Still having problems with SourceTypeAction

[greg.vaco]

I�m still getting the following exception when I use the SourceTypeAction:

org.apache.avalon.framework.configuration.ConfigurationException: Could not get 
class (org.apache.cocoon.acting.sourcetype.SourceTypeAction) for role 
sourcetype on configuration element action

I just refreshed my source from Head (revision 124799), seeded an empty 
project, and followed the example, outlined in the documentation 
(http://forrest.apache.org/docs/dev/your-project.html#adding_new_content_type_2),
 to change the example sitemap as follows:

<map:sitemap xmlns:map="http://apache.org/cocoon/sitemap/1.0";>
  <map:components>
    <map:selectors default="parameter">
      <map:selector logger="sitemap.selector.parameter" name="parameter" 
src="org.apache.cocoon.selection.ParameterSelector"/>
    </map:selectors>
    <map:actions>
      <map:action name="sourcetype" 
src="org.apache.cocoon.acting.sourcetype.SourceTypeAction">
        <sourcetype name="hello-v10">
          <document-declaration public-id="-//Acme//DTD Hello Document 
V1.0//EN"/>
        </sourcetype>
      </map:action>
    </map:actions>
  </map:components>
  <map:pipelines>
    <map:pipeline>
      <map:match pattern="**custom.xml">
        <map:generate src="{project:content.xdocs}{1}custom.xml"/>
        <map:act type="sourcetype" src="{project:content.xdocs}{1}custom.xml">
          <map:select type="parameter">
            <map:parameter name="parameter-selector-test" value="{sourcetype}"/>
            <map:when test="hello-v10">
              <map:transform 
src="{project:resources.stylesheets}/hello2document.xsl"/>
            </map:when>
          </map:select>
        </map:act>
        <map:serialize type="xml"/>
      </map:match>
    </map:pipeline>
  </map:pipelines>
</map:sitemap>


I�m struggling here; so, any help in resolving this problem would be greatly 
appreciated.
