Seam/JSF thinks action method to be property...
Hi,
I've got a list of data which I want to be able to apply filters to. That is,
I put a combobox on top with a submit button. This shall render the list
using a new query:
<?xml version="1.0" encoding="ISO-8859-1" ?>

The interesting part is in the first <h:form>.
The bean looks like this:
@Stateful
@Scope(ScopeType.SESSION)
@Name("listVertraege")
@Interceptors(SeamInterceptor.class)
public class ListVertragActionBean implements ListVertragAction {
private static final Category _logger = Logger.getInstance(ListVertragActionBean.class);
private static final long serialVersionUID = 1L;
@DataModel(value = "vertraege")
private List<Vertrag> _vertraege;
@Out(required = false, value = "vertrag")
@DataModelSelection
private Vertrag _vertrag;
@SuppressWarnings("unused")
@Out(value = "vertragReadOnly", required = false)
private Boolean _vertragReadOnly;
@PersistenceContext(type = EXTENDED)
private EntityManager _em;
private VertragsFilter _vertragsFilter = new VertragsFilter(VertragsFilter.ALLE);
@SuppressWarnings("unchecked")
@Factory("vertraege")
public void findVertraege() {
// TODO: Use chosen filter
_vertraege = _em.createQuery("FROM Vertrag v ORDER BY v.vertragsBeginn").getResultList();
}
public String select() {
return "selected";
}
public String delete() {
_logger.debug("Löschen des Vertrags: " + _vertrag);
_vertrag.removeAllVertragspartner();
_vertrag.removeAllPatient();
_vertraege.remove(_vertrag);entfernen
_em.remove(_vertrag);
_vertrag = null;
return "deleted";
}
public String edit() {
return rereadAndEdit(false);
}
public String end() {
return rereadAndEdit(true);
}
private String rereadAndEdit(boolean readonly) {
_vertragReadOnly = readonly;
_em.refresh(_vertrag);
return "editVertrag";
}
public VertragsFilter getVertragsFilter() {
_logger.warn("getVertragsFilter: " + _vertragsFilter);
return _vertragsFilter;
}
public void setVertragsFilter(VertragsFilter vertragsFilter) {
_logger.warn("setVertragsFilter: " + vertragsFilter);
_vertragsFilter = vertragsFilter;
}
public String filter() {
_logger.warn("filter: " + _vertragsFilter);
return "hallo";
}
@Remove
@Destroy
public void destroy() {
_logger.debug("Bean wird entfernt: " + _vertrag);
}
}
But this gives me the following exception:

Why does he possibly think the "filter" is property? I understand the he
wants to call a method getFilter() and there is none. But why is that?
I have seen similar code in the examples and it works.
I tried to use just one form or commandButton, but that doesn't work either.
Puzzled
