Subject [jira] Commented: (OJB-55) Getting foreignkeyField's FieldDescriptor is failing if the foreignkey field is defined in the base class
Date Fri, 15 Jul 2005 22:27:13 GMT
    [ http://issues.apache.org/jira/browse/OJB-55?page=comments#action_12315954 ] 

Armin Waibel commented on OJB-55:
---------------------------------

Did you get any side-effects when apply your patch? If we change method  getForeignKeyFieldDescriptors()
 as you suggest OJB will return FieldDescriptor from different ClassDescriptor, these ClassDescriptor
can represent different DB tables.

Could you describe in detailed how to set up a test to reproduce your problem. This will be
really helpful.

> Hi,
>    we are using ojb in one of our application.  
> We got  the exception when we try to find the entity whos parent's foreign key field
is null.
> that is out critier will be "attr IS NULL"
> Basically getForeignKeyFieldDescriptors() method in ObjectReferenceDescriptor.java is
trying to find the foreignkeyfieldDescritpros in the current class only, thats why its giving
exception.
> If it is not available in the current class then it has to find from base class.
>  I have changed ObjectReferenceDescriptor.java -> getForeignKeyFieldDescriptors()
method. 
> i m attaching that file also.
