The count property of the Repeater item is supposed to hold the number of items in the Repeater, but that is not true while the items are being created/deleted.

Example:

• set model = 3
• all items will be deleted, starting at index 0
• count is set to 0
• count is set to 3
• items will be created, starting at index 0

Count tends to be too high during item creation/deletion. If a user tries to iterate through the items, based on a change in the count property the itemAt method will always return null for several items.

I would expect it to behave like this:

• set model = 3
• count is set to 0
• items will be deleted
• items will be created
• count is set to 3
