Visual Web JSF. Problem with the prerender() method.

There is a non clear paragraph. This is what I am meaning,



My problem is the first time I select a Subcategoria from its

DDL. productosDD is a nested Producto DDL son when I select a Categoria and a Subcategoria the DDL Producto is loaded with a subset

of data of the table Producto. Well, when I select a Categoria and a Subcategoria it loads Producto and I get the first Item of the Producto DDL. Later I calculate the firstProductoId and idPieza and I hope that piezaDataProvider refresh with the new calculated values and my table show the new rows. But it does not work. And it does not only for the first time. The rest of the time the web app works ok.



Excuese my english,
