Cannot find function asFileUploadItem in object Item. (line 57, file "Code")

[pmpinto]

Line 57 is:

  var typedItem = item[itemTypeConstructorName]();

And itemTypeConstructorName for this specific item is "asFileUploadItem".

I do have a file field on this form.
Am I missing something?

This script builds a method from the item's type adding as as a prefix and Item as a suffix as seen below:

var itemTypeConstructorName = snakeCaseToCamelCase("AS_" + item.getType().toString() + "_ITEM"); 

The problem is that item has no asFileUploadItem() method (see the form API reference for item). This seems to be a long known issue with no fix in sight.
