Import conditions doesn't bring in "Show as per expression" settings

Environment: FrameMaker version 8.0p277 on Windows XP Professional SP2

Hi,
We've just started to use the Boolean expression feature in FrameMaker 8.

With previous versions of Frame, we used to save our Show/Hide settings in various control files or template(for example, an Australia Print file, a UK Online file and so on). Then, during the publishing stage, we'd import conditional text settings from the appropriate control file into the book.

I know this method is still mentioned in the FrameMaker help.

However, from our experiments with Frame 8, it looks like we *cannot* use this method with the Boolean expression feature. If you import conditional text settings from a file, it doesn't seem to bring in the "Show as per Expression" settings.

Is this correct behaviour or are we getting something wrong?

Thanks in advance,
Suchi
