Struts2 jquery jqgrid网格编辑时的动态下拉列表

这是我的jsp代码

<s:url id="myEditOptions" action="myEditOptions.action"/>
<sjg:gridColumn name="branch" align="left" index="Branch" id="bnch" title="Branch" 
    editable="true" onclick="" edittype="select" editoptions="%{myEditOptions}"  />

struts.xml代码

这里是Actionclass代码

未显示分支下拉列表。如果有人知道，请帮助我在使用struts2 jquery jqgrid编辑网格时获取动态下拉列表。甚至我也可以通过使用普通struts2选择选项获得动态下拉列表

<s:select label="What's your favor search engine" 
    headerKey="-1" headerValue="Select Search Engines"
    list="searchEngine" 
    name="yourSearchEngine" />

像这样，在执行struts2网格编辑选择选项时，我需要相同的功能Dynamic dropdownlist！是的，在使用struts2 jquery jqgrid编辑网格时，终于找到了设置动态下拉列表的解决方案，并使下面的更改现在可以正常工作了

public String getDynamicBranch(){       
    customerList = exampleDao.getCustomerListData();
    myEditOptions = "<select>";
    for(Customer cust:customerList){
        if(cust.getBranch() != null && cust.getBranch().length() !=0) {
            System.out.println("******Branch values***:::"+cust.getBranch());
            myEditOptions += "<option value="+cust.getBranch()+">"+cust.getBranch();
        }

    }
    myEditOptions += "<select>";
    //Collections.sort(branchList);     
    return "success";
}

<s:select label="What's your favor search engine" 
    headerKey="-1" headerValue="Select Search Engines"
    list="searchEngine" 
    name="yourSearchEngine" />

public String getDynamicBranch(){       
    customerList = exampleDao.getCustomerListData();
    myEditOptions = "<select>";
    for(Customer cust:customerList){
        if(cust.getBranch() != null && cust.getBranch().length() !=0) {
            System.out.println("******Branch values***:::"+cust.getBranch());
            myEditOptions += "<option value="+cust.getBranch()+">"+cust.getBranch();
        }

    }
    myEditOptions += "<select>";
    //Collections.sort(branchList);     
    return "success";
}
