When a Map is iterated, it exposes each entry as a Map.Entry record with attributes ''key'' and ''value''. Selectable item is stored in ''value'' attribute of Map.Entry: + + {{{ + <html:select name="addressForm" property="currentStateCode" size="1"> + <html:optionsCollection name="stateMap" value="value.stateCode" label="value.stateName"/> + </html:select> + }}} + - If you want a listbox to always position to a certain hardcoded value instead of value submitted by user, add ''value'' attribute to <html:select> tag.
