我试图通过编程方式在中心区域内容窗格中添加一个带有中心和右侧区域的边框容器，但是中心和右侧区域重叠--内容窗格似乎无法识别为区域。
添加边框容器和内容窗格的javascript模块：

define(["dojo/dom-construct", "dijit/registry", "dijit/layout/BorderContainer",       "dijit/layout/ContentPane", "dojo/domReady!"],
   function (domConstruct, registry, BorderContainer, ContentPane
     ) {
    return {
        Test: function () {

           ...

            //border container
            var mainContainer = new BorderContainer({
                id: 'mainContainer',
                design: 'headline',
                style: "height: 500px; width: 800px;"
            });
            //center content pane -- > gets overwritten by the right content pane
            var cp1 = new ContentPane({
                id: 'centerContainer',
                region: "center",
                content: "I'm in the center"
            });
            //right content pane
            var cp2 = new ContentPane({
                id: 'rContainer',
                region: "right",
                content: " I'm on the right",
                style: "width: 100px"
            });
            mainContainer.addChild(cp1);
            mainContainer.addChild(cp2);
            mainContainer.placeAt('Content');
            mainContainer.startup();
        }
    }
});

这是添加边框容器和其他内容窗格的中心内容窗格：

<div data-dojo-type="dijit/layout/BorderContainer" id="Main" style="width: 100%; height: 100%">
 <div data-dojo-type="dojox/layout/ContentPane" id="TOC" data-dojo-props="splitter: true, region:'leading'">
 </div>
 <div data-dojo-type="dojox/layout/ContentPane" id="Content" data-dojo-props="splitter: true, region:'center'">
 </div>
