[FNR] TreeGridDragSource.onDragStart doesn't work correctly with CellSelectionModel

[gald]

on GXT 2.2 and before

if the tree grid selection model is a CellSelectionModel nothing append
because the method treeGrid.getSelectionModel().getSelectedItems() don't return anything

we need to do something like that near line 84



GridSelectionModel<ModelData> sm = treeGrid.getSelectionModel();
List<ModelData> sel;
if (sm instanceof CellSelectionModel<?>)
{
sel = new ArrayList();
sel.add(((CellSelectionModel) sm).getSelectCell().model);
}
else
{
sel = treeGrid.getSelectionModel().getSelectedItems();
}

This is already fixed in SVN. But you should rethink this approach if it makes sense to use CellSelectionModel to drag a hole row.

ok great,
yes for me it make sense because the end-user edit cells and prefer the CellSelectionModel for this
