PrimeFaces: which ajax event do I need?
提问by Daniel Szalay
I have this commandButton:
我有这个commandButton：
<p:commandButton value="View/Edit" onclick="bar.show()"
oncomplete="bar.hide(); dataSetUserDialog.show();"
actionListener="#{dataStoreBean.initUserLists}">
<p:ajax event="?" update="userSelect" ></p:ajax>
<f:param name="checkSum" value="#{dataSet.checkSum}" />
</p:commandButton>
And this dialogwith a selectManyMenuinside:
而这dialog与selectManyMenu内：
<p:dialog header="View or Edit #{dataStoreBean.currentDataSetName} users"
widgetVar="dataSetUserDialog" modal="true" width="500" height="200">
<h:form>
<p:selectManyMenu id="userSelect" value="#{dataStoreBean.selectedUsers}" style="width: 475px;">
<f:selectItems value="#{dataStoreBean.users}"
var="user" itemValue="#{user.email}"
itemLabel="#{user.email} | #{user.groupName}" />
</p:selectManyMenu>
<p:commandButton value="Done"
actionListener="#{dataStoreBean.updateDataSetsUsers}"
onclick="dataSetUserDialog.hide()" type="submit" />
</h:form>
</p:dialog>
What I want to achieve is to have updated info in the dialog I want to show. userSelectis inside that dialog. So first I want #{dataStoreBean.initUserLists}to execute, and after that update (rerender) userSelect, and then show dataSetUserDialog. How can I do this?
我想要实现的是在我想显示的对话框中更新信息。userSelect在那个对话框里面。所以首先我想#{dataStoreBean.initUserLists}执行，然后更新（重新渲染）userSelect，然后显示dataSetUserDialog. 我怎样才能做到这一点？

As BalusC suggested, I should use actioninstead of actionListener:
正如 BalusC 建议的那样，我应该使用action而不是actionListener：
<p:commandButton value="View/Edit users" onclick="loadNotification.show()"
oncomplete="loadNotification.hide(); dataSetUserDialog.show();"
action="#{dataStoreBean.initUserLists}" update="userSelect">
<f:param name="checkSum" value="#{dataSet.checkSum}" />
<f:param name="fullFileName" value="#{dataSet.fileName}.#{dataSet.fileType}" />
</p:commandButton>
<p:dialog id="userSelect" draggable="false" resizable="false"
header="View or Edit #{dataStoreBean.currentDataSetName} users"
widgetVar="dataSetUserDialog" modal="true" width="500" height="200">
<h:form>
<p:selectManyMenu value="#{dataStoreBean.selectedUsers}">
<f:selectItems value="#{dataStoreBean.users}" var="user"
itemValue="#{user.email}"
itemLabel="#{user.email} | #{user.groupName}" />
</p:selectManyMenu>
<p:commandButton value="Done"
actionListener="#{dataStoreBean.updateDataSetsUsers}"
update="dataSetMessages"
onclick="dataSetUserDialog.hide()" type="submit" />
</h:form>
</p:dialog>
