[英]How get value of tag <p:menu> in primefaces
I am doing a web aplication where I have a menu with a list entities and this entities will be evaluated all it is in a facelets template and I now I need to get the ID of this entity to can evaluate How it do ? 我正在做一个网络应用程序,其中有一个带有列表实体的菜单,该实体将在facelets模板中进行评估,而现在我需要获取该实体的ID才能评估其工作方式?
I thought it: 我以为:
<p:menu model="#{entidadView.menuModel}" toggleable="true" >
<p:ajax listener="#{grupoView.storeEntidad}"/>
</p:menu>
and My bean it is: 而我的豆子是:
public MenuModel getMenuModel(){
DefaultSubMenu subMenu2 = new DefaultSubMenu("Auditoria");
for (Entidad entidad : getAllEntidad() ){
item = new DefaultMenuItem(entidad.getNombre());
item.setOutcome("/auditar.xhtml");
subMenu2.addElement(item);
}
model.addElement(subMenu2);
//Event to Ajax
public void storeEntidad(ValueChangeEvent evento){
this.idEntidad = evento.getNewValue().toString();;
System.out.println(idEntidad);
}
but say me this error: 但是说我这个错误:
<p:ajax> Unable to attach behavior to non-ClientBehaviorHolder parent
I did it only send the parameter by the URL of my web pages and I capture it then. 我这样做只是通过网页的URL发送参数,然后捕获了它。 My bean:
我的豆子:
public MenuModel getMenuModel(){
DefaultSubMenu subMenu2 = new DefaultSubMenu("Auditoria");
for (Entidad entidad : getAllEntidad() ){
idEntidad = String.valueOf(entidad.getEntidad_id());
item = new DefaultMenuItem(entidad.getNombre());
item.setParam("entidad", idEntidad);
item.setOutcome("/auditar.xhtml");
subMenu2.addElement(item);
}
model.addElement(subMenu2);
}
And the next Pages I capture so: 我捕获的下一页是:
<html ...>
<f:metadata>
<f:viewParam name="entidad" value="#{grupoView.idEntidad}"/>
</f:metadata>
<body>
And finaally It was okay !!! 最后,还可以! (Y)
