In several days ago, i just know there is valueMessagePrefix attribute of g:select. It’s very useful in some cases, for example, we want to display day of week (from Mon to Sun); this code will do.
in gsp:
<g:select name="dayOfWeek" from="${['1', '2', '3', '4','5','6','7']}" valueMessagePrefix="label.dayofweek" />
in messages.properties :
label.dayofweek.1=Mon label.dayofweek.2=Tue label.dayofweek.3=Wed label.dayofweek.4=Thu label.dayofweek.5=Fri label.dayofweek.6=Sat label.dayofweek.7=Sun
