Question

JSF标签h:selectmanycheckbox的问题

后台
public class info {
private String[] name;
public String[] getName(){return name;}
public void setName(String name){this.name = name;}
}
前台
<h:selectManyCheckbox id="name" value="#{info.name}" >
<f:selectItem itemValue='xiaom' itemLabel='小明'/>
<f:selectItem itemValue='xiaow' itemLabel='小王'/>
<f:selectItem itemValue='xiaoh' itemLabel='小红'/>
</h:selectManyCheckbox>
page.xml
<param name="from"/>
<param name="name" value="#{info.name}"/>

代码是上面这样的。在提交的时候报错，类型转换错误。还没到set方法就挂了……有知道的朋友吗？请指教，多些了……
javax.el.ELException: Can't set property 'name' on class 'org.domain.psw.session.info_$$_javassist_seam_4' to value '[Ljava.lang.String;@10c2da3'
139889gong：呃，源码是没错的……原来想写简单点结果弄错了，这是源码。试了许多中绑定类型，Integer[]、Long[]、String[]这几个报错都差不多，就是类名不一样，绑定List<String>时报错：javax.el.ELException: Can't set property 'systemtype' on class 'org.domain.psw.session.info_$$_javassist_seam_4' to value '[100,200,300]'，[100,200,300]就是我希望从前台获取的数组
后台
public class ScamsuspectList extends EntityQuery<Scamsuspect> {
private String[] systemtype;
public String[] getSystemtype() { return systemtype;}
public void setSystemtype(String[] systemtype) {this.systemtype = systemtype;}
}
前台
<s:decorate template="../../layout/display.xhtml">
<ui:define name="label">检测引擎</ui:define>
<h:selectManyCheckbox id="systemtype" value="#{scamsuspectList.systemtype})">
<f:selectItems value="#{queryMgt.getSystemtypeItems()}" />
</h:selectManyCheckbox>
</s:decorate>
page.xml
<param name="from"/>
<param name="systemtype" value="#{scamsuspectList.systemtype}"/>

老大你在好好看看这段代码： public void setName(String name){this.name = name;}
上面定义数组变量！在SET方法参数也要定义数组啊！
修改成这样试试：public void setName(String[] name){this.name = name;}
