Pre select a <s:radio> button in struts 2

Question

This is my radio button code.

<s:radio name="filter" requiredposition="right"
list="#{'STATUS_FILTER_START':'START','STATUS_FILTER_END':'STOP'}" 
 value = "STATUS_FILTER_START"></s:radio>

or

<s:radio name="filter" requiredposition="right"
list="#{'STATUS_FILTER_START':'START','STATUS_FILTER_END':'STOP'}" 
 listValue = "STATUS_FILTER_START" listKey =  "STATUS_FILTER_START"s></s:radio>

But nothing works.
Can somebody help me with this? I dont want html:radio tag.

Answer 1

Set default value in your action class and use that in the OGNL to tell which value to select as default

List<String> filter= new ArrayList<String>();
        filter.add("START");
        filter.add("STOP");


    public List<String> getFilter() {
        return filter;
    }
    public String getDefaultFilterValue(){
        return "STOP";
    }

in your jsp use like

<s:radio label="filter" name="filter" list="filter" value="defaultGenderValue" />

i have used simple ArrayList but you are free to use Map.
