Mac Mountain Lion, SE Beta 7. Sequence:
1. Created new file in finder (command-d, rename result to ftpupload.html).
2. In open tool window, fn-f5 to refresh and see file.
3. Right-click file, add to project. Bang!
Slick-C Error
Variable element or variable not initialized
file=backtag.ex offset=360
The stack indicates it was trying to add to the tags file.
Edit: I then opened the file, and from its tab in the tab group, tried to add file to project. It says it's already part of the project. I probably want to retag the workspace at this point, but plan to first upgrade to Beta 8.
