Radio button issue with list, map, collection, localisation and action class.
Hi,
For a single pair of radio buttons, e.g. "Yes" or "No" without localisation,
the following jsp code seems to be straight forward and will always come out
with true/false returned to the server (localised Yes or No can be received
on the server after user have made choice, but this is not the optimal
solution I want. I want always true/false or 1/0):
<s:radio key="My choice" list="#{true:'Yes', false:'No'}" value="true" />
But:
1. I wan to localise the Yes and No with still true/false to come
out, I failed. I have tried:
list="#{true:'<s:text name="yes"/>', false:'<s:text name="no"/>'}"
or
list="#{true:'${yes}', false:'${no}'}"
list="#{true:%{#yes}, false:%{#no} }}" etc
hoping to access the following getter in the action class:
public String getYes(){
return getText("yes");
}
public String getNo(){
return getText("no");
}
(Can a Struts tag embedded in another Struts tag?)
2. I also failed to set the list value from action class for the
given jsp code. This is what I have tried:
Jsp code:
<s:radio key="My choice" list="yesOrNoList" value="true" />
a. getter method returns a (array) list:
public List<String> getYesOrNoList() {
String[] yesOrNoArray = {getText("yes"),
getText("no")};
return Arrays.asList(yesOrNoArray);
}
b. getter method returns a (map) list:
public List<Map> getYesOrNoList() {
Map[] yesOrNoArray = {new HashMap(), new HashMap()};
yesOrNoArray[0].put(true, getText("yes"));
yesOrNoArray[1].put(false, getText("no"));
return Arrays.asList(translateYesOrNoArray);
}
c. getter method returns a collection:
public Collection<Map> getYesOrNoList() {
Map yesOrNoArray = new HashMap();//, new HashMap()};
yesOrNoArray.put(true, getText("yes"));
yesOrNoArray.put(false, getText("no"));
return yesOrNoArray.values();
}
None of them produced the ideal result for me.
Could any one help please? Much appreciated.

My understanding was wrong - thought it has to be "List". Also did not think
about LinkedHashMap.
Tried also <Integer, String> and working fine. Guess <Boolean, String>
should also work.
Cheers!

At least with String keys, it works fine:
Code in your action:
private Map<String, String> myMap = new LinkedHashMap<String, String>();
..
myMap .put("key1", "Yes");// or getText(..)
myMap .put("key2", "No");
..
public Map<String, String> getMyMap() {
return myMap;
}
JSP:
<s:radio list="myMap" name=".." />

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

You can't nest struts tags so you can't put a <s:text> inside of <s:radio>
tag but you should be able to call getText().
I would try this:
<s:radio key="My choice" list="#{true:getText('yes'), false:getText('no')}"
value="true" />
