Can not enable SandBox on mi Webcenter application

Question

Greetings
i have developed a webcenter application ...and i have tried to enable sandbox in order to show a save button on my composer panel in edit mode...and a pop-up message to save changes if i close before clicking the save button.
In the adf-config.xml file, i add the following lines:
<pe:page-editor-config>
<pe:security-config>
<pe:security-policies>
<pe:security-policy name="customPagePolicy" override="pagePolicy">
<pe:policy-class>oracle.webcenter.security.policy.WCPageSecurityPolicy</pe:policy-class>
</pe:security-policy>
<pe:security-policy name="customTFPolicy" override="taskFlowPolicy">
<pe:policy-class>oracle.webcenter.security.policy.WCTaskflowSecurityPolicy</pe:policy-class>
</pe:security-policy>
</pe:security-policies>
</pe:security-config>
<pe:sandbox-namespaces>
<pe:namespace path="/pages"/>
<pe:namespace path="/pageDefs"/>
</pe:sandbox-namespaces>
<session-options-factory>view.AppsSessionOptionsFactoryImpl</session-options-factory>
</pe:page-editor-config>
In the web.xml file, i add the following lines:
<filter>
<filter-name>WebCenterComposerFilter</filter-name>
<filter-class>oracle.adf.view.page.editor.webapp.WebCenterComposerFilter</filter-class>
</filter>
<filter>
<filter-name>adfBindings</filter-name>
<filter-class>oracle.adf.model.servlet.ADFBindingFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>WebCenterComposerFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>WebCenterComposerFilter</filter-name>
<url-pattern>/faces/*</url-pattern>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>
<filter-mapping>
the thing is that i am getting this errors on my weblogic server and when i choose CLOSE in the composer of the page...it does not ask if i want to save changes

I think below steps are required too.
Open the adf-config.xml file located in the ADF META-INF folder under Descriptors in the Application Resources panel.
Under the <metadata-namespaces> element, ensure that <namespace> elements are defined for all metadata for which you want to enable sandbox creation, as shown in Example 22-1.
Example 22-1 Namespace Definitions in the adf-config.xml File
<!-- Your jspx customizations alone go here -->
<namespace path="/pages" metadata-store-usage="WebCenterFileMetadataStore">
<namespace-restriction type="CUSTOMIZATIONS"/>
</namespace>
<!-- Your pagedef customizations alone go here -->
<namespace path="/pageDefs" metadata-store-usage="WebCenterFileMetadataStore">
<namespace-restriction type="CUSTOMIZATIONS"/>
</namespace>
