employees. Afterwards, it deletes these  
employees using Query.deletePersistentAll inside the same  
transaction. If the test case uses employees having relationships,  
it appears, that some store events are fired between preDelete and  
postDelete events fired on the same instance. On the other hand, if  
the test case uses employees without relationships the order of  
events meets the spec. Please have a look below.


Is the different event handling concerning relationships intentional?

Michael
