Subject [jira] [Commented] (OPENJPA-2505) OpenJPA PersistenceException: LongId cannot be cast to MyEntityClass… @OneToMany in combination with FetchType.EAGER
Date Wed, 23 Jul 2014 16:53:39 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-2505?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14071948#comment-14071948
] 

Marc Logemann commented on OPENJPA-2505:
----------------------------------------

any news on that?  i am a colleague of Martin and most likely i am on the same spot as Martin.
I also tried various things w/o success to solve / circumvent it. Currently i am on 2.2.0.


Any ideas how to workaround this?

> Further information:
>     My jpql: select p from Parent p
>     If I change the FetchType to "LAZY" (or leave it just out) I got my result normaly
and the children object (the list) is null of course, but if I call the getter of the list
now (in the transaction), the object will be filled normaly without this exception.
>     Furthermore this exception does not occur when I have just 1 parent with child objects.
I can have several parents and children in my tables, but when more than 1 parent have children
referenced in the database, this exception will be thrown.
>     Also if I change the type of "oid" from "long" to "int" the exception will change,
too: "...LongId cannot be cast... -> ...IntId cannot be cast..."
>     I used: Java 8 with jpa 2.1.0 and 2.2.2, Java 6 with jpa 2.2.2
>     MySQL Database
