How to close a window programatically.

I have a back to previous screen button in my application and i dont use history.. So i want to programatically trigger the window close button so that this window will be removed and previous will be displayed.

When i tried using this.destroy & this.hide , both closes the window, but i am no longer able to open the window again by double clicking on the listgrid, untill i refresh the screen...


protected void prepareBackToSrchMode() {

this.hide();
}
