Hi all.
Anyone working with tree views will immediately encounter an oddity, where the
hilitedElement returns a comma delimited list of the array keys to the clicked
item in the tree view. A comma delimited list of keys is almost completely
useless if you want to get the value of the actual item clicked on! If the item
is an array, it will return that of course.
So I wrote a little function for getting the "actual" value of the key in the
array corresponding to the selected item. There may be another way to do this
baked into the XML library, but I could not discern it.

on hiliteChanged
-- this goes into your tree widget script
local tElement
put the arrayData of me into aTreeData
put the hilitedElement of the target into tElement
put getArrayKeyValueFromKeyList(aTreeData, tElement) into tKeyValue -- now
you have the value
pass hiliteChanged
end hiliteChanged
function getArrayKeyValueFromKeyList aArray, pKeyList
-- this can go anywhere in the message path
repeat for each item tKey in pKeyList
put "[" & quote & tKey & quote & "] " after tArrayKey
end repeat
put "aArray" && tArrayKey into tArrayElement
return value(tArrayElement)
end getArrayKeyValueFromKeyList
