Scenario:
	Homepage XSP generates an initial form.
	Parameters are set.
	I would like to then access my sub-sitemap URI space depending
on the parameter values.
	Ex.
	eval/first/first if parameter value is 1
	eval/second/second if parater value is 2

	Is this possible by doing the following?

Here is my latest try:

    <map:pipeline>
	...
      <map:select type=3D"request-parameter">
        <map:parameter name=3D"parameter-name" value=3D"test-name"/>
        <map:when test=3D"">
          <map:redirect-to session=3D"true" uri=3D"eval/home/form"/>
        </map:when>
        <map:when test=3D"1">
          <map:redirect-to session=3D"true" uri=3D"eval/first/first"/>
        </map:when>
        <map:when test=3D"2">
          <map:redirect-to session=3D"true" uri=3D"eval/second/second"/>
        </map:when>
	  <map:otherwise>
          <map:redirect-to session=3D"true" uri=3D"eval/home/form"/>
        </map:otherwise>
      </map:select>

      <map:match pattern=3D"*/*">
        <map:generate type=3D"serverpages" src=3D"logic/{1}/{2}.xsp"/>
        <map:transform src=3D"style/menupage.xsl">
          <map:parameter name=3D"toc-file" =
value=3D"../content/toc.xml"/>
          <map:parameter name=3D"css-stylesheet" value=3D"default.css"/>
          <map:parameter name=3D"base-url" value=3D"/cocoon/eval"/>
        </map:transform>
        <map:serialize/>
      </map:match>
	...
    </map:pipeline>

I get the following compile error:

org.apache.cocoon.ProcessingException: Language Exception:

Any thoughts?
