Hello,

I can't save my main file anymore. Shortcut and save buttons do not have effects. If I close the file and click "Yes" to the prompt I'm given it does not save either (every modification is lost).
This happened from the moment I "removed" files in the project by removing the #source lines in the main file.
By the way, how do I remove files from my project ? How do I rename them ?

Thanks.

I have a fix out (http://codereview.chromium.org/8974026/) for the SWT exception in this issue. This is unrelated to the main problem of not being able to save files.

[bwilkerson]

I was able to reproduce the problem in one instance, but now I am unable to reproduce it even when I repeat the steps. The original steps that reproduced the problem was to create a new 'hello' application, add a new file, delete the #source line for the new file and attempt to save the file. There were, unfortunately, no exceptions or other output in either the console or the log file.

This does not seem to be happening anymore.
Please reopen if it does.
