             Summary: Problems with "optiontransferselect, attributes 
doubleHeaderKey and doubleHeaderValue"
                 Key: WW-4365
                 URL: https://issues.apache.org/jira/browse/WW-4365
             Project: Struts 2
          Issue Type: Bug
    Affects Versions: 2.3.15.3
            Reporter: Fechner


s:optiontransferselect: Can not remove initial doublelist entries if attributes 
"doubleHeaderKey" and "doubleHeaderValue" are used

Code example:
=============
Action:
package de.dwd.prodkat.action;
import java.util.ArrayList;
import java.util.List;
import org.apache.log4j.Logger;
import com.opensymphony.xwork2.ActionSupport;
import de.dwd.prodkat.model.Keyword;

public class OptionTransferSelectAction extends ActionSupport{
        private static Logger log = Logger.getLogger("log." 
+OptionTransferSelectAction.class.getName());
        private static final long serialVersionUID = 1L;
        private Keyword kw;
        private List<Keyword> leftKwList= new ArrayList<Keyword>();
        private List<Keyword> rightKwList= new ArrayList<Keyword>();

        private List<Integer> selectMetElement=new ArrayList<Integer>();
        private List<Integer> metElement=new ArrayList<Integer>();
        
        public OptionTransferSelectAction(){
                kw =new Keyword();
                kw.setId(1);
                kw.setAnzeige("erster Wert");
                leftKwList.add(kw);
                kw =new Keyword();
                kw.setId(2);
                kw.setAnzeige("zweiter Wert");
                leftKwList.add(kw);
                
                kw =new Keyword();
                kw.setId(20);
                kw.setAnzeige("Vorgabewert");
                rightKwList.add(kw);
        }
        
        public Keyword getKw() { return kw; }
        public void setKw(Keyword kw) { this.kw = kw; }
        public List<Keyword> getLeftKwList() { return leftKwList; }
        public void setLeftKwList(List<Keyword> leftKwList) { this.leftKwList = 
leftKwList; }
        public List<Keyword> getRightKwList() { return rightKwList; }
        public void setRightKwList(List<Keyword> rightKwList) { 
this.rightKwList = rightKwList; }
        public List<Integer> getSelectMetElement() { return selectMetElement; }
        public void setSelectMetElement(List<Integer> selectMetElement) { 
this.selectMetElement = selectMetElement; }
        public List<Integer> getMetElement() { return metElement; }
        public void setMetElement(List<Integer> metElement) { this.metElement = 
metElement; }

        public String execute() { return SUCCESS; }
        public String display() { return NONE; }
}

website (jsp):
==============
Case 1: doubleHeaderKey&doubleHeaderValue
...
<s:form action="resultAction" method="post" >
<s:optiontransferselect
        id="metElement"
        label="Tranfer from List to List (ArrayList of Objekt)"
        name="metElement"
        leftTitle="vorgabe"
        rightTitle="auswahl"
        list="leftKwList"
        listKey="id"
        listValue="anzeige"
        multiple="true"
        headerKey="0"
        headerValue="%{getText('select')}"
        cssClass="input_text_mittel"
        listCssClass="input_text_langExt"       

        doubleList="rightKwList"
        doubleListKey="id"
        doubleListValue="anzeige"
        doubleName="selectMetElement"
        doubleHeaderKey="0"
        doubleHeaderValue="%{getText('select')}"
        doubleCssClass="input_text_mittel"
        doubleListCssClass="input_text_langExt"
/>
 <s:submit key="submit" value="submit"/>
</s:form>
...

Case 2: without doubleHeaderKey and doubleHeaderValue
...
<s:form action="resultAction" method="post" >
<s:optiontransferselect
        id="metElement"
        label="Tranfer from List to List (ArrayList of Objekt)"
        name="metElement"
        leftTitle="vorgabe"
        rightTitle="auswahl"
        list="leftKwList"
        listKey="id"
        listValue="anzeige"
        multiple="true"
        headerKey="0"
        headerValue="%{getText('select')}"
        cssClass="input_text_mittel"
        listCssClass="input_text_langExt"       

        doubleList="rightKwList"
        doubleListKey="id"
        doubleListValue="anzeige"
        doubleName="selectMetElement"
        doubleCssClass="input_text_mittel"
        doubleListCssClass="input_text_langExt"
/>

Problem:
Case1: can not remove initional doublelist entry "Vorgabewert"
Case2: can remove initional doublelist entry "Vorgabewert"
