for following jsp, i can retrieve the data from KeywordcategoryAction for no
problem,
the contents of retrieved list is
Motor
Electrical
Temperature
<s:url id="remoteurl" action="KeywordcategoryAction"/>
<sj:select
href="%{remoteurl}"
id="language"
onChangeTopics="reloadsecondlist"
name="language"
list="languageObjList"
listKey="myKey"
listValue="myValue"
emptyOption="true"
headerKey="-1"
headerValue="Select Category"
value="why"
/>
but, the default value(why) as defined from KeywordcategoryAction did not
working at all
i change from value="why" to value="%{why}', but still not working,
the souce code is at following
public class ListValue {
private String myKey;
private String myValue;
/* ....set/get here */
}
public class Keywordcategory0Action {
....
private List<String> languageList;
private List<ListValue> languageObjList;
private Map<String, String> languageMap;
private List<String> reloadList;
private String language;
ArrayList<String> main_categorys;
....
/* set/get here */
main_categorys= .../* get return from databsse */
languageList = new ArrayList<String>();
languageObjList = new ArrayList<ListValue>();
languageMap = new HashMap<String, String>();
for (String m: main_categorys) {
languageList.add(m);
languageMap.put(m,m);
languageObjList.add(new ListValue(m, m));
}
reloadList = new ArrayList<String>();
why="Temperature";
return success;
}
public String getJSON() throws Exception { return execute(); }
please advise,
thanks in advance
