Java 从列表框ZK中的多个选择中获取值

Java 从列表框ZK中的多个选择中获取值,java,web-applications,zk,Java,Web Applications,Zk,我想问一下如何从列表框中的多重选择中获取值,我在zul中有如下代码: <n:tr> <n:td> <label value="Privilege"/> </n:td> <n:td> <label value=""/> &

我想问一下如何从列表框中的多重选择中获取值,我在zul中有如下代码:

<n:tr>
                <n:td>
                    <label value="Privilege"/>
                </n:td>
                <n:td>
                    <label value=""/>
                </n:td>
                <n:td>

                                <listitem self="@{each=lstPrivilege}" >
                                    <listcell label="@{lstPrivilege.description}"/>
                                </listitem>
                     </listbox>

            </n:tr>

    }
 SelectedItemConverter select=new SelectedItemConverter();

       for (Activity li : (Set<Activity>)select.coerceToBean(selectedUserAcc, getListGent()))
                        {
                            al.add(li);
                        }


                        List<Activity> act=al;

希望有人能帮助我..谢谢..:D

好的,经过谷歌搜索和尝试(:D),我得到了这个问题的答案,你必须做的事情是调用你控制器中的转换器,我从ZK论坛得到的转换器 ,并更改返回对象(bot return null),我的程序如下:

<n:tr>
                <n:td>
                    <label value="Privilege"/>
                </n:td>
                <n:td>
                    <label value=""/>
                </n:td>
                <n:td>
                     <listbox id="designations" model="@{addUser$composer.lstPrivilege}" selectedItem="@{selectedUserAcc, converter=com.nsia.doku.escrow.converter.SelectedItemConverter}" multiple="true" checkmark="true" width="200px">
                                <listitem self="@{each=lstPrivilege}" >
                                    <listcell label="@{lstPrivilege.description}"/>
                                </listitem>
                     </listbox>
                </n:td>
            </n:tr>
            <n:tr>
                <n:td>

                </n:td>
                <n:td>

                </n:td>
                <n:td>
                     <button label="Submit" onClick='
                     import com.dokuescrow.dto.Activity;
                     ArrayList al = new ArrayList();
                        for (Activity li : selectedUserAcc)
                        {
                            al.add(li.activityId);
                        }
                        alert(al);
                     '/>
                </n:td>
            </n:tr>
public void onClick$submit(Event event){
        try {

            ArrayList al = new ArrayList();
                        for (Activity li : selectedUserAcc)
                        {
                            al.add(li.getActivityId());
                        }
           alert(al.toString());
        } catch (Exception e) {
            e.printStackTrace();
        }

    }
 SelectedItemConverter select=new SelectedItemConverter();

       for (Activity li : (Set<Activity>)select.coerceToBean(selectedUserAcc, getListGent()))
                        {
                            al.add(li);
                        }


                        List<Activity> act=al;
SelectedItemConverter select=newselecteditemconverter();
对于(活动li:(Set)select.impressedobean(selectedUserAcc,getListAgent())
{
加上(李);
}
列表act=al;
所以我得到了我想要的选择对象谢谢你的关注
