Got the answer.. :-)Thanks for the contribution ... Onload the page the repeat control is looking for the session scope value which is null. onclick of the link only sessionScope will be availabe to the page .. by making repeat control visibility hidden while loading the page solved the issue.... :-) — user1802880, Dec 12 '12 at 13:43

You don't catch null values. One possible way:

    var viewName = compositeDate.PDViewName == null ? 'someDefaultName' | compositeDate.PDViewName;
    var theView = database.getView(viewName);

Of course you could also stop the code if viewName is null. You shouldn't use sessionScope here -> your code will break if a user has the unheard idea of opening 2 browser tabs in your application.
