Project overview
This feature is about adding the attribute mapping converter annotations supported by the EclipseLink JPA extension.
Goals:

- Add JPA Details view widgets for eclipselink-orm.xml convert, converter, object-type-converter, type-converter and struct-converter elements
- Provide the validation for the converters

Requirements / Functionality
Convert
@Convert annotation is supported on Basic, Id, Version, BasicMap and BasicCollection mappings
@Converter, @TypeConverter, @ObjectTypeConverter, @StructConverter will be supported on Id, Version, Basic, BasicMap, BasicCollection mappings in java. In the eclipselink-orm.xml only the convert name widget will be supported on these mappings, unless EclispeLink bug 237315 is fixed.
- Will include a twistie widget on Converters section.
- If you select Enumerated the combo box will display Default(Ordinal)
- Change generic JPA platform mappings to handle converters with radio buttons: No Converter, Lob, Temporal, Enumerated
- EclispeLink bug 237315 handles supporting converters on eclipselink-orm.xml attribute mappings.
I ran out of space, this really belongs embedded in the above panel under Object Type Mapping
- Converter, TypeConverter, ObjectTypeConverter, StructConverter supported on Entity, MappedSuperclass, Embeddable in java and in eclipselink-orm.xml. Also supported on entity-mappings element in eclipselink-orm.xml.
- On the eclipselink-orm.xml entity-mappings node support adding/removing converters. If you select a particular converter in the list then you will see that panel for that converter type. This should also be how the support works for Entity, MappedSuperclass, and Embeddable in eclipselink-orm.xml
- EclispeLink bug 241305 handles supporting multiple converters on an entity
