You shouldn't call your var 'mess' if your list is called 'mess' aswell. That might cause the problem, but I'm not sure about that. Use something different that makes the code more readable. Also check if the list you create in your controller is not empty.

status is your row ID

 <g:each in="${mess}" var="myMess" status="i">



${myMess.id} is what you want to show

${myMess.name} is what you want to show

where name is a defined domainClass value in Message domainClass
