kk commented on METAGEN-71:
---------------------------
The problem I described is part of a much larger system and it would be
very difficult (and timeconsuming) to make a small testcase.
Maybe you can use an existing testcase and alter it slightly.
My problem boils down to this:
- If you have an emmbedded object in a superclass the you get the error when
"Ejb3Configuration.buildEntityManagerFactory ()" is called.
I'll debug a little further and see what more information i can give.
Metamodel check fails when subclasses are used
----------------------------------------------
Key: METAGEN-71
URL:
http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-71
Project: Hibernate Metamodel Generator
Issue Type: Bug
Components: processor
Affects Versions: 1.1.1.Final
Reporter: kk
Assignee: Hardy Ferentschik
Fix For: 1.2.next
Situation:
Class 'AbstractIntake' which has the field 'm_startDate'
Class 'Intake' extends 'AbstractIntake'
In Class 'AbstractIntake_.java" there is the line:
public static volatile SingularAttribute<WorkOrder, MESDateField> m_startDate;
'm_startDate' is of type MESDateField which is an Embeddable object.
Result:
I get the following error when the metamodel is checked:
Unable to locate static metamodel field : gti.domain.Intake_#m_startDate
Expected:
'Intake_' subclasses 'AbstractIntake_' and therefore has access to the
static variable 'm_startDate' (in AbstractIntake_). The errormessage is
therefore not valid!
Hints:
MESDateField is an Embeddable object.
It seems to only to go wrong with Embeddable objects.
Maybe the problem is in "MetadataContext.registerAttribute()'.
There ONLY the getDeclaredField(name) of the class is checked but NOT the
subclasses of that class!
