[hibernate-issues] [Hibernate-JIRA] Commented: (METAGEN-71) Metamodel check fails when subclasses are used

[kk (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/METAGEN-71?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=42997#comment-42997 ] 

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.

> 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!
