So basically I have an array of objects with properties. Now the array is 102 elements long from a particular dataset that I am testing with. #'s 4 and 6 in the array come through fine but 5 has an issue. I have checked this site and many others and I've found one instance of the exact issue, their solution to use property notation did not work.

When I check questionList[5]['id'] it returns "undefined", same with questionList[5].id. I don't understand why. Here is the object that is the problem:

questionList[5]: Object
    id: "questionPage-6"
    attached: ""
    options: Array[4]
    required: true
    text: "How often do all of your active members meet?"
    type: "dropdown"
    value: ""

Whereas this question right after it:

questionList[6]: Object
    attached: ""
    id: "questionPage-7"
    required: true
    text: "How are these meeting successful and how could they be improved?"
    type: " textarea"
    value: ""

When I do questionList[6]['id'] I get "questionPage-7".

Because 5's id is undefined I can't create the tabs in jQuery UI that I'm trying to create, I get bad fragment identifiers because the div id that uses the id is set as #undefined.

PS - ALL the other elements work just fine. 5 for some reason is broken. –  Colin Knapp Jan 26 '12 at 4:36
    
Could you put together a jsfiddle showing the error? –  Jake Jan 26 '12 at 4:39
    
Can you please show the code that creates this array of objects? What you show above is not JS - is that what shows in the browser console or something? –  nnnnnn Jan 26 '12 at 4:39
    
How is the array being initialized? Do you have raw JSON for it? How was the object value above printed? –  Russell Zahniser Jan 26 '12 at 4:40
    
This is coming from a json string, not being generated. check out the JSON array –  Colin Knapp Jan 26 '12 at 4:52

The problem is that your raw JSON has the id property of the element at index 5 with a space, that is it has " id" instead of "id".

Demo showing it works if you use questionList[5][" id"]: http://jsfiddle.net/VYwYC/

(Obviously you need to fix the source of the JSON.)
