Or you could use a LabelValueBean:
LabelValueBean[] schoolIds = new LabelValueBean {
new LabelValueBean("Rio Grande do Sul","RS"),
new LabelValueBean("Santa Catarina","SC"),
new LabelValueBean("Parana","PR")
};
If you make schoolIds a property on your ActionForm
you're able to do this:
<html:select property="schoolId">
<html:options property="schoolIds">
</html:select>
I've always thought naming the options list the plural
of the property I'm trying to set is the most straight
forward naming convention: the user is selecting a
schoolId from a list of valid schoolIds.
If you still want to us a Map, I would use a
LinkedHashMap so the order in which you add the
elements is the same order in which they print out.
