zk上传时报的错(Event processing thread is disabled)

严重: >>org.zkoss.zk.ui.SuspendNotAllowedException: Event processing thread is disabled
>> at org.zkoss.zul.Window.doModal(Window.java:539)
>> at org.zkoss.zul.Fileupload.get(Fileupload.java:335)
>> at org.zkoss.zul.Fileupload.get(Fileupload.java:300)
>> at org.zkoss.zul.Fileupload.get(Fileupload.java:233)
>> at org.zkoss.zul.Fileupload.get(Fileupload.java:187)

需要在zk.xml中加上这些来处理事件处理线程被禁用
<system-config>
     <ui-factory-class>org.zkoss.spring.bean.ZkSpringUiFactory</ui-factory-class>
</system-config>
刚学习，希望对大家有帮助。也希望能交一些朋友
