Hey there,
I tried to extend RichFaces' rich:messages component by making it appear like a popup box and adding a close button to it. Thus, I only need to change the renderer of the component. I managed to get it work programmatically, but I couldn't use my new tag in the xhtml files. It won't render it. Besides, I use Eclipse and an error is shown at the message.xml file that the given DTD is not well formed which is strange because it's exactly the one used by Richfaces CDK.
I include my config files, maybe some of you might have an idea what's wrong with them.
mytag.taglib.xml:
> <facelet-taglib>
> <namespace>http://myurl.com/custcomp</namespace> <tag>
> <tag-name>popmessages</tag-name>
> <source>tags/message.xml</source>
> </tag>
>
> </facelet-taglib>
message.xml (almost exact copy, I only changed the class names)
