Question

问题是我正在尝试按下按钮 - ＆gt;转到支持bean - ＆gt;将布尔值设置为false / true并相应地显示弹出窗口。如果弹出窗口显示 - ＆gt;调用方法并执行它。

上面的工作正常，但是当我点击弹出式面板中的按钮时，我点击第一个按钮后输入的字段似乎丢失了。所以我在第一次点击后得到的所有参数（它们都进入了支持bean对象）都没有第二次点击（在弹出窗口中）。这可能是什么？

它只是一种形式，所有按钮和输入字段等都在一个a4j：region ..幕后没有验证错误。

我有以下支持豆（请注意，我故意没有把整个bb放在那里注射等...）：

@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 ...

这是我的观点（assign.xhtml）：

我很抱歉没有让视图更紧凑，但是因为我猜测问题位于视图中我正在显示整个结构。

终于找到了它。

必须添加2个不同的a4j：区域。表单为1，弹出面板为1 ..

单击第二个按钮后，JSF输入字段值消失
