ICEFaces 1.8在不同portlet中的渲染（liferay）

Question

I have two Portlets: the first contains: datatable A and the second: datatable B . The two portlets are shown in the same page. I want to refresh the datatable A after I click on a command button in the datatable B .

The method called by the command button contains this code:

OnDemandRenderer onDemandRenderer = getRenderManager().getOnDemandRenderer("RENDER_GROUP");
onDemandRenderer.requestRender();

But it doesn't work. Can anyone help me please? Some hints? Thanks in advance for any help!!

I resolved the problem using static variables. Datatable A uses the dataModel object that is filled in this way in the managed bean:

dataModel=new ListDataModel(globalDD.getDetailsList());

where globalDD in the managed bean:

private GlobalDocumentDetails globalDD;
public GlobalDocumentDetails getGlobalDD() {
  return SessionBeanUtility.getGlobalDD();
}
public void setGlobalDD(GlobalDocumentDetails globalDD) {
  this.globalDD = globalDD;
}

And SessionBeanUtility.getGlobalDD() is

public static GlobalDocumentDetails getGlobalDD(){
    if (FacesUtil.getPortletSession().getAttribute(GLOBAL_DD_BEAN_KA, PortletSession.APPLICATION_SCOPE) == null)
    {
        new GlobalDocumentDetails();
        FacesUtil.getPortletSession().setAttribute(GLOBAL_DD_BEAN_KA, new GlobalDocumentDetails(), PortletSession.APPLICATION_SCOPE);
    }
    return (GlobalDocumentDetails)FacesUtil.getPortletSession().getAttribute(GLOBAL_DD_BEAN_KA, PortletSession.APPLICATION_SCOPE);
}

The datatable B contains the items of a shopping cart and the cart is a static object. I use the code that i wrote in the question in the actionListeners methods of the two datatables to refresh both.
