Do the .hhc and .hhk files have the exact same file name as the project? If you've been messing around with these files (inlcuding the XPJ) it could be that they are out of sync.
The first advice you probably already learned from the School of Hard Knox. Don't monkey with files behind RoboHelp's back!
But we do need to make a clarification. Your post is titled as having an issue with the Index. But you talk in the body about the TOC. Is it the Index or the TOC? Or both?
Yes I know it's playing with fire messing with files behind RHs' back. But I have no choice at the moment. I learnt that using fielneames/project names with hyphens, underscores and blanks in them is supposed to be the cause of making MS HTML Help fail.
So I build some sed/grep scripts changing all filenames and filenames in the apj, xpj, hhc,hhk and what not files. It worked on most of the projects, but at the moment I'm stuck with one where the TOC is empty, and it's indeed the TOC window. sorry, I mixed this up in the title.
RoboColum(n): Yes, the names match.
Could a moderator perhaps change the title from Index to TOC?
P.S. Got it working again:
False alarm. It's still not working.
Last Info: I got it working by copying back configuration files one after another into the project from a backup
and it works now. Don't know what the actual culprit was but would be fruitless to investigate it further since
I have other burning problems.
