yes, it seems you can not drag from scrollable container.
You can try ontouchstart event cut your object from draggsCnt (or create clone) and paste it into Ext.Viewport with floating style and same position, and then ontouchmove event initialize draggable on your cloned object.
Hey guyz i'm facing a prob , is it possible to drag and drop in same container or toolbar for instance. appreciated if answered ,thanx in advanz
for now this thing works in same container only. If you need to drag and drop object from one container to another then you should move this object to target container on before dragging.
This operation may cause unexpected problems, I do not know yet... not tried
I think the better - wait for official API for Dropping behaviour from Sencha.
Or you can modify my one.
