Applescript create contact sheet Error

Question

Hi all,
I'm using Applescript to filter my images and create a contact sheet from those filtered images. Now I'm stuck at creating the contact sheet. The error I get is:
error "Can’t get list of {alias \"Macintosh HD:Users:stopar:Desktop:sorted:OA0001-1.jpg\", alias \"Macintosh HD:Users:stopar:Desktop:sorted:OA0002-1.jpg\"....
My script looks like this:
tell application "Finder"
set sourceFolder to choose folder  -- temporary testing by selecting a folder. File filter script will be placed here
set filesList to (files of entire contents of sourceFolder) as alias list
end tell
tell application "Adobe Photoshop CS4"
activate
create contact sheet from files list of filesList
end tell

Answer 1

It looks at first glance that you are asking for a list twice… This worked for me… Just tested with a bunch of TIFFs. Put a basic filter in there too.
tell application "Finder"
set sourceFolder to choose folder
set filesList to (files of entire contents of sourceFolder whose file type is "TIFF") as alias list
end tell
tell application "Adobe Photoshop CS2"
activate
create contact sheet from files filesList
end tell
and as if by magik Im back to the other me… again…
