 我发现 原来是我的struts-config.xml 里的 form-property 等标签多配了两个重复的！！！去掉就没问题了！！

form-bean name="customizationMenuForm" type="org.apache.struts.action.DynaActionForm">
			<form-property name="group" type="java.lang.String"/>
			<form-property name="userLevel" type="java.lang.String"/>
			<form-property name="serviceCategoryGroupIds" type="java.lang.String"/>
			<form-property name="serviceCategoryGroupIds" type="java.lang.String"/>
		</form-bean>
