PropertyTypeDescriptor和Spring 3.1.2

我正在使用Spring-Flex 1.5.2和Spring 3.1.2开发一个项目，并且最近在向我的项目中添加了一些DAO之后，我试图填充WebLogic控制台时开始出现此错误我的一个组合：PropertyTypeDescriptor和Spring 3.1.2

谷歌已经失败了我在这一个...所以任何帮助，非常感谢。

我有我的注释与@RemotingDestination服务，并创造了我的MXML远程对象，像这样：

<s:RemoteObject id="marketSegment" destination="marketSegmentServiceImpl" endpoint="http://localhost:7001/scpi/messageBroker/amf"></s:RemoteObject>

然后我在我的组合框添加此：

dataProvider="{marketSegment.findAllCatalogs.lastResult}"

这在我的创作完成：

private function init():void{ 
    marketSegment.findAllCatalogs(); 
    biotech.findAllCatalogs(); 
}

这是工作取obects只有原始类型属性，但在尝试获取具有复杂类型属性的任何对象时会出现提及的错误。

你什么时候遇到这个错误？你用什么代码来试图“填充我的一个组合”？ – JeffryHouser

我添加了代码即时通讯使用在灵活的一面，也是我注意到简单与复杂类型属性。谢谢！ – jhurtado

我假设这是一个Java错误;在这种情况下，我不确定Flex代码如何提供帮助。 – JeffryHouser

看起来有些版本不兼容。在Spring 3.1中删除了类org.springframework.core.convert.support.PropertyTypeDescriptor！

看看包含org.springframework.flex.core.io.HibernateProxyConverter的罐子。也许你会在pom.xml中找到需要的spring-core版本。
