Synopsis: Internal Error invoking autocompletion
Description
I was entering a line of code into a class. I then hit F1, which is my shortcut for autocompletion. A dialog popped up saying that there was an unexpected error and that it was going to back up my changes. I hit OK, and the Internal Error below appeared. I hit Quit. I restarted EiffelStudio and reopened the project. I opened the class that I had been working on. A sequence of dialogs appeared asking if I wanted to restore my class, to which I replied OK. An error then appeared, saying that my class's file did not exist. Looking at the directory in Windows Explorer, the class's file had been deleted! The swap file was not there either!

Problem Report Interactions
This has been fixed in rev#69049. Thanks for reporting.
This has just happened again, when I was re-entering the code that EiffelStudio had just trashed. This time I made sure that the system had been successfully compiled before attempting the autocompletion. It happened at exactly the same place. I had entered this: my_cancel_button.select_actions. I had used autocompletion to enter both parts of this. After the dot, I hit F1. Again the "unexpected error occurred". This time I made a manual backup. When I restarted EiffelStudio and opened the class, it again asked me if I wanted to use the backup. I varied my responses this time, because there are a couple of stupid questions in there about the file having been modified in another editor. I avoided trashing the class this time. The above half-complete line of code was there, so I hit F1 again, and the same error occurred. Obviously I'd better avoid autocompletion in this release!
