How would the dragDrop handler know the value of tLine?
Also, it seems like 'me' has two different meanings in the dragDrop
handler.
Try this for adding lines to fields that may be empty or need a
return, etc:
put cr & line 1 of tDraggedArray & cr after me
filter me without empty
You also might consider with the syntax
if tParameter is among the lines of the dragDestination then
Hope this helps,

Hi folks,
To help with some XML file analysis, I've created a pair of list
fields that display the current node's children. The 'left' field is
filled with all the child nodes and I filter this list down to just
the nodes I will investigate further, by dragging into the 'right'
list the nodes I will ignore.
I thought I'd use this opportunity to learn about drag & drop, so
the script below sits in each field and allows me to move fields
back and forth between 'monitor' and 'ignore' lists - well, nearly!
It's working but in an overall 'copy' mode - not 'move'.
My problem is with the 'line -3' which should check that the drop
was successful and then delete the line from the source field.
Any clues as to what I'm doing wrong?
/*
Drag and drop control for managing parameters between 'Monitor' and
'Ignore' lists
*/
on dragStart
---Start dragging a Parameter
put the hilitedLine of me into tLine --a line number reference and
not the text
put the line tLine of me into tParameter --gets the text from the
referenced line number
set the allowableDragActions to "move"
set the dragAction to "move"
set the dragData["text"] to tParameter --creates the 'payload' for
the drag & drop action
pass dragStart
end dragStart
on dragEnter
--Enable as a receiving field
set the dragAction to "copy"
pass dragEnter
end dragEnter
on dragDrop
--Put some dragsource logic in here - exit if dragSource is not
the expected field or the dragData payload is empty
--Deposit the drag 'payload'
put the dragData["text"] into tDraggedArray
if me is not empty then put return after me --adds a return after
the last item when the destination list is not empty
put line 1 of tDraggedArray after me --adds the Parameter to the
list
sort lines of me --sorts a-z
if the dragDestination contains tParameter then delete line tLine
of me
pass dragDrop
end dragDrop
Oh, and a minor point - dragAction is set to 'move' but I get the
OSX 'plus' icon attached to the drag action, which implies copy?!?
