String vpMachine = pageContext.getParameter("viewMachine");
String vpSetNumber = pageContext.getParameter("viewSetNumber");
String vpRevision = pageContext.getParameter("viewRevision");

Answer 1

ok here is an example :
on my custom page, there are few fields based on which user can search model info . search displays all the documents(or should say the data available on that model) from custom table - ex-
1. document name = Proc2009 , revision =1 , model = A1 , viewicon
2. document name = Proc2009 , revision =2 , model = A1 , viewicon
3. document name = Proc2009 , revision =1 , model = A2 , viewicon
if user picked viewicon for either row1 or row2 (that is data for model A1) : fields to be rendered on the oaf page are say:
width , make, engine, setup_info.
But if user picks row 3 - Model A2, fields to be displayed on the webpage are -
width,make, X-axis,Y-Axis, Provision_info, setup_info
I did not use PPR to hide the fields based on the model but set the property of the attribute setRendered(true or false) in process request. reason being its a very complex matrix, and there are many variants. All this works fine. When I add printable page button, it shows up correctly, but hides some fields that should be there for Model A1 and shows some field for Model A2.
I need get the printable page only for this set(Proc2009, rev=1, model=A1).
did i explain it better this time ?
How can I do it ?
thanks
