After updating my Help ID file, I opened Robohelp and noticed
that most of the mappings were lost.
I had just copied the new help ID file to the location of
existing one. The new help ID file was the same as the existing
one, with a few new help IDs. I have used this procedure many times
in the past without problems.
Is it possible to retrieve my old mappings? I do have daily
tape backups that I can go back to. I am hoping there is some file
I can retrieve, as I do not want to completely go back to on old
version of my project.
You seem to have answered your own question. Just retrieve
your most recent working version of the help ID file. You might
need both the .ali and .hh (or .h) files. All you have to do is to
bring these into your project folder and compile and the old
mappings will be restored without losing any other editing.
However, I wouldn't do it this way. I'd try to figure out why the
new file failed to work and see if I could fix it. You can open it
in Notepad as it is just a text file.
