Hi,

that's a standard iterator problem, no EJB3 issue ;-):
for(RoleFunction roleFunction:this.listRoleFunctions){
  | 			...
  | 			this.listRoleFunctions.remove(roleFunction);
You remove an item from the list over which you iterate. Use this "for (int index = this.listRoleFunctions.size() - 1; index >= 0; index--)" to avoid this.

Best regards

Wolfgang
