DataNucleusObjectStore.loadPojo problem

[张峰昌]

Hi,Dan:

 

It seems that there are problem when to recreate an pojo with
DataNucleusObjectStore.loadPojo. The entity I have defined that use entity
itself ID which type is java.lang.Long.It’s work fine when persist the
entity,but will failed when load it to display in UI.

The failed reason is DataNucleusObjectStore.loadPojo passed an
javax.jdo.identity.LongIdentity typed value into
org.datanucleus.api.jdo.JDOPersistenceManager.getObjectById,but datanucleus
requires Long typed value.

 

 

Exception statack :

javax.jdo.JDOFatalInternalException: The key value passed to construct a
SingleFieldIdentity of type "javax.jdo.identity.LongIdentity" for class
"com.thingray.party.dom.person.Person" is of an incorrect type
("javax.jdo.identity.LongIdentity") - should be "Long".
