Question

我具有Main.MXML文件，在该文件下有另一个视图ReportTab.mxml（画布是此页面的根标记）在此页面中我还有另一个页面RaviReport.mxml（画布是此页面的根标记）提交它们后，我有了formItem，我需要使用RemoteObject标记从Backed获取数据，并且必须在DATAGRID中呈现数据。加载Main.mxml文件时，我可以成功编译，但是在控制台中出现错误。 EventDispatcher.js：74未捕获的TypeError：indicatorClass不是构造函数在mx.containers.FormItem.mx_containers_FormItem_displayIndicator（FormItem.js：718）在mx.containers.FormItem.updateDisplayList（FormItem.js：397）在mx.containers.FormItem.updateFormItemDisplayList（FormItem.js：409）在mx.containers.FormItem.FormItemLayout.updateDisplayList（FormItem.js：1101）在mx.containers.FormItem.FormItemLayout.mx.containers.beads.BoxLayout.layout（BoxLayout.js：115）在mx.containers.FormItem.FormItemLayout.org.apache.royale.core.LayoutBase.performLayout（LayoutBase.js：247）在mx.containers.FormItem.FormItemLayout.org.apache.royale.core.LayoutBase.handleLayoutNeeded（LayoutBase.js：152）在mx.containers.FormItem.goog.events.EventTarget.fireListeners（eventtarget.js：284）在Function.goog.events.EventTarget.dispatchEventInternal_（eventtarget.js：381）在mx.containers.FormItem.goog.events.EventTarget.dispatchEvent（eventtarget.js：196

我尝试删除FormItem，并且刚刚在RaviReport.mxml中添加了，但是我的画布隐藏了label元素。请建议我如何使用Royale中的navigationBar或ViewSTACK集成视图。

Answer 1

如果从一个简单的工作文件开始并向其中添加内容，我的建议。

在Royale中，没有像Flex（MX / Spark）中那样只有一个UI集。您可以选择基本，珠宝，仿真（MX / Spark），MDL。因此，第一件事是：您要选择哪种UI集？考虑到仿真（MX / Spark）仍在进行中，无法完全正常工作。也许Jewel或Basic会更容易实现，但是您需要使UI代码适应此新标签和API。

例如，在Jewel中，您可以检查Tour de Jewel和source code以查看其操作方式

如何从Flex UI转换为Apache Roayle
