Bug in TreeGrid when reordering records inside the same folder

[opty]

Hello,

In the sample below, when you try to move item_1 below item_3, it gets instead positioned between item_2 and item_3.
Please note that this only happens when moving inside the same folder

    isc.VLayout.create
    ({
        width:'100%',
        height:'100%',
        autoDraw:true,
        defaultLayoutAlign:'center',
        overflow:'auto',
        members:
        [
			isc.TreeGrid.create
			({
				ID:'mytree',
				alternateRecordStyles:true,
				dataSource:isc.DataSource.create
				({
					ID:'supplyItem',
					dataFormat:'json',
					fields:
					[
						{name:"itemId", type:"integer", primaryKey:true},
						{name:"parentId", type:"integer", foreignKey:"supplyItem.itemId", rootValue:0},
						{name:'title', type:'text'}
					],
					clientOnly: true,
					testData:
					[
						{itemId:1001,parentId:0,title:'folder_1'},
						{itemId:1,parentId:1001,title:'item_1'},
						{itemId:2,parentId:1001,title:'item_2'},
						{itemId:3,parentId:1001,title:'item_3'},
					]
				}),
				loadDataOnDemand: false,
				canReorderRecords: true,
				canReparentNodes: true,
				canAcceptDroppedRecords: false,
				canDragRecordsOut: false,
				canEdit:true,
				editByCell:true,
				modalEditing:true,
				showConnectors:true,
				showFullConnectors:true,
				canResizeFields:false,
				canReorderFields:false,
				canGroupBy:false,
				canPickFields:false,
				canFreezeFields:false,
				canSort:false,
				canAutoFitFields:false,
				showHeaderContextMenu:false,
				animateFolders:false,
				fields:
				[
					{name:'title'}
				],
				dragDataAction: "move"
		 	})
		 ]
	});
	mytree.fetchData();

This happens with latest LGPL build (2010-09-20)

Addendum : this problem happens only with an associated dataSource, so replacing it with :

                data: isc.Tree.create({
                    modelType: "parent",
                    nameProperty: "title",
                    idField: "itemId",
                    parentIdField: "parentId",
                    data: [
                        {itemId:1001,parentId:0,title:'folder 1'},
                        {itemId:1,parentId:1001,title:'item 1'},
                        {itemId:2,parentId:1001,title:'item 2'},
                        {itemId:3,parentId:1001,title:'item 3'},
                    ]
                }),

will work OK

The problem has been encountered at least with FireFox and IE (page in quirks mode as recommended)

Hi,

I am using Smart GWT 2.2 with GWT 2.0.3.

I am seeing the same behavior in IE. Has this issue been resolved? or is there a workaround to solve this issue?

Also running the IE page in Quirks mode.

For other people's reference.

As a workaround for this issue. I wrote a if condition to check if the user is attempting to drag event.getNodes() to the end of the tree (event.getIndex()). If so, then use event.cancel() to prevent the nodes from moving at all.

I hope this helps.
