4.6 UI: ArgumentOutOfRangeException: Argument is out of range. Parameter name: index

I am following a tutorial doing a list view and is trying to add an input field to the canvas and get this message. Could someone please help me understand what i do wrong here, can't figure it out myself?

Here is the scene:



I get the error when I click on the input field.

The code i use is:

Code (csharp):

1.  
2. usingUnityEngine;
3. usingSystem.Collections;
4. usingSystem.Collections.Generic;
5. usingUnityEngine.UI;
6.  
7.  
8. public class setupScrollableList_Script : MonoBehaviour {
9.  
10.     public GameObject itemPrefab;
11.     public int itemCount = 10;
12.     public int columnCount = 1;
13.     public Scrollbar theScrollBar;
14.  
15.    void Start () {
16.  
17.    RectTransform rowRectTransform = itemPrefab.GetComponent<RectTransform>();
18.    RectTransform containerRectTransform = gameObject.GetComponent<RectTransform>();
19.  
20.    //calculate the width and height of each child item.
21.    float width = containerRectTransform.rect.width / columnCount;
22.    float ratio = width / rowRectTransform.rect.width;
23.    float height = rowRectTransform.rect.height * ratio;
24.    int rowCount = itemCount / columnCount;
25.    if (itemCount % rowCount > 0)
26.                   rowCount++;
27.  
28.       //adjust the height of the container so that it will just barely fit all its children
29.       float scrollHeight = height * rowCount;
30.       containerRectTransform.offsetMin = newVector2(containerRectTransform.offsetMin.x, -scrollHeight / 2);
31.       containerRectTransform.offsetMax = newVector2(containerRectTransform.offsetMax.x, scrollHeight / 2);
32.  
33.       int j = 0;
34.       for (int i = 0; i < itemCount; i++)
35.        {
36.       //this is used instead of a double for loop because itemCount may not fit perfectly into the rows/columns
37.          if (i % columnCount == 0)
38.          j++;
39.  
40.          //create a new item, name it, and set the parent
41.          GameObject newItem = Instantiate(itemPrefab) asGameObject;
42.          newItem.name = gameObject.name + " item at (" + i + "," + j + ")";
43.           newItem.transform.SetParent(gameObject.transform, false);
44.  
45.          //move and size the new item
46.          RectTransform rectTransform = newItem.GetComponent<RectTransform>();
47.  
48.          float x = -containerRectTransform.rect.width / 2 + width * (i % columnCount);
49.          float y = containerRectTransform.rect.height / 2 - height * j;
50.          rectTransform.offsetMin = newVector2(x, y);
51.  
52.          x = rectTransform.offsetMin.x + width;
53.          y = rectTransform.offsetMin.y + height;
54.          rectTransform.offsetMax = newVector2(x, y);
55.       }
56.  
57.       theScrollBar.value = 1;
58.  
59.     }
60.  
61.  
62. }

 

Can you post the full error message with the line number etc....

 

Thanks for answering. There is no line numbers to my code, this is what i have:

 

I just tested without the code and get the same result??

 

Very strange, i deleted the first inputField and added a new one and now the errors are gone? ...maybe some type of bug.

Problem seems to be solved and thanks for your response.
