Web Dynpro view data to PDF creation issue

Question

Hi ,
I am passing data from Web Dynpro iView to genrated PDF using url link, pdf generation is done using iText java class. 
outputPDFData is the method to which i need to pass the data to but this is where i failed.
Can someone please identify error or suggest how i move from here?
Till now we completed storing test data in a temporary location using ByteArrayOutputStream but to show the data on screen??????
ByteArrayOutputStream os = new ByteArrayOutputStream);
       List data = new ArrayList();
       data.add("Test Data1");
       data.add("Test Data2");
       data.add("Test Data3");
       PDFTestTemplate PDFTest = new PDFTestTemplate();
       PDFTest._outputPDFData_(os,data);
       final IWDCachedWebResource resource = WDWebResource.getWebResource(os.toByteArray().toString().getBytes("UTF-8"), WDWebResourceType.PDF);
       wdContext.currentContextElement().setPdfURL(resource.getURL());
       os.close();
P.S.
I have also referred to this blog by Prakash Singh but wasnt very helpful in my case.

Martin is right,
Any data context node on the next view should also be mapped to the component controller, so when you are changing views you just have to use your material number to invoke the method of the component controller that gets your detailed data, its as easy as this:
before you fire you plug you can use the following:
wd_comp_controller->get_material_details( matnr = lv_matnr ).
Inside your component controller you should have a method called "get_material_details" and an importing parameter called matnr.
once the logic is run to get the details, bind your data to the component controllers Material details context node, this node should also be mapped to the view of the second screen.
So now when the second view opens the data will magically be there
Good luck,
