Bug or question

What is the current behavior?

I'm getting an error when trying to set multiple text item in a custom question's onLoaded event.

What is the expected behavior?

I think it should work, but am not sure.

How would you reproduce the current behavior (if this is a bug)?

See test code or plunkr below, if you open developer tools you'll see this stack trace:

@SamMousa Here is the working example.

   onCreated(question) {
      // This is sample code, I know I could put this static array in the config above, but my goal is to load it dynamically.
      // 
      const items = [
        {
          name: 'en-US',
          title: 'English',
        },
        {
          name: 'fr-FR',
          title: 'French',
        },
        {
          name: 'ar-AR',
          title: 'Arabic',
        },
      ];
      const multipleQuestion = question.contentQuestion;
      items.forEach(item => {
        multipleQuestion.addItem(item.name, item.title);
      });
    }

Does that mean docs are wrong?

[andrewtelnov]

@SamMousa The documentation is correct. You can store items in JSON. However, you have to assign the list of MultipleTextItemModel instances. It is similar to survey pages. It can be store in JSON and you can assign the list if pages but you can't assign a list of any object into survey.pages property.

Thank you, Andrew
