Was this issue resolved. Am also facing the same problem.
It seems there's no resolution, as I've just tried it with RoboHelp 11. Downgrading DITA-OT to version 1.5 is impossible because it won't be able to process our DITA files written for 1.8.4, not to mention having to redo all the plugins and all the specialisations, it's just not doable. This means effectively that RoboHelp is unable to import DITA files, period.
Can we have a comment on this from someone from RoboHelp, please?
You seem to have the mistaken impression that the Adobe folks are the only folks hanging out here. Sure, they do visit from time to time, but this is primarily a user to user forum. If you have something pressing that needs an "official" answer by Adobe, you need to contact support. Either that or consider filing a wishform/bug report.
Thank you, Rick, I'll do that. I've seen so many replies by someone from Adobe that figured they were reading these messages. Well, I suppose they are, so that's good. :-)
