attachmentDialog2上传下载权限设置报错。

anwar312

平台是从2.7升级到3.1的，是studio5.2开发环境

页面中Grid的某列type设置为attachmentEditor2 并在页面添加了 attachmentDialog2 组件（attachmentDialog23），设置该列的attachmentDialog23属性为 attachmentDialog23 。

我想用以下代码动态控制该附件列的权限。
关键代码如下：
justep.xbl("attachmentDialog23").getAttachmentEditor().setPermission(7);

运行后页面报以下错误：
Cannot read property 'getAttachmentEditor' of null
TypeError: Cannot read property 'getAttachmentEditor' of null

请问怎么解决？

debugger调试看看justep.xbl("attachmentDialog23")正确吗？

页面justep.xbl("attachmentDialog23")正确，debugger后值为null

组件就没有获取到，确认附件组件设置的正确？

我已确认组件设置没问题，再添加一个相同组件也无法获取而且附件组件 var attachment=justep.xbl("attachmentEditor21"); 也无法获取  attachment=null

把.w和js文件发一下看看

js文件中第250行和265用到了

把附件组件跟grid布局放到一块看看
