ERROR: No WorkingTree

[Matt Funk]

Hi,

I am trying to put a project under bazaar and i have a question. 
I got all my code and associated folders and did:
- bzr init
- bzr add (all my files/folders)

- i pushed that to a different folder 'foo' which created the .bzr folder in 
it.
- i checkout out the code to a folder in foo and called it trunk.

Not sure if what i did is good or bad policy, but anyway, i removed some of 
the folders in foo/trunk. When i try to do a commit i get:
bzr: ERROR: No WorkingTree exists for "file:///foo/.bzr/checkout/".

I get the same error when i go to foo and do: bzr status.The checkout still 
works though. So i am little confused why i cannot commit and what this error 
means?

(I also checked out the code to a different machine, but i didn't do anything 
there except compile the code)

I'd greatly appreciate if someone could shed some light on the situation.

thanks
matt
