[Dojo-interest] DataGrid with dojo.store.JsonRest reverts to old value

OK, so I've been debugging this I found that if I add the two indicated lines
to doApplyCellEdit, then the value does not revert.

I added these lines because I could not see anywhere that the DataGrid's
item data was updated during the "apply" operation.

I doubt this is the best or proper fix, so I would appreciate if anyone from
the dojo team could help me track this down.

	doApplyCellEdit: function(inValue, inRowIndex, inAttrName){
			identity: this._by_idx[inRowIndex].idty,
			onItem: dojo.hitch(this, function(item){
				var oldValue = this.store.getValue(item, inAttrName);
				if(typeof oldValue == 'number'){
					inValue = isNaN(inValue) ? inValue : parseFloat(inValue);
				}else if(typeof oldValue == 'boolean'){
					inValue = inValue == 'true' ? true : inValue == 'false' ? false :
				}else if(oldValue instanceof Date){
					var asDate = new Date(inValue);
					inValue = isNaN(asDate.getTime()) ? inValue : asDate;
				this.store.setValue(item, inAttrName, inValue);

				var data = this.getItem(inRowIndex);
				data[inAttrName] = inValue;

				this.onApplyCellEdit(inValue, inRowIndex, inAttrName);

Also, this code only works with a JsonRest store wrapped directly in an
ObjectStore.  I still have the TypeError problem if I wrap the JsonStore
with a Cache/Memory object before wrapping that in an ObjectStore.
