Groups of shapes can be dragged outside the layers and stage in kineticjs

Question

Groups of shapes can be dragged outside the KineticJS layers and stage and are lost. Below tutorial (dragging) works differently in ie9. http://www.html5canvastutorials.com/labs/html5-canvas-drag-and-drop-resize-and-invert-images/

Answer 1

Yes, that's true...shapes can be dragged outside their group.

If you want them contained inside the group, you can set the dragBoundFunc function on the objects:
