I recieve the following error
with the code below
$this->createUrl('message/compose', array("id"=>$id,'VesselId'=>$VesselId,'PP_Result'=>'true'));
which generates
[b]
http://localhost/ application/message/compose/77/46/true
[/b]
due to configuration file
'message/compose/<id:[0-9]+>/<VesselId:[0-9]+>/<PP_Result:[true,false,unknown]>/'=>'message/compose',
