Subject RE: Radio button issue with list, map, collection, localisation and action class.
Date Wed, 04 Nov 2009 16:36:13 GMT
Greg and Samuel,

Thank you very much indeed for your quick response. Your suggestions are
indeed working!

Just out from my curiosity, would it be possible to achieve the same effect
by the code from the action class (I have got no more clue since all my
effort failed)? 

The documentation (2.1.8, radio) said "If the list is a Map (key, value),
the Map key will become the option 'value' parameter and the Map value will
become the option body."

But when I tried my "map" list, the "key=value" were shown together rather
than value were shown and the key were sent to the server after choice is
made. 

Cheers, Q

This should also work:

<s:text var="yes" name="yes"/>
<s:text var="no" name="no"/>
<s:radio key="My choice" list="#{true:#yes, false:#no}" value="true" />
