    1. COThis seems to be wrong: value="{#programMB.np}". You should have the # before braces

    2. COIf `vehiculedao.getAll()` returns an empty list, why exactly do you think that the problem is in JSF side? Isn't it more logical that the problem is actually in the code behind that `getAll()` method? All that JSF code is then pure noise and you should rewrite the question in such way that it's asked in Hibernate context.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
