This is a timing problem and sort of a FAQ. So, please search the list 
for an in depth explanation. In short, pipeline setup happen *before* 
pipeline execution IOW when you pass the parameter to the setup method 
of your transformer, the generator (the XSP) hasn't been executed and 
thus the parameter is not set, yet.

This would not work as -- again -- the action is run before the XSP is 
selected. You may write an XSP-action (or Java action) for this or a 
custom input module. Maybe you can achieve the desired effect by 
combining several modules...

You may want to consider flow.
