IcCube报表横向打印问题：自定义打印参数未生效如何解决？

使用IcCube Reporting V8，通过ic3-reporting-api创建了包含横向布局的主题，基于该布局的报表在界面显示横向正常。添加两个打印按钮分别设置pageOrientation为landscape、layoutId为自定义布局ID，但调试发现打印参数未被识别：pageOrientation仍为portrait，layoutId仍为undefined。

相关代码配置 #

创建主题的布局代码 #

}, {
        layoutConfigId: 'My. A4 (Landscape) Layout',
        pageSize: {
            type: "known",
            name: "A4",
        },
        pageOrientation: "landscape",
        pageMargin: {
            sizeUnits: "cm", ...

打印按钮配置 #

action, action@appNotificationType, action@appNotificationPayload
Générer un PDF landscape,print-report,"{"paperSizeName":"A4","pageOrientation":"landscape","fileName":"Tableau de bord Salle A Landscape (@{DateSelected:asCaption}).pdf"}"
Générer un PDF layoutId,print-report,"{"paperSizeName":"A4","layoutId":"My. A4 (Landscape) Layout","fileName":"Tableau de bord Salle A Landscape (@{DateSelected:asCaption}).pdf"}"

调试打印参数信息 #

01:31:05.276 [General] print options 
Object { inBrowser: false, withState: true, appUrl: "https://localhost:44361/icCube/report/editor", appLocalUrl: "dft", appCustomizationUrl: "-", timeoutS: 300, debugWaitingTimeS: 900, layoutId: undefined, fitToPage: true, fileName: "Tableau de bord Salle A Landscape (2021 nov.).pdf", … }

问题根源在于打印按钮的CSV配置中，JSON payload的双引号未正确转义。CSV格式要求字段内的双引号必须用双引号进行转义，否则JSON解析失败，参数无法被正确读取。

修改后的打印按钮配置如下：

action, action@appNotificationType, action@appNotificationPayload
Générer un PDF landscape,print-report,"{""paperSizeName"":""A4"",""pageOrientation"":""landscape"",""fileName"":""Tableau de bord Salle A Landscape (@{DateSelected:asCaption}).pdf""}"
Générer un PDF layoutId,print-report,"{""paperSizeName"":""A4"",""layoutId"":""My. A4 (Landscape) Layout"",""fileName"":""Tableau de bord Salle A Landscape (@{DateSelected:asCaption}).pdf""}"

验证要点 #

修改后重新调试打印参数，应能看到pageOrientation变为landscape，layoutId正确填充为My. A4 (Landscape) Layout。额外可通过以下方式确认：

• 查看浏览器控制台的网络请求，确认打印接口的参数已正确传递
• 确保自定义布局ID与主题中定义的layoutConfigId完全一致，注意大小写和特殊字符
