Path issue

Question

--I've been looking at this for some time, without a successful solution:
--Scenario 1 >> I have two TextEdit files on two different volumes. They have different names. They have been opened and appear on the desktop. I am seeking the path for each.
--Using this script:
set App_ to application "TextEdit"
set DOCS_ to documents of App_ --(yields a variety of info for each item, including the correct name and path for each)
set Doc_Name1 to name of item 1 of DOCS_ --(extracts correct name with no issue)
set Doc_Name2 to name of item 2 of DOCS_ --(extracts correct name with no issue)
tell application "System Events" --(necessary, and apparently works with any valid application name inserted)
set Doc_Path1 to path of item 1 of DOCS_ --(extracts correct path with no issue)
set Doc_Path2 to path of item 2 of DOCS_ --(extracts correct path with no issue)
end tell
*--Question 1:* What is the tell block accomplishing, considering that any application seems to work? Without it I get "TextEdit got an error: Can't make path of document 1 into type reference."
--*_Here's the issue for which I haven't found a workaround:*_
--Scenario 2 >> Exactly the same as Scenario 1, except that the two files have the +SAME NAME+. When the above script is used, the path for both items is set to the path of the last file opened, even though the path given in DOCS_ for each item is different (and correct).
*--Question 2:* Is there a way to extract the correct path information when the file names are identical. It would seem that using a window id approach might be the answer, but window id doesn't yield path information so far as I can tell.

Answer 1

I'll do my best to keep this response understandable.
1) Hiroto posted three codes, and I tried each using "TextEdit" and with two same-named TextEdit windows opened from two different volumes. The results:
CODE – 1
(using terms from application “System Events" retained in the script)
With AS Editor: works as expected
With Script Debugger: works as expected
(using terms from application “System Events" removed from script)
With AS Editor: works as expected
With Script Debugger: error: “TextEdit got an error: Can't make path of document 1 into type reference.”
CODE – 2
(no “using terms from” in original code)
With AS Editor: works as expected
With Script Debugger: “type reference error” at “set Doc_Path1 to” (Hiroto anticipated this, but thought it might not happen in current Script Editor – it didn’t, but evidently Script Debugger can’t handle it at this time).
CODE – 3
(no using terms from in original code)
Works as expected with both editors.
Using "Preview" in place of TextEdit with same-named Preview windows opened from two to four locations, CODE -1 fails to distinguish the paths properly and the other two throw errors. More on this later, as I'm pretty sure I've worked out a solution.
2) These results seem to confirm the response from dev_ sleidy (using TextEdit). Clearly, the fact that I was using Script Debugger necessitated the 'using terms from . . .' or 'tell app "System Events"', and was responsible for our different results. dev_ sleidy also appears to have been absolutely correct that (with TextEdit) the proper paths were given for same-named items from different locations. I must have mis-read some result earlier, and I apologize for the confusion.
3) _With regard to the "Preview" issue and same-named windows from different locations_, I said earlier that the script was returning the same path for each of the open windows -- the path of the last one opened. That is correct, but a better way of characterizing it is that it's the path of the frontmost window.
I added instructions to the code to sequentially bring each window to the front, getting path information for that window when it is frontmost -- and that seems to solve the issue completely (it also does not cause any problems with TextEdit, which previously worked properly without the extra code). I'll post the new code if anyone is interested.
3) Other applications: the code I now have appears to work well with TextEdit and Preview, but I'd like to make it as universal as possible. I've played around with Safari web archives, and other native apps, and they all seem to have their own peculiarities. I've also looked at MS Office apps; "Word" appears reasonably straightforward, but I haven't found my way with Excel and PowerPoint, mostly because of the different types of windows that may be open (I also expect that different MS versions might require different solutions). And I realize that there are apps (even native ones) for which I probably can't get the path, or at least easily.
I'm not asking for any response to this post (but I certainly wouldn't object); I'll just plug away on it as I have time. Thanks for the previous responses.
