For anyone else struggling with this, here's how I went wrong:
I named the individual radio buttons on the hierarchy pallete. For reasons unknown to me, they MUST be left as "(untitled radio button)" . I had designated names such as "yes", "no", and some multiple choice answers. RawValues only export for these if they are left with their default unititled names. The exclusion group itself can be renamed of course-that seems to have no effect on the issue.
Just an example of some baffling programming in LiveCycle.
Many thanks for this workaround. I have been searching for a solution for 18 months!! It would be good for Adobe to fix this glitch in the Acrobat X program.
I have also gone one step further and named the exclusion group with codes to identify what the values refer to. (eg. The name of one exclusion group with three options is SSPtype-edbd1-intell2-hosp5) This wouldn't be practical for long lists of options but it helps when it comes time to interpreting the exported data.
I wonder if there are any other field types that have weird problems like this one????
Once again, many thanks for your assistance!!!
