I have been using the C# question type as provided here: http://coderunner.org.nz/mod/forum/discuss.php?d=79
using the steps to create a question type here: http://coderunner.org.nz/mod/book/view.php?id=193&chapterid=749
However, I am running into the issue where I can save the new question type and have it displayed in the question types dropdown, however, if I go to create a new question with the custom question type I get the error:
"Error loading prototype: Error fetching prototype. qtype_coderunner/Prototype DEMO_C_VIA_PYTHON is unavailable in this context, or does not exist."
The original question I created the question type for, works perfectly, however I can not create any more questions using the question type.
If any more information is required, please ask.
