我想从中获取价值。我尝试了这段代码,但它不起作用:
<h:form>
<h:outputLabel value="départements : "/>
<h:selectOneMenu value="#{departementController.selected.id}" onchange="submit()" immediate="true">
<f:valueChangeListener type="Controller.Listener.DepartementValueListener"/>
<f:selectItems value="#{departementController.itemsAvailableSelectOne}"/>
</h:selectOneMenu>
<h:outputLabel value="nouvelle valeur : "/>
<h:inputText value="#{departementController.comboBox}" id="dep"/>
</h:form>
控制器:
//departement change listener
private String comboBox;
public String getComboBox() {
return comboBox;
}
public void setComboBox(String comboBox) {
this.comboBox = comboBox;
}
public void departementChangeListener(ValueChangeEvent e) {
// Skip validation of non-immediate components and invocation of the submit() method.
FacesContext.getCurrentInstance().renderResponse();
this.comboBox = e.getNewValue().toString();}
sourceId=j_idt7:j_idt9[severity=(ERROR 2), summary=(j_idt7:j_idt9 : erreur de validation. La valeur est wronge.), detail=(j_idt7:j_idt9 : erreur de validation. La valeur est wronge.)]
