Applying SourceWritingTransformer to file used in pipeline

[Remmerie Bart <Ba...@elia.be>]

It appears to be impossible to use the SourceWriting transformer to a file
that is in use by the pipeline.
Does anyone have a workaroud / alternative for this ?

A bit more details:

Below is my code (which is not working).
When I try to write to writeTest.xml, I get the following error:

org.apache.cocoon.ProcessingException: Could not process your document.:
java.io.IOException: Could not rename
C:\cocoon-2.1\build\webapp\samples\testDir\writeTest.xml.tmp to
C:\cocoon-2.1\build\webapp\samples\testDir\writeTest.xml
cause: java.io.IOException: Could not rename
C:\cocoon-2.1\build\webapp\samples\testDir\writeTest.xml.tmp to
C:\cocoon-2.1\build\webapp\samples\testDir\writeTest.xml

I have the following snippet in my pipeline

   <map:match pattern="write">
    <map:generate src="writeTest.xml"/>
    <map:transform type="write-source"/>
    <map:serialize type="xml"/>
   </map:match>

and writeTest.xml contains the following:
 <page>
   <source:write xmlns:source="http://apache.org/cocoon/source/1.0">
     <source:source>writeTest.xml</source:source>      
     <source:fragment><page>
       <title>Hello World</title>
       <content>
         <p>This is my first paragraph.</p>
       </content>
     </page></source:fragment>
   </source:write>
 </page>


Thanks & Regards,
Bart

Of course it is so, you must have in mind that the file content is 
streamed! And what should be the use case for writing a file *while* you 
are reading it?

I guess FlowScript with calls to different pipelines.
