Hi, I'm using required variables but i don't understand how it works because i can follow the process without affecting a value to the variable. <start-state name="Saisie de la demande"> | <task blocking="true" name="Saisie de la demande"> | <controller> | <variable access="read,write,required" | name="Description"></variable> | </controller> | </task> | <transition to="Validation Chef de projet" | name="Soumettre"></transition> | </start-state> Another thing, when i generate the forms, the required="true" is not generated on the input field. Can you help ? thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082542#...
