Hi all,
I'm creating a custom converter in order to use smallint database fields with boolean components, such as SelectBooleanCheckBox. I'm doing this because Firebird SQL doesn't have a real boolean type.
I've written a very simple converter:
package frautils.Converters;
import javax.faces.context.FacesContext; import javax.faces.convert.Converter; import javax.faces.component.UIComponent; import javax.faces.convert.ConverterException;
public class intBoolConverter implements Converter {
public static final String CONVERTER_ID ="intBoolConverter"; public Object getAsObject(FacesContext context, UIComponent component,
String newValue) throws ConverterException {
return (newValue.equals("1"); }
public String getAsString(FacesContext context, UIComponent component,
Object value) throws ConverterException {
String s = "0";
if (value.toString().equals("true")) { s = "1"; };
return s;
}...and I've registered this in faces-config.xml:
<converter> <converter-id>intBoolConverter</converter-id> <converter-class>frautils.Converters.intBoolConverter</converter-class> </converter>
..and I'm using that in this way:
<h:selectBooleanCheckbox value="#{lista.FRUITO}">
<f:converter converterId="intBoolConverter"/>
</h:selectBooleanCheckbox>("FRUITO" is a smallint field )
the problem is that the converter class is never being called, and the
application returns this error:java.lang.ClassCastException: java.lang.Integer
at javax.faces.component.UISelectBoolean.isSelected(UISelectBoolean.java:38)
at
net.sourceforge.myfaces.renderkit.html.HtmlCheckboxRendererBase.encodeEnd(HtmlCheckboxRendererBase.java:84)
...etc.......
where am I wrong ?
thanks,
