the modules can set the errors messages , but the they can't set the success messages .
and based on this response from tyson the modules can't set success messages http://www.blesta.com/forums/index.php?/topic/3145-flashmessage-or-setmessage-in-gateway/?p=22741
the main need here in the tabs section , when a client/staff make some post/change , if error occur the error is shown , but when is finiched with succes , no message is diplayed .
why not to add new Input::success() , Input::info() , Input::warning() ?
