I'm trying to define a questionnairereponse the effectively has a number of distinct sections (or groups I guess).

I'm trying to achieve this by attempting to slice the inner group element, within the group section of the definition. It seems the Forge tool does not like this - it creates a new element, but not sub-elements (linkid, text, title etc). Am I approaching this incorrectly? If I edit the XML (adding a nested group element) by hand and load it into Forge, it sees the group as a slice and displays it with all the elements.

Has anyone achieved something similar - if so, can they steer me in the right direction:

To demonstrate:
...
QuestionnaireResponse

root

- group element - sliced

       -  Section 1 (sub-group)  - slice
             - question 1.1
             - answer 1.1

       - Section 2 (sub-group)  - slice
             - question 2.1
             - answer 2.1

...
etc

Thanks
Duncan

Hi Duncan, thank you for reporting this issue! I think I can reproduce it in the current Forge 14.4.1 release. If I slice QuestionnaireResponse.group.question and add a slice, then Forge does not generate child elements (linkId, text, answer) for the slice. Same issue if I try to slice QuestionnaireResponse.group.question.answer. However slicing the identifier element works correctly. I'll investigate the issue.

Thanks!

Also, you might note that this is probably not what you want to do with QuestionnaireResponse, that is the role of the Questionnaire resource itself. It provides the definition of how a QuestionnaireResponse should be structured, and all the other metadata around its use, such as prompts for users, valuesset bindgings, enabling-when conditions, data types etc.

Servers that support validating QuestionnaireResponses validate them against the Questionnaire they were created against.

Hi @Brian Postlethwaite

Thanks for this - so to get my head straight - do I create the grouped structure in the Questionnaire and then reference the questions in the questionnaireresponse?

Could you point me to an example of this that I can refer to?

Thanks
Duncan

Brian Postlethwaite (Dec 15 2016 at 08:50):

Just create the instance of a Questionnaire with the structure that you desire, then create a matching QuestionnaireResponse (using the linkId to match the items in the Questionnaire to the Response), and populate the Q reference in the QR.

Thanks again @Brian Postlethwaite . Out of interest, are the structuredefinitions for these examples available?

@Michel Rutten , note that Forge seems to have the same issues with Questionnaire , as it does QuestionnaireResponse.

Cheers
Duncan

Brian Postlethwaite (Dec 15 2016 at 10:15):

There are no structure definitions required for Questionnaires or questionnaire responses to do what I described, that's their normal usage.

Brian Postlethwaite (Dec 15 2016 at 10:16):

Questionnaires are typically processed by some form of user interface system to display the controls to a user, then save the QR as its output.
