Cappuccino Drag and Drop Error

I'm trying to implement drag and drop in cappuccino but keep getting an error when i drop an image on a CPView, i copied the error message from console below.

CPInvalidArgumentException: - [CPImage removeFromSuperview] unrecognized selector sent to instance 0x0051bd

I'm dragging an image from CPCollectionView which is contained inside a CPScrollView and dropping it on a CPView. I followed the example from the ScrapBook tutorial.

Below is the code on my CPView for dropping, this code causes the output from the console

- (void)performDragOperation:(CPDraggingInfo)aSender
{
    var data = [[aSender draggingPasteboard] dataForType:PhotoDragType];
    [self addSubview:[CPKeyedUnarchiver unarchiveObjectWithData:data]];
}

I defined my drag type in my AppController.j since my CPScrollView is defined their, don't know if this is causing the issue.

Thanks.

What's in the drag and drop pasteboard is NOT the view, it's the representedObject of the collection view item. (In your case a CPImage object).

The solution here is to create a new CPImageView and add it to the drop view, then set the image of that image view to the pasteboard data (assuming it's always an image).
