-------------------------------------------------------------------------------------------

                 Key: TRINIDAD-1518
                 URL: https://issues.apache.org/jira/browse/TRINIDAD-1518
             Project: MyFaces Trinidad
          Issue Type: Bug
    Affects Versions:  1.2.11-core
         Environment: java 6u13
tomcat 6.0.16

            Reporter: Matthias Heinrich


On rendering an <tr:selectOneChoice> Listing 1 i got this warning:
#25.06.2009 11:14:39 org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.SimpleSelectOneRenderer _getSelectedIndex
#WARNUNG: Es konnte kein ausgewähltes Element gefunden werden, das mit dem Wert "2" in CoreSelectOneChoice[UIXEditableFacesBeanImpl, id=j_id25] übereinstimmt

So if the site is rendered the selection isn't  correct .

Listing 1 the .jspx file
<pre>
    <tr:selectOneChoice autoSubmit="true" converter="#{locationConverterBean}"
                                       label="#{labels.location}" required="true"
                                       unselectedLabel=" " value="#{singleItemBean.inventoryItem.location}"
                                       valueChangeListener="#{singleItemBean.processLocationChanged}">
        <f:selectItems value="#{locationBean.locationItems}" />
    </tr:selectOneChoice>
</pre>

Listing 2 the converter Bean:

public class LocationConverter implements Converter
{
       
        @Autowired
        LocationService locationService;
       
        public LocationConverter(){ }
       
        public LocationConverter(LocationService locationService)
        {
                this.locationService = locationService;
        }

        @Override
        public Object getAsObject(FacesContext context, UIComponent component, String value) throws ConverterException
        {
                if(value == null)
                        return null;
                else if(value.isEmpty() || value.equals("-1"))
                        return null;
                else
                {
                        try
                        {
                                return locationService.getLocationById(Long.parseLong(value));
                        }
                        catch (ServiceLayerException e)
                        {
                                // TODO: handle exception
                                throw new ConverterException(new FacesMessage(e.getLocalizedMessage()));
                        }
                }
        }

        @Override
        public String getAsString(FacesContext context, UIComponent component, Object value) throws ConverterException
        {
                if(value == null)
                        return null;
                else if(value instanceof Location)
                        return Long.toString(((Location)value).getId());
                else if(value instanceof String)
                        return (String)value;
                else if(value instanceof Long)
                        return ((Long)value).toString();
                else if(value instanceof Integer)
                        return ((Integer)value).toString();
                else
                {
                        throw new ConverterException(new FacesMessage("LocationConverter: wrong Type"));
                }
        }
}

It seems that the Converrter isn't called an the rendering phase.
It also seems like the issue reported from Fred Davis see here http://www.mail-archive.com/users@.../msg52354.html.
