primefaces: confirm dialog button not calling managedbean method
提问by mathaker
I am working in primefaces 3.3 and jsf 2.0. I have problem in deleting record in lazy datamodel. As sorting and filtering is not working properly in datatable I had to use lazydatamodel concept.Now save(through wizard), edit,sorting and filtering are working fine. When I tried to delete record from datatable, dialog is appearing and when I click on yes(command button) to delete record, instead of calling bean method control goes to load method of lazy data model. deleterecord of clientUitility.java(managedbean) not calling. can anyone give me guidance to delete record from datatable by passing client object Here is code snippet
我正在使用 primefaces 3.3 和 jsf 2.0。我在删除惰性数据模型中的记录时遇到问题。由于排序和过滤在数据表中无法正常工作，我不得不使用lazydatamodel 概念。现在保存（通过向导）、编辑、排序和过滤工作正常。当我尝试从数据表中删除记录时，会出现对话框，当我单击是（命令按钮）删除记录时，而不是调用 bean 方法控件转到惰性数据模型的加载方法。未调用 clientUtility.java(managedbean) 的 deleterecord。任何人都可以通过传递客户端对象来指导我从数据表中删除记录这是代码片段

I have changed PF 3.2 instead of PF 3.3 and it's work smoothly. Check this link: http://forum.primefaces.org/viewtopic.php?f=3&t=22216. Its bug in PF3.3. No need to change any thing in my project.
我已经更改了 PF 3.2 而不是 PF 3.3 并且它工作顺利。检查此链接：http: //forum.primefaces.org/viewtopic.php?f=3&t=22216。它在 PF3.3 中的错误。无需更改我的项目中的任何内容。

This is expected behaviour, since you are using appendToBody="true". You should add a form inside your confirm dialog.
这是预期的行为，因为您使用的是 appendToBody="true"。您应该在确认对话框中添加一个表单。
<p:confirmDialog message="Delete client?" severity="alert" widgetVar="confirmDeleteClient" visible="false" appendToBody="true" >
<h:form>
<p:commandButton value="Yes" update="clientList" immediate="true" oncomplete="confirmDeleteClient.hide()" actionListener="#{clientUitility.deleteRecord}" >
<f:setPropertyActionListener target="#{client}" value="#{client}"
</p:commandButton>
<p:commandButton value="No" onclick="confirmDeleteClient.hide()" type="button" />
</h:form>
</p:confirmDialog>

remove atributte type="button"
删除属性类型=“按钮”
回答by ARny
You can also use remoteCommand component defined outside of confirmDialog, which will be still inside form (when you use appendToBody=true).
您还可以使用在confirmDialog 之外定义的remoteCommand 组件，该组件仍将在表单内（当您使用appendToBody=true 时）。
