Description Shenxue Zhou CLA 2012-05-24 16:25:29 EDT 
In GEF based graphical editors, if I drag a node outside the visible area of the editor's canvas, scrollbars will appear after the mouse is released. But the editor won't scroll to reveal the dragged node. User has to scroll the editor manually in order to see the dragged node.

I've tried to call ScrollingGraphicalViewer's reveal() method after the node is dragged. It only works if part of the node is still in the current visible area of the canvas. If the node is moved "far" away, it won't scroll the editor to reveal the node.

Is there a workaround for this issue?
