jsf 2 -单击第二个按钮后，jsf输入字段值消失

Question

问题是，我试图按下一个按钮->去支持bean ->设置布尔值为假/真，并相应地显示一个弹出窗口。如果弹出窗口显示->调用该方法并执行它。

以上是工作，但输入字段，我得到的第一个按钮点击后似乎丢失了，当我点击弹出面板中的按钮。因此，我在第一次单击(它们在backing bean对象中获得)之后获得的所有参数都随着第二次单击(在弹出窗口中)而消失。这是什么呢?

它都在一个表单中，所有的按钮和输入字段等都在一个a4j:区域。在后台没有验证错误。

我有以下支持bean(请注意，我故意没有将整个bb与所有注入等一起放在那里):

@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 ...

这是我的视图(assign.xhtml):

我很抱歉没有使视图更紧凑，但因为我猜问题是在视图中，我正在显示整个结构。

Answer 1

终于找到了

必须添加2个不同的a4j:区域。1用于表单，1用于弹出面板。
