    Extending rich:messages

    Balázs Németh Newbie
      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:
      <?xml version="1.0"?>
      <!DOCTYPE facelet-taglib PUBLIC
              "-//Sun Microsystems, Inc.//DTD Facelet Taglib 1.0//EN"
          > <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)
          <?xml version="1.0" encoding="UTF-8"?>
          <!DOCTYPE components PUBLIC "-//AJAX4JSF//CDK Generator config/EN"

          This could be done using combination of existent components inside the custom facelet rather than creation of component.. should be something like:

           

          <outputPanel ajaxRendered="true">
               <modalPanel showWhenRendered="#{facesContext.maximumSeverity!=null}">
                    <messages/>
                    <button value="Close"/>
               </modalPanel>
          </outputPanel>

            thanks for your response!

            so what i should do is onclick="#{rich:component('errorPanel')}.hide()" on the close button, right? but is there a way to substitute the hide() method with a jQuery-sh fadeOut somehow?

             

            and I think you solution would work for now, but if we go back to the original problem, do you have any idea how to solve that one?

             

            the strange thing is that eclipse tells me:

             

            The errors below were detected when validating the file "component-config.dtd" via the file "message.xml".  In most cases these errors can be detected by validating "component-config.dtd" directly.  However it is possible that errors will only occur when component-config.dtd is validated in the context of message.xml.

             

            and more detailed:

            The markup declarations contained or pointed to by the document type declaration must be well-formed.

             

            I use this one:

             

            <?xml version="1.0" encoding="UTF-8"?>
            <!DOCTYPE components PUBLIC "-//AJAX4JSF//CDK Generator config/EN"

             

            I think it's somewhat strange....

             

            cheers,
