JSF输入字段值在第二次按钮点击后消失

Question

问题是我试图按下一个按钮 - >去支持bean - >设置一个布尔值为false/true，并相应地显示一个弹出窗口。如果弹出窗口显示 - >调用方法并执行它。

上述工作正常，但当单击弹出式面板中的按钮时，第一次单击按钮后出现的输入字段似乎已丢失。所以我第一次点击后获得的所有参数（他们进入后台bean对象）都会随着第二次点击而消失（在弹出窗口中）。这可能是什么？

这一切都在一种形式，所有的按钮和inputfields等在一个a4j：地区..后台没有验证错误。

我有以下支持bean（注意，我故意没有把整个BB在那里与人的内喷射等）：

@ManagedBean(name = "dossierInTreatmentBB") 
@ViewScoped 
public class DossierInTreatmentBackingBean { 

/** The show center popup. */ 
private boolean showCenterPopup; 

/** The continue assign without report. */ 
private boolean continueAssignWithoutReport; 



public void assign() throws IOException { 

    if (!continueAssignWithoutReport) { 
     ExternalOffice eo = annucompLocal.findOfficeByCrestraCode(getEntity().getServiceTreatment()); 

     showCenterPopup = OfficeLevel.CENTER.equals(eo.getServiceType().getOfficeLevel()) 
    } 

    if (!showCenterPopup) { 
     dossierInTreatmentDossierLocal.assign(); 
     //refreshes the entity 
     setDTO(null); 

     if (!DossierContext.isEditAllowed(getDossier())) { 
      String url = getRequestContextPath() + "/dossier/consult/detail.jsf?id=%s"; 
      redirect(url, getDossier().getId().toString()); 
     } 
    } 
} 

/** 
* Assign without report. 
* @throws IOException Signals that an I/O exception has occurred. 
*/ 
public void assignWithoutReport() throws IOException { 
    showCenterPopup = false; 
    continueAssignWithoutReport = true; 
    assign(); 
} 


... needed getters and setters ... 

，这是我的看法（分配。 XHTML）：

我不使意见更紧凑抱歉，因为我猜问题是定位于视图我展示的整体结构。

Answer 1

终于找到了。不得不添加2个不同的a4j：区域。 1表示弹出面板，1表示弹出面板。
