Can I ask if anybody knows where does the rule to have at least 3 subquestions and answers come from ?
I see nothing in the code that should prevent it from working in more cases.
What if ddmatch only ask for at least 1 subquestion and 2 answers only ?
I ask for this because I am currently trying to upgrade the blackboard_six format to really work with Moodle 2.1
This format currently use the old renderedmatch qtype to import blackboard match questions.
It can't use the core match qtype because Blackboard matching questions can have as few as 1 subquestion (I know that a question with only 1 subquestion and many answers is more a multichoice question than a matching one but this is how Blackboard is working !!) and also Blackboard matching question can have HTML tags both in subquestions and in answers (wich is the case of ddmatch questions so all is good here).
So if ddmatch could support questions with number of subquestions > 0 and number of answers > 1, I could simply import Blackbord matching question as Dragdrop matching ones and would have no work to do to try to upgrade rendered match to Moodle 2.1
