JSONDataModel does not take care of insertIndex

[tof]

There is a bug in JSONDataModel, the "loadData" function does not take care of insertIndex.
The code is pretty much the same as XMLDataModel, so I copied it from one to another, and it does work:



if(keepExisting !== true){
this.removeAll();
}
this.addRows(rowData);
if(typeof callback == 'function'){
callback(this, true);
}
this.fireLoadEvent();


Replaced by :



if(keepExisting !== true){
YAHOO.ext.grid.JSONDataModel.superclass.removeAll.call(this);
}
if(typeof insertIndex != 'number'){
insertIndex = this.getRowCount();
}
YAHOO.ext.grid.JSONDataModel.superclass.insertRows.call(this, insertIndex, rowData);
if(typeof callback == 'function'){
callback(this, true);
}
this.fireLoadEvent();


And add a fourth argument "insertedIndex" for loadData in JSONDataModel.

Note:
My goal was to reload a row, like this :
dm.reloadId(id, url);

So I :
get the index : idx = grid.getRowById(id).roxIndex
remove the row : dm.removeRow(idx)
insert the row : dm.load(url, null, null, idx)

Could this be native in LoadableDataModel ?
