In a Seam component, I have an array attribute with @DataModel annotation and an associated @Factory metod.

@org.jboss.seam.annotations.datamodel.DataModel
protected myPackage.VOProcessus[] listeProcessus;

@javax.ejb.TransactionAttribute(javax.ejb.TransactionAttributeType.REQUIRES_NEW)
@org.jboss.seam.annotations.Factory(value = "listeProcessus")
@org.jboss.seam.annotations.Observer("listeProcessusUpdated")
public void getListeProcessus() {
...
}

I want to test if this array is empty in a rendered attribute, so I wrote the following EL expression :

rendered="#{empty listeProcessus}"

But it looks like empty operator always returns false. I don't have this problem when I remove the @DataModel annotation.

Is this something expected or is there something I did wrong ?
