p:dialog 没有为 Entity 设置属性
p:dialog does not set properties to Entity
我有以下 p:datatable，其中包含两个调用“查看”和“添加”对话框的按钮。
问题在于“添加”对话框，它似乎没有为任何实体对象设置属性。
当我在 ChildrenController.java 内的 save() 方法上打断时，所有值都是 'null'。
我在用：

通过将 p:commandButton 放在对话框的 p:panelGrid 中解决了这个问题，这对我来说毫无意义！不管怎样，对话框是这样的：
<h:form id="formName">
<p:dialog>
<p:panelGrid>
<p:commandButton process="@this :formName" ajax="false" actionListener="#{bean.method()}"/>
</p:panelGrid>
</p:dialog>
</h:form>
编辑：编辑代码以提高可读性
您没有 process 您问题代码中的组件。您在那里为解决您自己的答案中的问题所做的工作是将您的 form 包含在要处理的 UIComponent 列表中。这意味着 JSF 不会查看 form 中的所有输入组件，这就是为什么它不会检索您在这些字段中输入的任何值以将它们设置到支持 bean 中的原因。
为了更好地理解进程的含义，您可以查看 at this question。
我有以下 p:datatable，其中包含两个调用“查看”和“添加”对话框的按钮。 问题在于“添加”对话框，它似乎没有为任何实体对象设置属性。

通过将 p:commandButton 放在对话框的 p:panelGrid 中解决了这个问题，这对我来说毫无意义！不管怎样，对话框是这样的：
<h:form id="formName">
<p:dialog>
<p:panelGrid>
<p:commandButton process="@this :formName" ajax="false" actionListener="#{bean.method()}"/>
</p:panelGrid>
</p:dialog>
</h:form>

您没有 process 您问题代码中的组件。您在那里为解决您自己的答案中的问题所做的工作是将您的 form 包含在要处理的 UIComponent 列表中。这意味着 JSF 不会查看 form 中的所有输入组件，这就是为什么它不会检索您在这些字段中输入的任何值以将它们设置到支持 bean 中的原因。
为了更好地理解进程的含义，您可以查看 at this question。
