problem with <s:convertEntity/>

[tnfink]

Hi,

I have a problem with the convertEntity-Tag. Maybe someone can help :-)

This is the XHTML-code:

 <h:selectOneMenu
 id="teamSelect"
 value="#{offerhead1.selectedTeam}"
 required="true">
 <s:convertEntity />
 <s:selectItems value="#{itemCache.allTeams}" var="team"
 label="#{team.mnemonic}"
 noSelectionLabel="Please choose.." />
</h:selectOneMenu>

The data is loaded correctly from the database and displayed on the web page. This is the signature of the bean method:

public class ItemCacheBean implements ItemCache {
 public List<Employee> getAllTeams() {
 ...
 }
}

This is the signature of the bean method for saving the selected item:

@Name(Offerhead1Bean.NAME)
@Stateful
public class Offerhead1Bean implements Offerhead1 {
 public Employee getSelectedTeam() {...}
 public void setSelectedTeam(final Employee selectedTeam) {...}
}

Now the problem is that when I select an item and submit the form the validation fails and I get the message "Value is not a valid selection."

Any ideas?

Thanks,

Torsten
