Page Method for Stream Response to Pagelink

I am trying to stream PDF in response to a pagelink, NOT submit button as in:
http://wiki.apache.org/tapestry/Tapestry5HowToStreamAnExistingBinaryFile

In the above wiki, the method used is "onSubmit"...what would be the corresponding method for pagelink.  


// what method should be used instead of onSubmit to capture pagelink request to this page?

public StreamResponse onSubmit() 
{
  // Create PDF
  InputStream is = PDFGenerator.generatePDF("This is the content of a Dynamically Generated PDF");
  // Return response
  return new PDFStreamResponse(is,"MyDynamicSample");
}



I already tried onAction, onPassivate, etc as per these references:

I'm glad you found that example. 

Here's a different one that solves it with PageLink. The page it links to is PersonFind, which returns a StreamResponse:

Cheers,

It's onActivate():

Object onActivate(...) {
	...
	return streamResponse;
}

In that exact page, see section 7. Stream response.
