Thanks alot Marxian. It is now working for me. Sorry for late reply as i was not around for sometime. I have one new problem :P

when i click the feed item, it opens my application GUI but the particular feed data is not loaded. Its gets loaded only when i click the button that is meant to do the data loading task. However in Component.onCompleted() i am using the same data loading method as in button.

1) how can load GUI when dbus method com.myapplication.example() is called ? i know one way is to define DBus service but it is giving me the above mentioned problem.
