Encrypted Disk Images and ApplescriptObjc

Question

Hi all!
Im a bit of an applescript newb but i can find my way around most things. Ive been working on an applescriptobjc project in the new xcode 3.2 in snow leopard and I cant for the life of me get it to mount an encrypted .dmg file.
My script is as follows:
on mountButton_(sender)
set filePath to (POSIX path of (choose file with prompt "Select a file to use" of type {"DMG"}))
tell current application to do shell script ("hdiutil mount \"" & ¬
POSIX path of (filePath as string) & "\"")
end mountButton_
This works for non encrypted files but not encrypted ones. The weird thing is this script works perfectly fine in applescript editor but not in my Xcode compiled project.
Anyone have any ideas?
Cheers

Solved it!! Through sheer serendipity I stumbled across the solution!
Turns out the shell script needed an & on the end. No idea why.
ie.
tell current application to do shell script ("hdiutil mount \"" & ¬
POSIX path of (filePath as string) & "\"&")
Im not all that familiar with shell scripts. Is there anyone who can tell me what I've actually done by including the & on the end? Just for future reference.
Cheers
