Calendar - Cannot Add Events or Parts

description

I am getting an IndexOutOfRangeException when I try to add an Event or a Part to a Calendar that I have created. I am using MVC. I'd love to be able to get this to work because my users would like to have multiple calendars for different sections of the site. Stack trace at the bottom of this post.

STR:
1. Download latest version from GitHub (as of Friday, 27 Jan, 2012)
2. Add Calendar type to MVC project
3. Add an Event or drag a Part onto a child zone of the Calendar (site-wide zones work)
4. Fill in values and Publish
5. This error shows up:

Server Error in '/' Application.

Index was outside the bounds of the array.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.IndexOutOfRangeException: Index was outside the bounds of the array.

I did a quick test and this seems to have solved the problem. You can close this issue. I'll re-open it if the error occurs again.

Thanks!

I never managed to reproduce this but I have a theory. Could you try this commit and tell if it makes any difference?

I debugged the project and stopped the application as it enters N2.Definitions.SortChildrenAttribute.ReorderBy():

private IEnumerable<ContentItem> ReorderBy(ContentItem item, string sortExpression)
{
ItemList temp = new ItemList(item.Children);
temp.Sort(sortExpression);

item.Children.Clear();
foreach (var child in temp)
item.Children.Add(child);

return Utility.UpdateSortOrder(temp);
}

I can get the parts to add by hovering over the 'item' parameter before 'ItemList temp = new ItemList(item.Children);' is executed. Maybe the debugger is forcing a value to come back instead of the result of item.Children being null. After it adds one time, I can then add children at will with no errors.

Hopefully this helps in tracking down what the issue is.
