Applescript to launch an application and wait till it exits

Question

I have written the applescript to launch an application and wait till it exits and but it is not working. Here is the code for that
tell application "/Applications/Pages.app" to activate
tell application "/Applications/Pages.app"
    repeat until it is not running
    end repeat
end tell
But when I tried to close the app, the script is still running. I think the reason is , even though I closed the window, that process is still running. Can you please help me to solve this problem?

Trying to make this kind of thing work from the script editor is going to give you headaches. A better approach is to create a script application.  Copy the following code into the Script Editor, and then save it as an application with the "Stay open after run handler" checkbox checked. Then run the resulting script application directly.
on run
  tell application "Pages" to activate
  -- add a longish delay to allow the application to start
  delay 5
end run
on idle
  if application "Pages" is not running then
  -- the application has quit, so go to the 'on quit' handler
  quit
  end if
end idle
on quit
  -- do whatever you want to do after the application has quit
  -- allow the app to quit itself
  continue quit
end quit
