how to retrieve selected items in a picklist

[beornotobe]

Hi everybody, i'm a newbie in richfaces, i have a problem to retrieve selected items in a picklist

this is the code of jsp :

                                   <rich:pickList  value="#{configurePlansTarifaires.chosenListParamIN}">                       
                                            <f:selectItem itemLabel="Type Modem" itemValue="modem"/>
                                            <f:selectItem itemLabel="Région" itemValue="region"/>
                                        </rich:pickList>

an a4j commandbouttin to retrieve selectedItems and process the results

                              <a4j:commandButton id="confirmboutton" value="Valider" styleClass="boutonStandard" type="submit"                                                        actionListener="#{configurePlansTarifaires.parametrerIN}" >
                                        </a4j:commandButton>                       

in my backing bean i create a list of String with getters and setters :

                                   private List<String> chosenListParamIN = new ArrayList<String>();

when i try to retrieve results

                                   public void parametrerIN(ActionEvent event)
                                        {
                                                 if(chosenListParamIN().isEmpty())
                                                 {
                                                     System.out.println("Empty");
                                                      }    

                                             }

it's allways empty i don't know why

is anyone have an idea please, i need help

I would reccomend to use action - <a4j:commandButton ...... action="#{configurePlansTarifaires.parametrerIN}"

thanks for reply, but even with action, the list is allways empty

that's a new track, my picklist is defined inside an a4j:outputpanel

                                  <a4j:outputpanel id="tarifparameters"> 

                                    <rich:pickList   value="#{configurePlansTarifaires.chosenListParamIN}">                        
                                            <f:selectItem  itemLabel="Type Modem" itemValue="modem"/>
                                             <f:selectItem itemLabel="Région" itemValue="region"/>
                                         </rich:pickList>

                              </a4j:outputpanel>

and my commandbutton is outside outputpanel, i find that when i make my picklist outside the outputpanel it's works fine.

so i need the picklist inside the outputpanel because it's a result of ajax request.

i tried to place my commandbutton into the outputpanel but in this case the button doesn't work at all.

anyone have an idea plz
