在Flex中用XML填充组合框_Xml_Apache Flex_Combobox_Httpservice - Fatal编程技术网

在Flex中用XML填充组合框

在Flex中用XML填充组合框,xml,apache-flex,combobox,httpservice,Xml,Apache Flex,Combobox,Httpservice,我试图用XML文件中的国家填充一个组合框。不幸的是,组合框没有被填充。我应该如何解决这个问题?提前谢谢 这是我的密码: protected function navigatorcontent2_creationCompleteHandler(event:FlexEvent):void { fillCboCountries.addEventListener(ResultEvent.RESULT, fillCombobox); fillCboCountries.send();

这是我的密码:

    fillCboCountries.addEventListener(ResultEvent.RESULT, fillCombobox);    
    fillCboCountries.send();

protected function fillCombobox(event:ResultEvent):void

    cboCountries.dataProvider=event.result.global.countryItem;              
}

fillcboccountries.send();
}
受保护的函数fillCombobox(事件:ResultEvent):void
{

在看不到服务调用的XML响应的情况下,我唯一能建议的是将
HTTPService
上的设置为“e4x”:



这告诉HTTPService响应是XML,并且您希望使用e4x表达式获取数据。

您的代码没有错误。我已将其粘贴到我的空项目中,并在组合框中看到您的字段

我唯一改变的是http,而不是https

所以问题在于数据源,而不是源代码!尝试不使用https

谢谢大家的帮助


我通过将代码复制到一个新项目中解决了这个问题。不幸的是,我不知道最初的项目出了什么问题。

您能发布您的XML结构吗?到真实数据的路径可能有问题。嗨,我的XML是这样的:。。。。。。。。。。。。。1阿富汗。。。。。。。。。。。。。。2阿尔巴尼亚。。。。。。。。。。。。。。。。。。。。。。。确认<代码>https://marnixcoosemans2013.dreamhosters.com/scripts/countries_select.php不可用,但是,它是用http:打开的。谢谢,源代码对我也是可用的,但是在我的代码中有一个http请求,我得到了这个错误:RPC Fault faultString=“http request error”faultCode=“Server.error.request”faultDetail=“error:[IOErrorEvent type=“ioError”bubbles=false cancelable=false eventPhase=2 text=“Error#2032:流错误。URL:.URL:这可能是安全设置的问题。这是Flex沙盒的问题。通常,crossdomain.xml文件会有所帮助。
