Here is some example code that can recreate the problem. Run it and on
the last node, drag a row to just below the last row, as if trying to
make it last in the group....you will notice that instead, it takes the
row and converts it to a new node...sort of....

All,
I have an ADG that contains a grouped collection. In the dataset,
there are 21 nodes...each node has 1 to many children. When I attempt
to drag a row, either from another node or within the last node, and
drop it below the last item in the last node(i.e. make it the very
last row in the group and ADG overall), the systems treats it like I'm
trying to drop it at the node level instead of the child level and
throws an out of bounds (which is probably due to my code that
persists the orders in the database).
In watching it in debugger, here are the values that occur.
Here's the setup:
21 groups (nodes) in the adg.
The last group has 4 children (rows).
If I expand only the last node...and drag the first row of that
node to the next to last row, the adg.dropData.index == 3 and the
adg.dropData.parent == the node object that I am in, which is should
because I am dropping it within that grouping. If I drag the first
row of that node to just below the last row, intending on making it
last in the group, the adg.dropData.index == 25 and the
adg.dropData.parent == null.
It obvious that the adg doesn't realize that I am dropping it
within the last position of the group because it's the final row in
the overall adg. So I tried to outsmart it. I created a handler to
determine if the adg.dropData.index >= (the hierarchical tree length +
the length of the all the open nodes in the tree), using the
assumption that if this is true, then the user is trying to put the
row at the end (keep in mind I am also checking to make sure it's not
a node that is being dragged to reorder). If this is true, then I
manipulate the actual event.dragInitiator._dropData and the
adg.dropData values and force the index (which I calculate from the
number of children in the last node) and parent information into them.
To a point, this works and my drop is persisted to my database per
design. However, the dropped row disappears from the grid, only
appearing in its correct position on refreshing the grid.
The problem appears in the AdvancedDataGrid.as class.....within
the updateDropData function where calculations are being done to
re-place the row...because the index value is 25, the top and bottom
parent calculations seem to get all jacked up and in the end, the
_dropData gets reset to the old values, completely overriding my
efforts to cheat.
Has anyone else ever seen this...know of a way to get around it.
It certainly seems like an Adobe bug to me.
Best,
Adrian
