Not sure if there is. I would suggest a couple of approaches:
1) Use XSLT to transform the result of the SWT into your desired page
for the user (could include a <meta http-equiv="refresh"> style redirect)
2) Use the Flow processPipelineTo to write your source, and then send
another page using sendPage

With a serious hack, try using:
processPipelineTo("URL", new
Packages.org.apache.cocoon.bean.CocoonWrapper.NullOutputStream());
Only I wouldn't like to rely on the existence of that implementation of
a null output stream. If you like this approach, you might want to make
your own (it isn't hard).

Dear Upayavira,
thank you for your help
this approach works fine for me.
As you suggested,
i used processPipelineTo with the outputstream of a resolver of a new file
(in which i capture the output of the WST pipeline), so the flow scripts
can continue.
Best Regards
Gianluca

Well, having just replied, I realised that perhaps we're doing this all
wrong. Why not do:
var resolver =
cocoon.getComponent(Packages.org.apache.excalibur.source.SourceResolver.ROLE);
var source = resolver.resolveURI("URI for your modifiable source");
var outputstream = source.getOutputStream();
cocoon.processPipelineTo("page", outputstream);
resolver.release(source);
That way you don't need the SWT at all.

Sounds good,
i'm calling the SWT pipeline from flow with redirectTo.
I tried also processPipelineTo from flow, but i don't know how to setup a
correct outputstream parameter.
A null outputstream parameter is invalid. I don't need to process the output
of the swt.
Do you have any example how to use processPipelineTo?
Thank you
Gianluca
