Hi Henry,
I think you have a mistake in the config (like renderer-type).
here is a *simple* extended version of MessageRenderer.
Java class:
package net.wessendorf.trinidad;
import java.io.IOException;
import javax.faces.component.UIComponent;
import javax.faces.context.FacesContext;
import javax.faces.context.ResponseWriter;
import org.apache.myfaces.trinidad.bean.FacesBean;
import org.apache.myfaces.trinidad.component.core.output.CoreMessage;
import org.apache.myfaces.trinidad.context.RenderingContext;
import org.apache.myfaces.trinidadinternal.renderkit.core.xhtml.MessageRenderer;
public class CustomMessageRenderer extends MessageRenderer
{
public CustomMessageRenderer()
{
this(CoreMessage.TYPE);
}
protected CustomMessageRenderer(FacesBean.Type type)
{
super(type);
}
@Override
protected void encodeAll(
FacesContext context,
RenderingContext rc,
UIComponent component,
FacesBean bean) throws IOException
{
ResponseWriter writer = context.getResponseWriter();
writer.startElement("div", null);
writer.write("BLAH");
writer.endElement("div");
super.encodeAll(context, rc, component, bean);
}
}
required xml:
<render-kit>
<render-kit-id>org.apache.myfaces.trinidadinternal.core</render-kit-id>
<renderer>
<component-family>
org.apache.myfaces.trinidad.Message
</component-family>
<renderer-type>
org.apache.myfaces.trinidad.Message
</renderer-type>
<renderer-class>
net.wessendorf.trinidad.CustomMessageRenderer
</renderer-class>
</renderer>
</render-kit>
(note that now <tr:message /> is using this custom renderer.
