Boolean in a combo with "no selection label"

Question

Does anyone know how to display a boolean value in a combobox with a "no selection label" ? If it's a primitive boolean, false is bound to the control by default. If the property is Boolean it causes Property 'foo' not readable on type java.lang.Boolean

Answer 1

This is my bean:
public class Report {
         private boolean forecast;
         public boolean isForecast() {
                  return forecast;
         public void setForecast( boolean reportForecast ) {
                  this.forecast = reportForecast;
}and this is my jsf page:
<h:selectOneMenu value="#{report.forecast}" required="true" >
         <f:selectItem itemValue="true" itemLabel="yes" />
         <f:selectItem itemValue="false" itemLabel="no" />
</h:selectOneMenu>As I wrote before, I would like yet another option in the input, a "no selection option" with label "Pick one..". With the primitive boolean, the field gets instantied with false by default. When I try to use Boolean type, I get the following error when entering the page:
javax.el.PropertyNotFoundException: /editReport.xhtml @50,108 value="#{report.forecast}": Property 'forecast' not readable on type java.lang.BooleanWhen I try to use autoboxing in accessors (just leave the primitive boolean in the signatures) I get
javax.el.ELException: /editReport.xhtml @50,108 value="#{report.forecast}": Error reading 'forecast' on type pl.alior.creditrating.entity.Report
