Hi All,
 I am trying to specify DirectToFieldMapping, OneToMapping and OneToManyMapping in the session customizer.

 Let's take a example of OneToOneManyMapping . I am setting up the OneToOneMapping as follows. Currently I am specifying "do not use indirection". Is it possible to specify - IndirectionPolicy and make sure the relationship uses ValueHolder (lazy initialization). I will be great if somebody can point me to sample code to achieve this.I want to programatically weave in the lazy loading value holder code.

    private void oneToOneMapping(ClassDescriptor classDescriptor) {
        OneToOneMapping _oneToOneMapping_ = new OneToOneMapping();
        oneToOneMapping.setDescriptor(classDescriptor);
        oneToOneMapping.setCascadeAll(true);
        oneToOneMapping.dontUseIndirection();
       
        VirtualAttributeAccessor virtualAttributeAccessor2 = new VirtualAttributeAccessor();
        virtualAttributeAccessor2.setAttributeName("phoneNumber");
        virtualAttributeAccessor2.setGetMethodName("get");
        virtualAttributeAccessor2.setSetMethodName("set");
        virtualAttributeAccessor2.initializeAttributes(classDescriptor.getJavaClass());
       
        oneToOneMapping.setAttributeAccessor(virtualAttributeAccessor2);
        oneToOneMapping.setAttributeName("phoneNumber");
        oneToOneMapping.setReferenceClass(PhoneNumber.class);
        oneToOneMapping.setForeignKeyFieldName("PHONE_NUMBER_ID");
       
       
        Vector

databaseFields = new Vector(); databaseFields.add("PHONE_NUMBER_ID"); oneToOneMapping.setForeignKeyFieldNames(databaseFields); classDescriptor.getMappings().add(oneToOneMapping); } Another question ============= Is it possible to specify Reader/WriterTrasnformer with VirtualMethods. That is, to apply Reade/WriteTransformer to the attributes in the extension Map. NOTE > In my use case, extension attributes can be DirectToFieldMapping/OneToOne/OneToMany attributes which I am making it programatically in the session customization phase. ~GM
