Hah! That works, thanks, but now I'm facing a new complication:
#{rptPeriod.reportingDateMonthly} and #{rptPeriod.reportingDateMonthly} doesn't
seem to be mapping to the right field in the underlying bean. Let me
explain...
'rtpPeriod' is a representation of ReportingPeriod bean, instances of which
populate the collection behind <t:selectItems> component. These
ReportingPeriod beans have 3 properties for display, each formatted
differently, and set by Spring-based DAOlike this:
public void setReportingDate(Date reportingDate) {
//logger.debug("set reporting date to: " + reportingDate);
this.reportingDate = reportingDate;
this.setReportingDateDaily(new SimpleDateFormat("MMM dd
yyyy").format(reportingDate));
this.setReportingDateMonthly(new SimpleDateFormat("MMM
yyyy").format(reportingDate));
this.setRawDate(new
SimpleDateFormat("MM/dd/yyyy").format(reportingDate));
}
What I see on the page though, is a combo box with the content populated in the
following manner:
03/01/2007
02/01/2007
01/01/2007, etc.
That is instead of using #{rptPeriod.reportingDateMonthly} or
#{rptPeriod.reportingDateDaily}, #{rtpPeriod.rawDate} seems to be used.
Here is my current code:
=====================================================================================================================================
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");
if (DAILY.equals(this.getPeriod())) {
reportingPeriodsSelectItemsControl.setValueBinding("itemLabel",
FacesContext.getCurrentInstance().getApplication()
.createValueBinding(
"#{rptPeriod.reportingDateDaily}"));
}else if (MONTHLY.equals(this.getPeriod())) {
reportingPeriodsSelectItemsControl.setValueBinding("itemLabel",
FacesContext.getCurrentInstance().getApplication()
.createValueBinding(
"#{rptPeriod.reportingDateMonthly}"));
}
reportingPeriodsSelectItemsControl.setValueBinding("itemValue",
FacesContext.getCurrentInstance().getApplication().createValueBinding("#{rptPeriod.rawDate}"));
reportingPeriodSelectOneMenuControl.getChildren().add(reportingPeriodsSelectItemsControl);
this.reportingPeriodSelectOneMenuControl =
reportingPeriodSelectOneMenuControl;
logger.debug("setReportingPeriodSelectOneMenuControl()" +
reportingPeriodSelectOneMenuControl);
}
}
=====================================================================================================================================
ReportingPeriod bean is also registered as a managed-property of the backing
bean on the faces-config.xml if it makes any difference.
Thanks again!!!

Subject: Re: Dynamic Value binding - please help!
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}"));
