[TxMt] AppleScript window object broken?

[Alan Watson]

The AppleScript window object in TextMate 1.5.8 (under Mac OS 10.5.6)  
seems to be broken. I get get the window name and bounds, but not the  
window document:

   tell application "TextMate" to return (document of front window)
   => NOTHING

Compare this to TextEdit, which has a similar dictionary:

   tell application "TextEdit" to return (document of front window)
   => document "foo.txt" of application "TextEdit"

Am I doing something wrong?

Regards,

Alan
