我有一个带有 Seam 生成的 Entity 和 EntityHome 类型支持 bean 的输入表单。由于用户在保存输入的数据之前需要一个确认弹出对话框,因此我将自动生成的 'h:commandButton' 替换为 'a4j:commandButton' 并将一个模式面板附加到它的 'oncomplete' 事件中:

Edit.xhtml 输入表单位:

. . . . . 

<div class="actionButtons">

        <a:commandButton id="save"
                      value="Save"
                 oncomplete="#{rich:component('confirmCreatePanel')}.show();"
                   disabled="#{!userProjectRolesHome.wired}"
                   rendered="#{!userProjectRolesHome.managed}">
            <s:conversationId/>
        </a:commandButton>

    </div>

    <rich:popupPanel modal="true" id="confirmCreatePanel" moveable="false" resizeable="false" height="120">
      <f:facet name="header">Confirm</f:facet> 
      <div class="actionButtons">
        <rich:panel style="align:center;">
          <h:outputText value="Are you sure you want to create this ?" />
          <table width="100%">
            <tbody>
              <tr>
                <td align="center" width="50%">
                  <a:commandButton type="submit" value="Yes" action="#{userProjectRolesHome.persist}"
                    oncomplete="#{rich:component('confirmCreatePanel')}.hide()"/>
                </td>
                <td align="center" width="50%">
                  <a:commandButton type="submit" value="No" onclick="#{rich:component('confirmCreatePanel')}.hide()"/>
                </td>
              </tr>
            </tbody>
          </table>
        </rich:panel>
      </div> 
    </rich:popupPanel>

当单击“保存”按钮时,“confirmCreatePanel”会弹出 OK,但是当用户单击 mod.panel 时“是”并调用“persist()”时,我会收到一个异常,抱怨成员变量为“无效的'。

如果我从“a4j:commandButton”或“h:commandButton”的“action”属性中调用“persist()”,一切正常。“未完成”处理把事情搞砸了,它曾经工作过。

相同的代码适用于 Seam 2.2.0.Final/RF3.3.3/JSF1.2。升级到 Seam2.3.0.Final/RF4/JSF2 后它现在不工作了这里有什么变化?

将 's:conversationId' 添加到模型面板的 'Yes' 'a:commandButton' 似乎现在已经修复了它。
