Introduction

We have already covered the existing structural issues in another DOCUMENT, This document gives the details of Reasons for each issue

1. QuestionSet

1.1 Redundant Properties inside questionSet

data 
org.ekstep.question

The org.ekstep.question is generated by data property inside toECML function of questionSet editor plugin.js, Before returning result inside toECML the data property should be made as empty string as the questionSet only requires config data in the renderer side.

1.2 Katex Library being added to ECML alway

The katex library a renderer dependency of org.ekstep.questionunit library and questionunit is a dependency of all the questionunit plugins ( org.ekstep.questionunit.[mtf, ftb, sequence, reorder, sequence] ), Hence it is always added into the ECML of questionSet.

2. v2 Questions

2.1 Redundant media property

The below screenshot shows the code of org.ekstep.question/editor/question-ctrl.js to understand the code that produced the structure

2.2 New properties getting added after edit and save of question

The Four new properties which is getting added into metadata Assessment Item are
conceptData
topicData
data
questionTitle

Explanation for conceptData and topicData

The below code exists inside $scope.formIsValid function which resides in org.ekstep.question-1.0/editor/question-ctrl.js.

if ($scope.questionMetaData.concepts) {
	$scope.questionMetaData.conceptData = "(" + $scope.questionData.concepts.length + ") concepts selected";
}
if ($scope.questionMetaData.topic) {
	$scope.questionMetaData.topicData = "(" + $scope.questionData.topic.length + ") topics selected";
}

As you can if there is already a concepts or topic exists inside the metadata of the question, It adds conceptData and topicData properties, Hence it adds only while edit and save not while creation.

Explanation for questionTitle

The below code exists inside file org.ekstep.question-1.0/editor/question-ctrl.js, function $scope.showQuestionForm

$scope.questionData.questionTitle = questionData.title;

$scope.showQuestionForm only invoked when questionData Object contains values inside it, Upon creating question the questionData is empty, Hence questionTitle property never get's added to $scope.quesitonData

 if (!ecEditor._.isEmpty(questionData)) {
                $scope.showQuestionForm(questionData);

Explanation for data

Refer 2.3 For the details

2.3 Recursive Structure of Question

The Below Screenshot exists inside $scope.saveMetaData function of file org.ekstep.question-1.0/editor/question-ctrl.js

Why the data property only getting added while edit and save, The below code is inside $scope.showQuestionForm function of file org.ekstep.question-1.0/editor/question-ctrl.js,
We have already know $scope.showQuestionForm only will be invoked during edit ( Refer Explanation for questionTitle Issue description )

var questionData1 = typeof questionData.body == "string" ? JSON.parse(questionData.body) : questionData.body;
$scope.questionData = questionData1;

2.4 For MCQ and FTB questions ( Assessment ) the plugin media is getting added inside v2 questions media

This requires discussion, Currently this is the behavior,

2.5 For MCQ the default media is getting added multiple times

The below screenshot is inside $scope.formValidation function of /org.ekstep.questionunit.mcq-1.1/editor/controllers/mcq-controller.js

Refactorization: Reason for Issues QuestionSet and question structure
