我目前正在测试 PEGA 应用程序的 UI，而我偶然发现了一个问题，即我单击一个按钮，而该按钮又会保存一个项目并关闭框架。单击方法完成后，它仍在寻找 y 帧，但停留在 x 帧上，因此崩溃。

使用时会出现以下问题：

driver.findElement(By.x("selector")).click(); 

框架正在切换，并且在框架中它仍在尝试定位上一个活动框架（此时不可见）。

我在 PegaGadget2Ifr 帧上，但最终在 PegaGadget1Ifr 上进行单击。

这是我正在运行的代码：

    public void saveProjectAsDraft(){
        Project_page pp = new Project_page(FDMPortal.getActiveFrameId(true), testEnv);
        FDMObjectsBean.setProject_page(pp);
        pp.saveDraft();
    }

public Workplace_details_page saveDraft(){
        findElement(SAVE_DRAFT).click();
        return new Workplace_details_page(getActiveFrameId(true),testEnv);
    }

收到此错误消息。
