Re: ZipValidator that worked in 3.0.3 doesn't work in 4.0

[Matt Raible]

Thanks - that appears to work. However, now I've discovered that
validation doesn't work at all.  In Tapestry 3.0.3, I was using a
custom ValidationDelegate that I found in Tapestry in Action. 
Unfortunately, it doesn't seem to work in Tapestry 4.  I'm setting it
in my page-specification using:

<bean name="delegate" class="org.appfuse.webapp.action.Validator"/>

Is there a different way to set this in 4.0?

The other problem I have with this Validator in 4.0 is there's now a
nested <label> inside the <label> I'm writing.  Is it possible to set
the "required" class on the <label> that Tapestry writes?

public class Validator extends ValidationDelegate {
    private static final long serialVersionUID = 6658594142293597652L;

    public void writeLabelPrefix(IFormComponent component,
                                 IMarkupWriter writer, IRequestCycle cycle) {
        writer.begin("label");

        if (isInError(component)) {
            writer.attribute("class", "error");
        } else {
            writer.attribute("class", "required");
        }

        writer.print(" * ");
    }

    public void writeLabelSuffix(IFormComponent component,
                                 IMarkupWriter writer, IRequestCycle cycle) {
        Locale locale = cycle.getEngine().getLocale();
        String marker = (locale.equals(Locale.FRENCH)) ? " :" : ":";
        writer.print(marker);
        writer.end();
    }

    public void writeAttributes(IMarkupWriter writer, IRequestCycle cycle,
                                IFormComponent component, IValidator
validator) {
        if (isInError()) {
            writer.attribute("class", "error");
        }
    }

    public void writeSuffix(IMarkupWriter writer, IRequestCycle cycle,
                            IFormComponent component, IValidator validator) {
        if (isInError(component)) {
            writer.printRaw("&nbsp;");
            writer.begin("img");

            String ctxPath = cycle.getInfrastructure().getContextPath();
            writer.attribute("src", ctxPath + "/images/iconWarning.gif");
            writer.attribute("class", "validationWarning");
            writer.attribute("alt",
cycle.getPage().getMessages().getMessage("icon.warning"));
            writer.end();

            writer.printRaw("&nbsp;");

            IFieldTracking tracking = getComponentTracking();
            IRender render = tracking.getErrorRenderer();
            String error = "";

            if (render instanceof RenderString) {
                error = ((RenderString) render).getString();
            }

            writer.begin("span");
            writer.attribute("class", "fieldError");
            writer.printRaw(error);
            writer.end();
        }
    }
}

Thanks,

Matt
