[jboss-user] [JBoss Seam] - Re: SeamSelectItems - 1.1.1beta4

[MikeDougherty]

in home.xhtml:

  |     <h:form id="selectSubject">
  |       <h:selectOneMenu value="#{subject}">
  |         <si:selectItems value="#{subjects}" var="s" label="#{s.title}" key="#{s.id}" ></si:selectItems>
  |       </h:selectOneMenu>
  |     </h:form>
  | 

in Subject.java:

  | 
  | @Name("subject")
  | public class Subject implements java.io.Serializable {
  | 	private static final long serialVersionUID = -1926918108184076192L;
  | 	private String id = "";
  | 	private String title = "";
  | 	private String description = "";
  | }
  | 
It also contains getters and setters, but for brevity I left them out.

In SubjectFactoryBean.java

  | @Stateless
  | @Name("subjectFactory")
  | @Scope(APPLICATION)
  | public class SubjectFactoryBean implements SubjectFactory {
  | 	
  |     @Logger
  |     private Log log;
  |     
  |     @Out
  |     private List<Subject> subjects;
  | 
  |     @Factory("subjects")
  |         public void load() {
  | 		log.debug("Loading subject list.");
  | 		
  | 		subjects = new ArrayList<Subject>();
  | 		subjects.add( new Subject("sub-a", "Subject A") );
  | 		subjects.add( new Subject("sub-b", "Subject B") );
  | 		subjects.add( new Subject("sub-c", "Subject C") );
  | 		
  | 		log.debug("Subject list contains #0 entries.", subjects.size() );
  | 	}
  | }
  | 

I'm getting the following error:


  | Value is no String (class=mil.fits.survey.Subject$$EnhancerByCGLIB$$5cdc06c9, value=subject = ) and component selectSubject:_id12with path: {Component-Path : [Class: javax.faces.component.UIViewRoot,ViewId: /home.xhtml][Class: javax.faces.component.html.HtmlForm,Id: selectSubject][Class: javax.faces.component.html.HtmlSelectOneMenu,Id: _id12]} does not have a Converter
  | 

So I try adding a converter....

Adding this method to SubjectFactoryBean.java

  | 	public Converter getConverter() {
  | 		return new SelectItemsConverter() {
  | 			@Override
  | 			protected Object convertToObject(FacesContext arg0, UIComponent arg1, String arg2) 
  |                             throws ConverterException {
  | 				log.debug("convertToObject(#0, #1, #2)", arg0, arg1, arg2);
  | 				// TODO Auto-generated method stub
  | 				return new Subject(arg2, arg2);
  | 			}
  | 
  | 			@Override
  | 			protected String convertToString(FacesContext arg0, UIComponent arg1, Object arg2) 
  |                             throws ConverterException {
  | 				log.debug("convertToString(#0, #1, #2)", arg0, arg1, arg2);
  | 				// TODO Auto-generated method stub
  | 				return arg2.toString();
  | 			}
  | 			
  | 		};
  | 	}
  | 

And in home.xhtml...

  |     <h:form id="selectSubject">
  |       <h:selectOneMenu value="#{subject}" converter="#{subjectFactory.converter}">
  |         <si:selectItems value="#{subjects}" var="s" label="#{s.title}" key="#{s.id}" ></si:selectItems>
  |       </h:selectOneMenu>
  |     </h:form>
  | 
  | 

Gives me the following error...

  | /home.xhtml @16,83 converter="#{subjectFactory.converter}": Exception 
  | getting value of property converter of base of type : 
  | org.jboss.seam.intercept.Proxy$$EnhancerByCGLIB$$4461012a
