如何在CMFCRibbonBar中更新最近的文件列表?

We have replaced VC++ VS2010 menu application with the CMFCRibbonBar. In the older menu driven version we had created our own user defined class derived from CRecentFileList. We overrode the UodateMenu method to add and delete files from the Recent File List. Now that we are using the CMFCRibbonBar, we are having problems getting the Recent Files list updated in the ribbon. the MRU list is properly updated everytime we open another file, but the Recent File list in the ribbon stays the same. If we close the application, then re-open it the Recent File list is updated properly. Any help will be extremely appreciated. Thank you.We have replaced VC++ VS2010 menu application w
