[jboss-user] [JBoss Seam] - selectOneMenu with s:convertEntity and noSelectionLabel does

[hurzeler]

Hello there,

I got a simple menu using


  | <ice:selectOneMenu id="#{messages['region']}"							styleClass="selectTagMenu" value="#{siteList.selectedRegion}"
  | 	partialSubmit="true">
  | <s:selectItems value="#{regions.resultList}" var="region"
  | 	label="#{region.name}" noSelectionLabel="Select..."/>
  | <s:convertEntity />
  | </ice:selectOneMenu>
  | <ice:commandButton value="#{messages['reset']}"
  | 	action="#{siteList.reset}" /
  | 

This is all wonderful and the list is displayed. However if I don't select anything (as it is optional) and click the command button the value of the selectOneMenu is "Select..." and the EntityConverter gets confused in


  |    public Object getAsObject(FacesContext facesContext, UIComponent cmp, String value) throws ConverterException
  |    {
  |       if (value == null)
  |       {
  |          return null;
  |       }
  |       Integer key = new Integer(value);
  |       Class clazz = EntityConverterStore.instance().getClass(key);
  |       Object id = EntityConverterStore.instance().getId(key);
  |       return loadEntityFromPersistenceContext(clazz, id);
  |    }
  | 

the value is a string and not null. Hence new Integer(value) fails.

Am I missing something or is there an easy fix short from not using entities directly or leaving out the noSelectionLabel?

Your help is appreciated.
