Were these files actually modified in your working tree, or were they 
just at the current tip revision ?

Note that "bzr revert" only changes the contents of the working tree to 
revision -2, it doesn't change the branch history in any way.

You can recover the other files by simply going back to the branch tip, 
by using "bzr revert 
GraphUtils/src/pl/gliwice/iitis/graphutils/view/AbstractView.java".

Or you can print their contents to standard out by running something 
like "bzr cat -r -1 
GraphUtils/src/pl/gliwice/iitis/graphutils/view/AbstractView.java".
