I can't see the code of my class.

Hi,

I have a serious Problem, by developing my project,  all was ok.
suddenly by trying to opening a class on my Browser,
I get the following failure and  I can't anymore open this class. All
code that I writte, I can't see, but I can run my Simulation
without problem, so I can nothing do by the code of this class. Please
have someone an idea?.  Thanks very much.

This is the failure:

This was caused when you do something like Smalltalk condenseChanges, what
is not working good.

The sincronization between your code and the sources are gone, but the
objects still live.

Could recover code with some external text editor , like BBEdit (the best on
OS X), and looking for all occurrences of Simulation, or other .

Take some time from you, but eventually you could have the text again and
produce a Simulation.st with BBEdit  and fileIt again.

When you fileIt again (if is the same code) , no more complaints from
Browser for this, but could for other code.

Hope this help

Edgar
