[jboss-user] [JBoss Seam] - Error selecting object problem

[jamesjmp]

hi,
In a form I´ve a h:selectOneMenu which is filled according to the values of a List.


  |                 <s:decorate id="firmCodeDecoration" template="layout/edit.xhtml">
  |                     <ui:define name="label">#{messages['Firm']}</ui:define>
  |                     <h:selectOneMenu value="#{rstReportHome.instance.firm}" required="true" id="firm">
  |                         <s:selectItems value="#{firmList.resultList}" var="firm" label="#{firm.firmCode}" />
  |                         <s:convertEntity/>
  |                         <a:support event="onchange" reRender="firmCodeDecoration"/>
  |                     </h:selectOneMenu>                
  |                 </s:decorate>

Component firmList is seam-gened with just a simple query this way:

  | 	@Override
  | 	public String getEjbql() {
  | 		return "select firm from Firm firm";
  | 	}

I want in my selectOneMenu to display all the values of table Firm, but I do want an extra value as well. 
Let´s call it "Automatic".
I´ve added the following to component firmList:


  |         @Override
  |         public List<Firm> getResultList() {
  |             System.out.println("firmList getResultList!!");
  |             Firm auto = new Firm();
  |             auto.setFirmCode("AUTOMATIC");
  |             CfgCurrency cfgCurrency = new CfgCurrency();
  |             cfgCurrency.setCurrencyCode(60);
  |             auto.setCfgCurrency(cfgCurrency);
  |             List<Firm> firmas = new ArrayList<Firm>();
  |             firmas.add(auto);
  |             firmas.addAll(super.getResultList());
  |             System.out.println("firmas.size: "+firmas.size());
  |             return firmas;
  |         }
  | 

After adding this, selectOneMenu  displays AUTOMATIC value as well as the rest retrieved by the query. 
But when I press a button that performs persist() ajax validation displays red message besides with "Error selecting object" only If I choose Automatic option.
I guess it must be something related with s:convertEntity, but I´m not sure how to tackle it.

This is firm object:


  | @Entity
  | @Table(name = "FIRM", catalog = "prisk")
  | public class Firm implements java.io.Serializable {
  | 
  | 	private String firmCode;
  | 	private CfgCurrency cfgCurrency;
  | 	private String firmDescription;
  | 	private Set<RstReport> rstReports = new HashSet<RstReport>(0);
  | 	private Set<Fund> funds = new HashSet<Fund>(0);
  | 
  | 	public Firm() {
  |                 firmCode = "";
  |                 firmDescription = "";
  | 	}
  | 

What is the best way to add an extra value (apart from those provided by the query) to be displayed in a selectOneMenu?
If overriding getResultList is one of the ways, why I´m having that validation problem?
thanks in advance!
