Hello Volker,
is it solved in the actualy nightly build?
Carsten committed the fix one week ago.

Hello Volker,
is it solved in the actualy nightly build?
I don't want to change something in cocoon blocks because of later 
updates of cocoon.

Thank you.

the problem is a ClassCastException because the code was changed to use a
ServiceSelector, but the configuration uses a ExtendedComponentSelector. I
send you the diff what was changed. You can replace ServiceSelector back to
ComponentSelector and it will work again. It seam that there is no
ExtendedServiceSelector available.

Hello,

I had tried to write my own taglib using the TagTransformer but it
doesn't work. I can't find some informations about it, so I had copied
the example and changed something but it doesn't work. I want to use a
tag  to print out "HELLO WORLD". My changes in detail:

1.) I had written my own class HelloWorldTag:

package foo.bar.taglib;

import org.apache.cocoon.taglib.XMLProducerTagSupport;
import org.xml.sax.SAXException;
import org.xml.sax.Attributes;

public class HelloWorldTag extends XMLProducerTagSupport {

   public int doStartTag(String namespaceURI, String localName, String
qName, Attributes atts)
   throws SAXException {
String hello = "HELLO WORLD";
 this.xmlConsumer.characters(hello.toCharArray(), 0,
hello.length());
 this.getLogger().error("T E X T = " + hello);
 return this.EVAL_BODY;
   }
}

2.) I had created a subproject tagtest containing a xml file tagtest.xml:



 


3.) My sitemap looks as follow:


http://apache.org/cocoon/sitemap/1.0";>



  
 
   tag
 
  




  

 



 

  




3.) In cocoon.xconf I had registered the tag :

   
 
   

4.) After calling http://localhost:8080/cocoon/tagtest the tag 
will not be replaces by "HELLO WORLD". I got the following output -
nothing parsed:


   
   


What is wrong here? Thank you for your help.

PS: I had tried the taglib block it seems it doesn't work, too! Whats
about this block? Is it deprecated?

Stephan
