Sitemap relaod breaks w/ inputmodule and param

           Summary: Sitemap relaod breaks w/ inputmodule and param
           Product: Cocoon 2
           Version: Current CVS
          Platform: PC
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: sitemap components
        AssignedTo: cocoon-dev@xml.apache.org
        ReportedBy: ryanagler@hotmail.com


Whenever a sitemap instance uses both an input module and a sitemap parameter, 
cocoon breaks if the sitemap is subsequently modified.  For example, I have the 
following in my sitemap:

<map:match pattern="*.gif">
   <map:read src="sites{URI:}/images/{1}.gif" mime-type="image/gif" /> 
</map:match>

If I modify and save the sitemap, cocoon will throw:

java.lang.ClassCastException: java.lang.String
	at 
org.apache.cocoon.components.treeprocessor.variables.PreparedVariableRes
olver.dispose(PreparedVariableResolver.java:284)
	at org.apache.cocoon.components.treeprocessor.TreeProcessor.disposeTree

cessor.java:308)
	at org.apache.cocoon.Cocoon.process(Cocoon.java:595)


Note this happens only if BOTH an input module and sitemap parameter are being 
used in the same map:read (or map:generate, map:transform, etc).  For example, 
the following do NOT cause problems:

<map:match pattern="*.gif">
   <map:read src="sites/test.com/images/{1}.gif" mime-type="image/gif" /> 
</map:match>

<map:match pattern="*.gif">
   <map:read src="sites{URI:}/images/img1.gif" mime-type="image/gif" /> 
</map:match>
