Grails parameter passing -

basically using code below debugging. renders null , cannot figure out reason. , way else statement executed @ point. @ first didnt have save method thought might fix issue. may have scope of domains? of have them set session scope: class info { static scope = "session" string name string smokingstatus string[] symptom static constraints = { } }

        else{//query did not find patient id             def patinfo = new info()             patinfo.name = "dennis"             patinfo.smokingstatus = "former smoker"             patinfo.symptom = ["cough"]             patinfo.save()             redirect(action:"display", params: [patinfo:patinfo])             //redirect(action:"login")             //return login action ,          }     }    }  def display(){     render params.name  } 

thanks appreciated.

you assign value of patinfo variable name patinfo in display action must use:

render params.patinfo 

by example if use following:

redirect(action:"display", params: [duck:patinfo]) 

you must use:

render params.duck
