custom converter and BooleanCheckbox doens´t work together

[David Steinkopff <da...@googlemail.com>]

Hello,

I try to set up a custom converter for a BooleanCheckbox, because I
need custom boolean values in my bean.

public class BooleanConverter implements Converter {

    public BooleanConverter() {}

    public Object getAsObject(FacesContext facesContext, UIComponent
uIComponent, String string) throws ConverterException {
        if(Boolean.parseBoolean(string)) {
            return "Y";
        }
        return "N";
    }

    public String getAsString(FacesContext facesContext, UIComponent
uIComponent, Object object) throws ConverterException {
        if("Y".equals(object)) {
            return Boolean.toString(true);
        }
        if("N".equals(object))
            return Boolean.toString(false);
        throw new ConverterException();
    }

}

I make an entry in my faces-config and add it with <f:converter
converterId="myconverter"/>

If I modify my checkbox and make a request, getAsObject will never
called. If I reload the page with the checkbox will getAsString called
with the String "0" or "1".

Give it any possiblity to say JSF save me "Y" for true and "N" for false.

regards
David

Hello,

unfortunately, selectBooleanCheckbox does not give converters any chance
to be called and assume backing property is of type boolean or
java.lang.Boolean.
>From HtmlCheckboxRendererBase, around line 300:

    public Object getConvertedValue(FacesContext facesContext,
            UIComponent component, Object submittedValue)
            throws ConverterException {
       
org.apache.myfaces.shared_impl.renderkit.RendererUtils.checkParamValidity(facesContext,
component, null);
        if (component instanceof UISelectBoolean) {
            return submittedValue;

while this is, as far as i know, consistent with JSF release
implementation i don't see in specs where it should not call converter.
On the other hand, the Renderer api clearly states that calling
converter is "optional" :(

what about using <h:selectOneRadio>and <f:selectItem> instead?
