Problem with alternating different numbering and listing styles

Hi all, I’m using this great software since openoffice times, and as usual
there more I use it there more I find new ways in doing things.

My last attemp was to build an written exam, since i lecture at an university.
This template is composed of an heading, small title, date and numbered
questions and non-numbered answers alternating (see bellow). The fun part comes
now, in order not to have two arquives one only with questions and another with
questions and answers I build to different styles containing two different ways
of listing, one format for questions and another for answers, so that every
time I hit return the new format is inserted and questions are continiously
numberend in spite of intercalating answers, see example bellow.

  1. xxxxxxxxxx (question 1) “RETURN”

R.: ccccccccc (answer to question 1 - after the previous RETURN the letter
“R.:” are added automatically) “RETURN”

  1. xxxxxxxxxx (question 2 - after previous RETURN an question paragraph style
    is inserted again and numbering is added by one) “RETURN”

R.: cccccccc (answer to question 2 - as with the previous one) “RETURN”

Up to here everything went fine. The reason why doing it this way, is because I
can hide the “answer style paragraph” by modifying simply the character
codition to hidden. This would allow me to hide all paragraphs containing
answers while printing the questions.

The problem is while writting the exam. After I started inserting
questions and answers if I deleted manually (with backspace or del) the last
inserted answer or question and wanted to continue all my subsequent question
number will be numbered taking into account the answer paragraph styles. After
hitting return for an answer it inserts an R.: but after hitting return again
it numbers the next question taking into account the answer paragraph,
generating an non-continuous number list for questions. The only way I can
correct this is creating an new archive and copying and pasting each
paragraph with no formatting.

My question is how can the question style format keep numbering as previouslly
after deleting one of the automatically formated paragraphs? Might this be an
bug, in the sense that while deleting the text it deletes some hidden format
command as well and so both paragraph styles are afterwards not being recognized as
differente anymore?

Hope someone with more in deep LO knowledge could hepl me out here.

I can see from the provided example why the question paragraph style uses an ordered list identifier. It is not clear why the answer paragraph style needs to use an ordered list identifier. It would seem more logical to use an unordered list identifier (bullet / symbol, which could be any Unicode character, such as “R”). This will prevent interference with the sequencing of the ordered list entries.
