This Action class process any actions that are made by the user.
+ *When the following buttons are pressed:
+ * NoticeboardConstants.BUTTON_BASIC, NoticeboardConstants.BUTTON_ADVANCED,
+ * NoticeboardConstants.BUTTON_INSTRUCTIONS or NoticeboardConstants.BUTTON_DONE,
+ * they switch between the tabs, but before doing so, they copy the values
+ * in the form (only if they are not null) and place them in the
+ * equivalent formbean properties (session scope). This is done so because the form
+ * is spread across two pages (basic and instructions, in Noticeboard tool, there is
+ * no Advanced page). It might be strange that all buttons forward to the same path,
+ * but the formbean property "method" keeps a track of what button was pressed.
+ * So when control returns to the jsp, it will determine the value of method and
+ * show the appropriate page.
The button NoticeboardConstants.BUTTON_UPLOAD triggers an upload and will + * upload either a file of type "ONLINE" or "OFFLINE", to the content repository + * and will save the file details (filename, toolcontent id, uuid, and filetype). + * It will also conduct checks + * to see whether the same file (and same type) has been uploaded or not. + * If the same file has been uploaded (to the same noticeboard instance, ie. same + * tool content id) then, it will delete the file from the content respository + * and delete that particular entry in the table, and then it the new version + * will be uploaded to the content repository and a new entry will be saved into + * the database. It then updates the attachment map that was initially setup + * by NbAuthoringStarterAction.
The button NoticeboardConstants.LINK_DELETE will trigger the deleteAttachment + * action which will delete a file from the content repository, and the entry from + * the attachment table.
+ * + *The save method persist the values of the formbean properties + * title, instructions, onlineInstructions and offlineInstructions to + * the database
