SourceWritingTransformer not creating file until end of pipeline?

[Hugh Field-Richards]

Hi 

I have a pipeline whose main parts are

		<map:transformer name="write-source"
logger="sitemap.transformer.write-source"
src="org.apache.cocoon.transformation.SourceWritingTransformer"/>


      <map:match pattern="sendDoc.html">
<map:generate type="jxt" src="sendDoc-en.xml" />
<map:act type="auth-protect">
<map:parameter name="handler" value="adminHandler"/>
<map:parameter name="application" value="adminApp"/>

<map:transform type="session" />
...
<map:transform type="write-source"/>
<!-- Add to data base -->
<map:transform type="add2DB"/>
...
<map:transform type="encodeURL"/>
<map:serialize type="html"/>
</map:act>
</map:match>

I have found that file that is created by the "write-source" does not
exist for my add2DB transformer until the pipeline has run its course.
I have put in the following in add2DB to force a delay to ensure that
a simple delay is not the problem with SourceWritingTransformer:

long st = System.currentTimeMillis();
long t = st;
while ( !( new File( filePath ).exists() ) ) {
if ( t - st > 10000 ) {
throw new Exception( "File error: file '" + filePath + "' does not exist" );
}
t = System.currentTimeMillis();
}

The effect is to wait for 10 seconds before the pipeline is completed
and the file appears in the file system with the above Exception being
raised, which shows that the file is not created while the pipeline is
still working. I am using BSD Unix on a Mac G4. 

I guess the problem is that the file is not being flushed/closed within
the SourceWritingTransformer. Any help here would be gratefully received.

TIA
