I have a view impl say SampleView.java.I have a table in my view.When a row is clicked, a new place is passed to the place controller like,

```
placeController.goto(new ScreenPlace()) ;

```

Now the issue is, i need to pass some data from SampleView to ScreenPlace , so that i can use that data in the ScreenView.Data is basically a MAP of key value pair which i need to pass from SampleView to ScreenView via ScreenPlace.Or in other words, how can i transfer data from one view to another view.How can i do this?.I'm a newbie to GWT.Please help!.
