This is my superclass for xsl:fo reports that generate to pdf.
HTH,

super(context);

So, normally a WOHyperlink's action returns a WOComponent; for the same
page, it's null.
However, I'm clicking on a WOHyperlink which is linked to an action.
The
action's code will generate an XML file, transform it via xsl-fo to
PDF,
and I want to return the PDF. I'm not using ReportMill or anything
fancy
here, just vanilla WO, plus the Java tools to do the transformation.
So, my questions:
1) Do I need to wrap the PDF into a WOComponent? If so, can someone
point
me at an example?
2) I'd rather return a streamed PDF. Yes, I'll write a temp file, but I
don't want it to persist. I can't seem to find out how to do that,
either.
