    rich:select + a4j:ajax

    Rui Albuquerque Newbie

      Hi, so i'm trying to make two rich:selects work dinamicaly, depending on what i chose in the first rich select. The class Day has two atributes: a string with the day and a list of strings with the hours

       

      I want to chose the day from the first combo box, and then i want the other two comboboxes to be populated with the hours of the chosen day.

       

      The value changed method:

      [code]

      LinkedList<String> hours = day.getHoursOfDay();.

      youcan = true

      [/code]

       

      Can anyone help me? Because when i select the day in the first combobox, the second ones aren't rendered...

       

      Bellow goes the xhtml code

       

      [code]

      <a4j:outputPanel >

                                              <rich:panel appendID = "false" id = "out" rendered="true}">

                                                        <h:form id = "calendarform">

                                                                  <h3>From:</h3>

       

                                                                  <rich:select value="#{TemperatureBean.day}"

                                                                                      enableManualInput="false" defaultLabel="Choose Day Here"

                                                                                      style="Width:150px" valueChangeListener = "#{TemperatureBean.valueChanged}">

                                                                            <f:selectItems value="#{TemperatureBean.getDays()}" var="day"

                                                                                      itemLabel="#{day.getDay()}" />
