Keep the state or value of a DropDownChoice and TextField both inside a ListView

[Bruno Moura]

I have implemented a listView and every time that a new item is added in
this ListView the values inserted in the textField and selected in a
DropDownChoice are lost.

The following pictures show what's happen before and after add a new
ListView item:

And after Add a new item:

[image: Imagem inline 1]

I'm implemented the code bellow:




      var listData = workSheetDAO.listWorkSheetUser(selectedUser,
beginDate, endDate)

      var lbPeriodTotal = new Label("periodTotal")
      lbPeriodTotal.setOutputMarkupId(true)
      add(lbPeriodTotal)

      add(new ListView[WorkSheet]("listWorkSheet", listData) {

        override protected def onBeforeRender() {
          super.onBeforeRender()
        }

        def populateItem(item: ListItem[WorkSheet]) = {
          var workSheet = item.getModelObject()

          item.add(new LinkDate("initDate", workSheet, 1))
          item.add(new LinkDate("endDate", workSheet, 1))

          item.add(new TextField("description"))

          val listCustomer: java.util.List[Customer] =
customerDAO.listCustomers

          item.add(new DropDownChoice("customerSelection", listCustomer,
new ChoiceRenderer[Customer]("id")))

          if (workSheet.endDate == None) {
            item.add(new Label("total", ""))
          } else {
            var period = new Period(workSheet.initDate,
workSheet.endDate.get)
            periodTotal = periodTotal.plus(period)
            lbPeriodTotal.setDefaultModel(new
Model(periodTotal.toPeriod().normalizedStandard().toString(getFormatter())))
            period = period.normalizedStandard()
            item.add(new Label("total", period.toString(getFormatter())))
          }

       }
    }

    private class LinkDate(id: String, workSheet: WorkSheet, type: Int)
extends Link[String](id) {

      setEnabled(false)
      add(new Label("label", new Model[String]() {
        override def getObject(): String = {
          var result = ""
          if (type == 1) {
              result = workSheet.initDate.toString("dd/MM/YYYY HH:mm:ss")
          } else
              result = workSheet.endDate.toString("dd/MM/YYYY HH:mm:ss")
          return result
        }
      }))

      def onClick() {}
    }


The only values preserved are the values of the labels.

Please, someone could help me, thanks
