Re: [TRINIDAD] How to bind constant values in selections? Or bind Enums to the itemValue.

[Andrew Robinson <an...@gmail.com>]

public enum Gender { MALE, FEMALE }

<tr:selectOneChoice label="Gender"  value="#{person.gender}" required="true">
 <f:selectItem itemLabel="#{text['person.genderMale']}" itemValue="MALE"/>
 <f:selectItem itemLabel="#{text['person.genderFemale']}" itemValue="FEMALE"/>

That may work in 1.2, I cannot remember. I always used Seam to work with enums:
http://docs.jboss.com/seam/2.0.1.GA/reference/en/html/controls.html

See <s:convertEnum> and <s:enumItem>
