Flash Notification not displayed

[changwuf31]

Most of the time, when saving resources, the flash notifications are not displayed.

The only case the notification will be displayed, is on the singleton page, like "Setting"

//set
actionArgument.SkipDefaultResponse = true
//before
actionArgument.Context.Flash("message test", "message type")

@jinzhu This can be closed.
