Question

当我在Jetty服务器上运行我的JSF应用程序时，运行正常。

但是当我把它移到Weblogic服务器上时，它开始给我这个错误。

wsListing.xhtml如下：

                                <f:setPropertyActionListener
                                    target="#{wsListingBean.webServiceId}" value="abcService" />
                            </h:commandLink></td>
                    </tr>
                    <tr>
                        <td><h:commandLink value="Second Web Service"
                                action="#{wsListingBean.action}">
                                <f:setPropertyActionListener
                                    target="#{wsListingBean.webServiceId}" value="filterabc" />
                            </h:commandLink></td>
                    </tr>
                    <tr>
                        <td>Third Web Service</td>
                    </tr>
                    <tr>
                        <td>Fourth Web Service</td>
                    </tr>
                    <tr>
                        <td>Fifth Web Service</td>
                    </tr>
                </table>
            </h:form>
        </div>
        <ui:include src="footer.xhtml" />
    </h:body>
</f:view>
</html>

当我点击任何命令链接时，问题就出现了：

<h:commandLink value="First Web Service"
                                    action="#{wsListingBean.action}">
                                    <f:setPropertyActionListener
                                        target="#{wsListingBean.webServiceId}" value="abcService" />

任何人都知道这种观点状态是什么？

Answer 1

您是否将web.xml中的PROJECT_STAGE设置为开发？如果是这样，您可以将其切换到生产并查看问题是否消失？我在WebLogic上有一个类似的（如果不是相同的）错误消息，并认为该更改修复了它。

Answer 2

我已在 web.xml 中添加以下行来修复错误

    <context-param>
    <!--description>
        The location where state information is saved. Valid values
        are 'server' (typically saved in HttpSession) and 'client'
        (typically saved as a hidden field in the form. Default is
        server.
        </description-->
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>server</param-value>
</context-param>
<context-param>
    <!--description>
        Number of Views to be stored in the session when Server-Side
        State Saving is being used. Default is 20.
        </description-->
    <param-name>
        org.apache.myfaces.NUMBER_OF_VIEWS_IN_SESSION
    </param-name>
    <param-value>20</param-value>
</context-param>

找不到视图标识符的已保存视图状态
