Data binding in table

Using table I define a datasource with my objects:
BeanItemContainer<Ordini> dataCont = new BeanItemContainer<Ordini>(Ordini.class, ordini);
Ordini contains another object (Articolo) where is the description I want to see in the table but... using
table.setVisibleColumns(new Object[] { "artior", "artiDesc", "colord", "unitaMisura", "qtaord", "qtaspo", "saldo" });
I cannot do in place of "artDesc" the navigation to the object contained in Ordini i.e "articolo.desc".
There are some tips for doing that?
Thanks
 

Hi, try this:

dataCont.addNestedContainerProperty("articolo.artiDesc");
table.setVisibleColumns(..., "articolo.artiDesc", ...);

Hope that helps.

I've tried your solution but...
Ids must exist in the Container or as a generated column, missing id: articolo.mtDesc
is the response of vaadin.
This is what I do:
BeanItemContainer<Ordini> dataCont = new BeanItemContainer<Ordini>(Ordini.class, ordini);dataCont.addNestedContainerProperty("articolo.mtdesc");dataCont.addNestedContainerProperty("articolo.mtunmi");
......
table.setContainerDataSource(dataCont);.......table.setVisibleColumns(new Object[] { "artior", "articolo.mtDesc", "colord", "articolo.mtunmi", "qtaord", "qtaspo", "saldo" });
 

Maybe the problem is only a typo: you defined the nested property as articolo.mtdesc but the visible column is articolo.mtDesc (with uppercase d charcter)

My God, you are right!!!!
Thanks a lot
