Method Summary

boolean	checkIsAjaxRequest(HttpServletRequest request, ServletResponse response) The indication of an AJAX request depends on the concrete ajax framework.
boolean	handleInvalidSequenceNumber(HttpServletRequest request, ServletResponse response, DialogControl sessionDialogControl, DialogInstanceId dialogInstanceId, java.lang.String webPageUrl, DialogParameterHandlerCallback callback) The sequence number is invalid: the request was from a dialog in an old state or a double submit of the same request.
boolean	handleMissingDialogParameters(HttpServletRequest request, ServletResponse response, DialogControl sessionDialogControl, DialogParameterHandlerCallback callback) This method is called when the dialog parameters, i.e. the dialog id or the dialog instance id, are incomplete. This may be a request to enter the application, a request from a bookmark or a request from a dialog that is closed and should not be recreated automatically.

handleInvalidSequenceNumber

public boolean handleInvalidSequenceNumber(HttpServletRequest request,
                                           ServletResponse response,

                                           DialogParameterHandlerCallback callback)

Description copied from class: DefaultDialogParameterHandler

The sequence number is invalid: the request was from a dialog in an old state or a double submit of the same request. Thus we throw an Exception to avoid double submit or request based on old data. You can override this to display your own dialog. For example see the implementation of this method in the showcase. If you do not use sequence numbers, just return.

Description copied from interface: DialogParameterHandler

The indication of an AJAX request depends on the concrete ajax framework. Please take a look at the request parameters to tell us if we are dealing with an AJAX request.
