[FLOW] How to access flow parms in the site map?

[Yatin Shah <no...@kripa.com>]

1. How does one access the flowscript objects from a site map? In my 
pipeline I use a selector to check my request parameter and branch to 
appropriate logic for serializing into certain formats. ie. normal 
pages(with navigations), pop-ups(w/o navigations), pdfs and printer 
version I want to replace the request parameter usage with a flow 
parameter. Is it possible? What is the usage format?
2. Now, here is why I need it ...
    If I have multiple pipelines initiated as a result of a single user 
URL request(ie. Wizard style forms) as in:
URL: /A/B/Action-1?VER=POP --> Pipelines:Form1, Form2 and Form-Finished
I've noticed that the request queryString from the original URL request 
is not available to the pipeline processing the form 'Form-Finished'(the 
Form2's continuation became the URL for the Form-Finished pipeline). So 
the solution I resorted to was to extract the queryString in my flow and 
allow it to be accessed from the site map.
   
TIA
