I have a case where a String is provided whereas a Long is expected:

Hints:
- org.hibernate.type.descriptor.sql.new BasicBinder() {...}.doBind(PreparedStatement, X, int, WrapperOptions)
-> value of X is a String (UUID)
- JavaTypeDescriptor is instanceof LongTypeDescriptor which leads to the ClassCastException when the String UUID is provided to org.hibernate.type.descriptor.java.JavaTypeDescriptor.unwrap(Long, Class<Long>, WrapperOptions)

The insert statement which is being executed:

Hibernate: insert into [pictogramlink_businessobjects] ([pictogramlink_e_id], [businessobjects_type], [businessobjects_id]) values (?, ?, ?)

Notes:
This is the linkage insert, i.e. a Graphiti Pictogram Element (legacy mode, pictogramlink_e_id) is linked to a business object from our own meta-model...
Maybe, some sort of CDOID types mismatch?

Hi Erdal,
Afaics this is a so-called anytype ereference, so the model does not explicitly define the type, it is EObject. To model
this correctly with strings you would need to add this annotation to the graphitic ecore:

@AnyMetaDef(idType =
"string",metaType = "string")
but then all your types stored in this ereference should have a string idtype.

Note that if you don't control the graphiti model then you can also use xml to define annotations:
http://wiki.eclipse.org/Teneo/Hibernate/ModelRelational/Annotations_Format#JPA_Annotations_in_XML

Or you can use an external reference, so map this ereference as an external link instead of as an anytype:
http://wiki.eclipse.org/Teneo/Hibernate/ModelRelational/Association_Mapping#Storing_external_references_.28to_non-persisted_objects.29.2C_customizing_persisting_references

Yes, I dont own the graphiti ecore, or I dont want to touch it...

I remember to avoid FeatureMaps and external refs in CDO...

So, I have to try to extend the mapping using the xml file.

I have downloaded the xsd, but not sure how to define the xml exactly.

<persistence-mapping>
	<epackage namespace-uri="http://eclipse.org/graphiti/mm">
	</epackage>
	<epackage namespace-uri="http://eclipse.org/graphiti/mm/pictograms">
	</epackage>
	<epackage namespace-uri="http://eclipse.org/graphiti/mm/algorithms">
	</epackage>
	<epackage namespace-uri="http://eclipse.org/graphiti/mm/algorithms/styles">
	</epackage>
</persistence-mapping>

Do I have to annotate the whole EPackage or just the EClass that holds the reference?

I think I found it now:

<persistence-mapping xmlns="http://www.eclipse.org/emft/teneo">
	<epackage namespace-uri="http://eclipse.org/graphiti/mm">
		<any-meta-def id-type="string" meta-type="string" />
	</epackage>
	<epackage namespace-uri="http://eclipse.org/graphiti/mm/pictograms">
		<any-meta-def id-type="string" meta-type="string" />
	</epackage>
	<epackage namespace-uri="http://eclipse.org/graphiti/mm/algorithms">
		<any-meta-def id-type="string" meta-type="string" />
	</epackage>
	<epackage namespace-uri="http://eclipse.org/graphiti/mm/algorithms/styles">
		<any-meta-def id-type="string" meta-type="string" />
	</epackage>
</persistence-mapping>

I have edited the config wiki to use a fragment instead of an additional plugin to register the xml file:

Unfortunately, that did not change anything... I have this EClass:

    <eClassifiers xsi:type="ecore:EClass" name="PictogramLink" eSuperTypes="#//PropertyContainer">
      <eStructuralFeatures xsi:type="ecore:EReference" name="pictogramElement" ordered="false"
          unique="false" eType="#//pictograms/PictogramElement" eOpposite="#//pictograms/PictogramElement/link"/>
      <eStructuralFeatures xsi:type="ecore:EReference" name="businessObjects" upperBound="-1"
          eType="ecore:EClass http://www.eclipse.org/emf/2002/Ecore#//EObject"/>
    </eClassifiers>

A table "pictogramlink_businessobjects" with 3 columns will be generated:
- pictogramlink_e_id numeric
- businessobjects_type varchar
- businessobjects_id numeric

How would I configure the xml to tell teneo to make the type of column businessobjects_id a varchar (String)?

Hi Erdal,
Are you sure that the xml file with the additional annotations is read?

Yes, cdo says that it cannot find the (graphiti) packages, but I am allowed to ignore it if the packages are registered later... And that is the case, they are registered when specific instances of the graphiti packages are serialized:

!MESSAGE No EPackage found for namespace http://eclipse.org/graphiti/mm/algorithms/styles. This is not a problem if this EPackage is registered later.

[same for other graphiti epackages]

And I have debugged down to the location where the xml file is read and parsed: org.eclipse.emf.teneo.annotations.mapper.PersistenceMappingBuilder.buildMapping(List<EPackage>, PersistenceOptions, ExtensionManager)

Hi Erdal,
Looking back at the xml, I think it is wrong, the any-metadef should be on a property/ereference not on epackage level.

This zip file contains several examples on how to do things in xml:
