здесь соответствующая часть страницы JSF

<h:outputText id= "diagnosisType" value="Diagnosis Type" /> 
          <p:selectOneMenu value="#{patient.diagnosisType}"> 
           <f:selectItem itemLabel="" itemValue="" /> 
           <f:selectItem value ="#{patient.diagnosisType_p}" /> 
           </p:selectOneMenu> 

и управляемый компонент

String diagnosisType; 

private Map<String,String> diagnosisType_p = new HashMap<String, String>(); 

public Patient() { 
    diagnosisType_p.put("Provisional Diagnosis", "Provisional Diagnosis"); 
    diagnosisType_p.put("Final Diagnosis", "Final Diagnosis"); 
} 

public Map<String, String> getDiagnosisType_p() { 
    return diagnosisType_p; 
} 

public void setDiagnosisType_p(Map<String, String> diagnosisType_p) { 
    this.diagnosisType_p = diagnosisType_p; 
} 

Я использую primefaces 3.5 на netbeans7.3.1

Любая помощь будет оценена.

Answer 1

использование F: selectItems

<h:outputText id= "diagnosisType" value="Diagnosis Type" /> 
<p:selectOneMenu value="#{patient.diagnosisType}"> 
    <f:selectItem itemLabel="" itemValue="" /> 
    <f:selectItems value ="#{patient.diagnosisType_p}" /> 
</p:selectOneMenu>
