how to make a rich:message(s) with hyperlink

[bcn]

In rich:message and rich:messages all characters are escaped, so a hyperlink shows as plain text, as in h:message(s).

For standard JSF there are solutions around like this:

http://stackoverflow.com/questions/3356546/embedding-a-link-or-other-html-in-a-jsf-message

I digged into the RichFaces code, but I am not sure how to achieve it for rich:message.

Do I have to overwrite org.richfaces.renderkit.MessageRendererBase?

It would be nice to have the escape attribute in rich:message by default.

There is an old feature request for RichFaces 3:

http://community.jboss.org/thread/145789?tstart=0

But since I cannot wait for this, I need a solution now.

Thanks in advance

The relevant RichFaces jira issue is: https://issues.jboss.org/browse/RF-8226

I remeber asking that question on stack overflow...

I ended up implementing a custom renderer for the vanilla jsf solution:

@FacesRenderer(componentFamily="javax.faces.Messages", rendererType="javax.faces.Messages")
public class MessagesRenderer extends com.sun.faces.renderkit.html_basic.MessagesRenderer {


    @Override
    public void encodeEnd(FacesContext context, UIComponent component) throws IOException {
        ResponseWriter oldWriter = context.getResponseWriter();
        ResponseWriter newWriter = new NoEscapeWriter(oldWriter, oldWriter.getContentType(), oldWriter.getCharacterEncoding());
        context.setResponseWriter(newWriter);
        super.encodeEnd(context, component);
        context.setResponseWriter(oldWriter);
    }


    @Override
    public void encodeBegin(FacesContext context, UIComponent component) throws IOException {
        ResponseWriter oldWriter = context.getResponseWriter();
        ResponseWriter newWriter = new NoEscapeWriter(oldWriter, oldWriter.getContentType(), oldWriter.getCharacterEncoding());
        context.setResponseWriter(newWriter);
        super.encodeBegin(context, component);
        context.setResponseWriter(oldWriter);
    }
}

and registered it via the faces-config:

    <render-kit>
        <renderer>
            <component-family>javax.faces.Messages</component-family>
            <renderer-type>javax.faces.Messages</renderer-type>
            <renderer-class>
        ca.triumf.mis.qms.workrequest.jsf.renderer.MessagesRenderer
            </renderer-class>
        </renderer>
    </render-kit>

The same approach should work in this case.  Just override the RichFaces classes, instead of the mojarra ones.

This is a non-invasive (in that you don't have to change richfaces code) solution, which is good.  You can drop this code from your project as soon as it becomes available in RichFaces.

I tried

import java.io.IOException;

import javax.faces.component.UIComponent;

import javax.faces.context.FacesContext;

import javax.faces.context.ResponseWriter;

import javax.faces.context.ResponseWriterWrapper;

import javax.faces.render.FacesRenderer;

import org.richfaces.renderkit.html.HtmlMessagesRenderer;

@FacesRenderer(componentFamily="javax.faces.Messages", rendererType="javax.faces.Messages")

public class NoEscapeMessagesRenderer extends HtmlMessagesRenderer {

  @Override

  public void encodeEnd(FacesContext context, UIComponent component) throws IOException {

      ResponseWriter oldWriter = context.getResponseWriter();

      ResponseWriter newWriter = new NoEscapeWriter(oldWriter);

      context.setResponseWriter(newWriter);

      super.encodeEnd(context, component);

      context.setResponseWriter(oldWriter);

  }

  @Override

  public void encodeBegin(FacesContext context, UIComponent component) throws IOException {

      ResponseWriter oldWriter = context.getResponseWriter();

      ResponseWriter newWriter = new NoEscapeWriter(oldWriter);

      context.setResponseWriter(newWriter);

      super.encodeBegin(context, component);

      context.setResponseWriter(oldWriter);

  }

    class NoEscapeWriter extends ResponseWriterWrapper {

        ResponseWriter originalWriter;

        public NoEscapeWriter(ResponseWriter originalWriter) {

            this.originalWriter = originalWriter;

        }

        @Override

        public ResponseWriter getWrapped() {

            return originalWriter;

        }

        @Override

        public void writeText(Object text, UIComponent component, String property)

                throws IOException {

            String string = String.valueOf(text);

            String escape = (String) component.getAttributes().get("escape");

            if (escape != null && !Boolean.valueOf(escape)) {

                super.write(string);

            }

            else {

                super.writeText(string, component, property);

            }

        }

    }

}

and registered it in faces-config.xml, but it is never used when I produce rich:messages or rich:message.

Am I extending the wrong class?

Thanks

In richfaces use this code below:

	<render-kit>
	<renderer>
	<component-family>org.richfaces.component.RichMessages</component-family>
	<renderer-type>org.richfaces.RichMessagesRenderer</renderer-type>
	<renderer-class>com.sample.EscapableMessagesRenderer</renderer-class>
	</renderer>
	</render-kit>

public class EscapableMessagesRenderer extends org.richfaces.renderkit.html.HtmlRichMessagesRenderer
