Hi Ruther,

Say you have 2 selectManyListBox, one is source and another is destination.

Create a property in your backing which is of type Map and bind it to your source selectManyListBox and do the same for destination selectManyListbox. During the initial load the destination one will be empty.

Use Ajax to show the selected item from the source to destination.

Since you are binding the selected value(s) to a property in your backing bean you can easily access the value in another selectManyListBox.

Thanks,
Kumar Saravanan

Hi Kumar Saravanan,
Thanks for your reply.
My problem is I've the SelectItems[] values then how to add or remove the values I didn't find any such method for SelectItem[].I found only length for that.
Please could explain me with a small example.
Here I am sending the code

 public void setSelectedPriceList(SelectItem[] availablePriceList)
  {
    this.selectedPriceList = availablePriceList;
  }
 
  public SelectItem[] getSelectedPriceList()
  {
   
    selectedPriceList = getCpgPriceListDtos()
    return selectedPriceList;
  }
 
  public void setAvailablePriceList(SelectItem[] availablePriceList)
  {
    this.availablePriceList = availablePriceList;
  }
 
  public SelectItem[] getAvailablePriceList()
  {
   
 
    availablePriceList = availablePriceListDtos();
    
        
        return availablePriceList;
  }
  
  public void setAvailablePriceLists(SelectItem[] availablePriceLists)
  {
    this.availablePriceLists = availablePriceLists;
  }
 
  public SelectItem[] getAvailablePriceLists()
  {
    return availablePriceLists;
  }
 
  public void setSelectedpriceLists(SelectItem[] selectedpriceLists)
  {
    this.selectedpriceLists = selectedpriceLists;
  }
 
  public SelectItem[] getSelectedpriceLists()
  {
    return selectedpriceLists;
  }
  
       
  public void movetoSelected(ActionEvent event)
  {
    SelectItem[]  values = new SelectItem[getAvailablePriceList().length - getAvailablePriceLists().length];
        
    availablePriceList=values;
    selectedPriceList = new SelectItem[getAvailablePriceLists().length + getSelectedPriceList().length];
 
    
  }

Here is the jsp code

<t:panelGrid columns="3" cellspacing="0" border="1" width="75%">
   <t:outputText value="Available Price List"/>
   <f:verbatim> </f:verbatim>
   <t:outputText value="Selected Price List"/>
   <t:selectManyListbox  value="#{CreatePriceModelBean.availablePriceLists}" style="width: 300px;">
    <f:selectItems value="#{mybean.availablePriceList}"/>
   </t:selectManyListbox>
   <t:panelGrid columns="1">
    <t:commandButton value=">" actionListener="mybean.movetoSelected" style="width: 50px;"/>
       
      </t:panelGrid>
   <t:selectManyListbox value="#{mybean.selectedpriceLists}" style="width: 300px;">
    <f:selectItems  value="#{mybean.selectedPriceList}"/>
   </t:selectManyListbox>
  </t:panelGrid

Hi Ruther, maybe you could try using Sandbox component selectManyPicklist.
Here you have an example http://www.irian.at/myfaces-sandbox/picklist.jsf.

I hope this helps
