我目前正在我们的自定义primefaces / jsf ui组件中集成p:confirmDialog。但是当在此层次结构中使用p:confirmDialog时,它失败了:
p:panel
p:tabView
p:tab
h:form
p:panel
h:panelGroup
h:panelGroup
p:commandButton
p:confirmDialog
在其他形式上它成功了:
h:form
p:panel
h:panelGroup
h:panelGroup
p:commandButton
p:confirmDialog
p:panel
p:tabView
p:tab
请注意,最明显的区别之一是定义了h:form,并且confirmDialog位于tabView内(失败)。
以下是我如何定义confirmDialog:
<p:commandButton id="saveButtonWithMessage"
rendered="#{cc.attrs.edit and !empty(cc.attrs.backingBean.objectId) and !empty(cc.attrs.updateConfirmationMessage)}"
value="#{messages['action.save']}" icon="ui-icon-check"
onclick="PF('saveButtonWithMessageDialog').show();">
</p:commandButton>
<p:confirmDialog message="#{cc.attrs.updateConfirmationMessage}"
widgetVar="saveButtonWithMessageDialog" showEffect="fade"
hideEffect="fade">
<p:commandButton ajax="#{cc.attrs.ajaxSubmit}"
value="#{messages['commons.yes']}" styleClass="ui-confirmdialog-yes"
icon="ui-icon-check" oncomplete="saveButtonWithMessageDialog.hide()"
action="#{cc.attrs.backingBean.saveOrUpdate(cc.attrs.killConversationOnSave)}">
<f:param name="edit" value="#{cc.attrs.edit}" />
</p:commandButton>
<p:commandButton value="#{messages['commons.no']}" type="button"
styleClass="ui-confirmdialog-no" icon="ui-icon-close"
onclick="PF('saveButtonWithMessageDialog').hide()" />
</p:confirmDialog>
在第二个例子中,浏览器成功发送了请求并获得了响应,但它仍然停留在灰色模态屏幕上。
这是我得到的部分回应:
<partial-response>
<changes>
<update id="tabView:j_idt625"><div id="tabView:j_idt625" class="ui-messages ui-widget" aria-live="polite"></div></update>
<update id="tabView:j_idt680"><div id="tabView:j_idt680" class="ui-messages ui-widget" aria-live="polite"></div></update>
<update id="tabView:j_idt732"><div id="tabView:j_idt732" class="ui-messages ui-widget" aria-live="polite"></div></update>
<update id="tabView:j_idt788"><div id="tabView:j_idt788" class="ui-messages ui-widget" aria-live="polite"></div></update>
<update id="javax.faces.ViewState">3685613370368244617:-6252032147041871407</update>
</changes>
</partial-response>
有什么想法吗?
答案 0 :(得分:0)
这就是我解决问题的方法,请注意所有按钮都是基于ajax的。要从confirmDialog导航到另一个页面,我需要创建一个触发remoteCommand的按钮,remoteCommand调用backingBean操作,该操作返回faces-config.xml中定义的字符串导航。
<!-- Update with message -->
<p:remoteCommand id="remoteUpdateWithMessageButton"
action="#{backingBean.action}"
name="updateWithMessage" oncomplete="handleUpdateWithMessageComplete(xhr,status,args)" />
<p:commandButton id="saveButtonWithMessage"
rendered="#{trueOrFalse}"
value="Save" icon="ui-icon-check"
oncomplete="PF('saveButtonWithMessageDialog').show()">
</p:commandButton>
<!-- Update the message handling when -->
<p:confirmDialog id="confirmUpdateWithMessage" appendTo="@(body)"
widgetVar="saveButtonWithMessageDialog" showEffect="fade"
hideEffect="fade" severity="alert"
message="#{(cc.attrs.updateConfirmationMessage eq '') ? messages['confirmationMessage.confirmUpdate'] : cc.attrs.updateConfirmationMessage}">
<p:commandButton id="updateOk" value="yes"
styleClass="ui-confirmdialog-yes" icon="ui-icon-check"
oncomplete="updateWithMessage()"
onclick="PF('saveButtonWithMessageDialog').hide()">
</p:commandButton>
<p:commandButton id="updateKO" value="#{messages['commons.no']}"
type="button" styleClass="ui-confirmdialog-no" icon="ui-icon-close"
onclick="PF('saveButtonWithMessageDialog').hide()" />
</p:confirmDialog>
<!-- Update with message -->
<script type="text/javascript">
//<![CDATA[
function handleUpdateWithMessageComplete(xhr, status, args) {
var result = args.result;
if(typeof(result)!="undefined" && !result){
PF('confirmCannotUpdateWithMessageDialog').show();
}
}
//]]>
</script>
