Re: Dynamic Value binding - please help!

[Mike Kienenberger]

You need to assign ValueBinding objects, not strings.

You'd typically do something like this [example borrowed and modified
from another posting]:

   FacesContext context = FacesContext.getCurrentInstance();
  Application app = context.getApplication();

  reportingPeriodsSelectItemsControl.setValueBinding("itemLabel",
app.createValueBinding("#{rptPeriod.reportingDateMonthly}"));

Hi,

I need to create the following construct dynamically in the backing bean:

==============================================================================================
<h:outputText value="Reporting Period"  />
     <h:selectOneMenu
value="#{searchHandler.reportingPeriod.rawDate}"

binding="#{searchHandler.reportingPeriodSelectOneMenuControl}">

         <t:selectItems value="#{searchHandler.reportingPeriods}"
var="rptPeriod"
                itemLabel="#{rptPeriod.reportingDateMonthly}"
itemValue="#{rptPeriod.rawDate}"

binding="#{searchHandler.reportingPeriodsSelectItemsControl}"
         />
     </h:selectOneMenu>

==============================================================================================

So I'm doing the following in my setter:

==============================================================================================
public void setReportingPeriodSelectOneMenuControl(
        HtmlSelectOneMenu
reportingPeriodSelectOneMenuControl) {


    if (reportingPeriods == null){
        logger.debug("reportingPeriods == null: " +
                (reportingPeriods==null) + "building reportingPeriods
list...");
        reportingPeriods =
this.getSearchService().getReportingPeriods();
    }


    //building <t:selectItems>
    if (reportingPeriodsSelectItemsControl == null){
        reportingPeriodsSelectItemsControl =
(UISelectItems) FacesContext

.getCurrentInstance().getApplication().createComponent(
                            UISelectItems.COMPONENT_TYPE);

    }


reportingPeriodsSelectItemsControl.setValue(reportingPeriods);
    reportingPeriodsSelectItemsControl.setVar("rptPeriod");

    String label = null;



    if (DAILY.equals(this.getPeriod())) {
        label = "#{rptPeriod.reportingDateDaily}";
    }else if (MONTHLY.equals(this.getPeriod())) {
        label = "#{rptPeriod.reportingDateMonthly}";
    }


    reportingPeriodsSelectItemsControl.setItemLabel(label);

reportingPeriodsSelectItemsControl.setItemValue("#{rptPeriod.rawDate}");



reportingPeriodSelectOneMenuControl.getChildren().add(reportingPeriodsSelectItemsControl);





    this.reportingPeriodSelectOneMenuControl =
reportingPeriodSelectOneMenuControl;
    logger.debug("setReportingPeriodSelectOneMenuControl()"
+ reportingPeriodSelectOneMenuControl);
}

================================================================================================

Unfortunately, what I am getting in the page is the combo populated with a
bunch of strings: #{rptPeriod.reportingDateMonthly}

What am I missing here to link this variable 'rtpPeriod' to the value
binding expression.  Or should there be a different syntax?

Thanks for you help.
