"Cannot undo. Some files were changed"
I have been getting this error alot lately;
maybe just because of the work I have been doing.
I may be modifying several files at the same
time, and then because I switch to another application,
the files get saved or if I do a compile, the files
will also get saved. Then if I decide to undo the
change in one of the files, I get the message "Cannot undo. Some files were changed."
This isn't how I thought undo worked. Based on earlier
discussions, I thought user edits were classified as either simple (edits made to a file) or complex (edits made to multiple files,e.g. by doing a rename refactoring).
In my case I am just doing simple edits on multiple files.
The edits are not tied to a refactoring, or other action.
I am expecting IDEA to be able to keep undo-ing changes per file unless it encounters a 'complex' action.
Is this a bug?
