[Dspace-general] Customisable Submission Process

[Dalal, Dhaval]

Hi all
I had posted this on dspace-tech but did not receive any suggestions , so sorry for reposting..
I wanted to make a minor change in the last step of the  submission workflow.
Esentially, after the user fills out the metadata about his item and comes to the last page "complete.jsp"- over here there is a link titled "Go to My DSpace"which takes you back to your Dspace Submission Page. What I want here is to branch to another link(webpage) for only one particular collection only while for other collections i want to follow the same link ("Go to My DSpace"). 
I added the follwoing code 

<%

   // this is the submission information
    SubmissionInfo si = (SubmissionInfo) request.getAttribute("submission.info");

    //this is the collection you are submitting to (at least I believe this is the case).
    Collection collection = si.submission.getCollection();
%>

But it shows me a null pointer error for collection..
Strangely collection object is not being passed to the
last step of the submisson workflow.  
is it possible to skip the step only for one particular collection while for other collections continue as normal.

like in show-license.jsp , i get the collection name and if it matches then branch off to that url(submission_complete) else continue..

i am using dspace 1.2.2.
i saw that DSpace 1.3 beta 1 has a customisable submission process?
What does that mean. can i change the upload process?
Does all this make sense..
waiting for a quick reply.
Thanks
Dhaval
