[news.eclipse.rt.eclipselink] Use Transformer in query

[jandam@xxxxxxxxxx (Martin JANDA)]

Please can you help me.

I have "Param" object with read+write transformer. And I want to map 
"Columns" to "attributes" because I want to sort/select "Items" according 
to Column "FREQ", "TYPE", ...

JPQL query: "select o from Items as o order by o.param.freq"
 Thank you very much.

..
class Items {
..
   @ReadTransformer(transformerClass = Param.class)
   @WriteTransformers({
           @WriteTransformer(transformerClass = ParamType.class, column = 
@Column(name = "TYPE")),
           @WriteTransformer(transformerClass = ParamDouble.class, column 
= @Column(name = "FREQ", precision = 8, scale = 0)),
           @WriteTransformer(transformerClass = ParamDouble.class, column 
= @Column(name = "FREQ_LO_LIMIT", precision = 8, scale = 0)),
           @WriteTransformer(transformerClass = ParamDouble.class, column 
= @Column(name = "FREQ_HI_LIMIT", precision = 8, scale = 0))
   })
   private Param param = null;
