kaptcha

[captain_rhino]

I might be going mad but how do I use the 

org.apache.tapestry5.kaptcha.components.KaptchaField
org.apache.tapestry5.kaptcha.components.KaptchaImage

component.  I can see the API docs but is there an example and none of the
compenents aoppear in my project?  Any examples would be appreciated?

I do have the tapx component available in my project.  But the validation of
the input always fails? 

Tml
<form t:id="kaptchaForm">
        <t:errors/>
        <div t:id="kaptchaImage"/>
        <div t:id="kaptchaComponent" image="kaptchaImage"/>
        <input type="submit"/>
</form>

Page
import com.howardlewisship.tapx.core.components.KaptchaField;
import com.howardlewisship.tapx.core.components.KaptchaImage;

public class TestKap {

        @Persist
        @Property
        private boolean inputValue;

        @Component
        private Form kaptchaForm;

        @Component 
        private KaptchaImage kaptchaImage;
        
        @Component(parameters = {"value=inputValue","image=kaptchaImage"})
        private KaptchaField kaptchaComponent;

        public boolean onValidateForm()
        {
                boolean goodValidation = true;

                if (!inputValue)
                {
                        kaptchaForm.recordError("kaptcha value not equals the 
user input!");
                        goodValidation = false;
                }

                return goodValidation;
        }
        
}

Any help/examples would be much appreciated.
