I am trying to put link in the error messages produced by JSF. For this I am using the custom renderer, it works(clicking the error, focuses the respective input field) but the problem is , all the form values gets empty. ie when error occurs, all the input fields get empty. Any suggestion will be appreciated.

package custom;

public class CustomErrorRenderer extends Renderer {

@Override @SuppressWarnings("unchecked") public void encodeEnd(FacesContext context, UIComponent component) throws IOException { ResponseWriter writer = context.getResponseWriter(); writer.startElement("div", component); writer.writeAttribute("id", component.getClientId(context), "id"); writer.writeAttribute("style", "color: red", null); writer.startElement("ul", null); Iterator clientIds = context.getClientIdsWithMessages(); while (clientIds.hasNext()) { String clientId = clientIds.next(); Iterator messages = context.getMessages(clientId); if (!messages.hasNext()) { continue; } String javaScript = "var field = document.getElementById('" + clientId + "');" + "if(field == null) return false;" + "field.focus(); return false;"; writer.startElement("li", null); writer.startElement("a", null); writer.writeAttribute("onclick", javaScript, null); writer.writeAttribute("href", "#", null); while (messages.hasNext()) { writer.writeText(messages.next().getSummary(), null); } writer.endElement("a"); writer.endElement("li"); } writer.endElement("ul"); writer.endElement("div"); } }

This renderer is defined in faces-config.xml: add to base HTML_BASIC renderkit HTML_BASIC HTML_BASIC CustomErrorRenderer javax.faces.Output custom.CustomErrorRenderer custom.CustomErrorRenderer CustomErrorMessages custom.Errors javax.faces.component.UIOutput a tag class:

package custom;

import javax.faces.webapp.UIComponentELTag;

public class CustomErrorTag extends UIComponentELTag {

@Override public String getComponentType() { return "custom.Errors"; }

@Override public String getRendererType() { return "custom.CustomErrorRenderer"; }

}

This is defined in a TLD file:

http://java.sun.com/xml/ns/javaee/web-jsptaglibrary_2_1.xsd" version="2.1"> 1.0 custom http://custom errors custom.CustomErrorTag empty

This goes at the top of the JSP page:

<%@ taglib prefix="custom" uri="http://custom"%>
