java方法不执行！

1 怎么检查错误？

好像没什么错误！

2.执行命令的控件不再form中，所以，网页没有提交数据过来，更不会执行命令控件的动作了！

觉得是这个...
试试看在<h:panelGrid>里面包一层<h:form>？
随便说说的

找到问题了，是B列，因为他是checkbox

 <h:commandLink id="obj__letter" styleClass="Link" title="click sort"
  value="B列"  actionListener="#{TestBean.sortColumn}">
      </h:commandLink>
    </f:facet>
     <h:outputText value="#{store2.letter}"/>
     <h:selectBooleanCheckbox id="td1" styleClass="" value="#{store2.id}" onclick="choose(this,'#{store2.id}')" ></h:selectBooleanCheckbox>  
     
  </h:column>

具体原因待查

bean里少东西
需要指定排列方式
