Extra line item added when adding an item in the item sublist

Hi All,

I'm seeing some peculiar behavior when adding an item to an item sublist. You can see in my client script code below, all that i'm doing is calculating a credit card fee and adding a new item (called "Credit Card Fee", w/item id = 14506). All I do to add the new line item is to select a new line in the sublist, populate the item and amount fields and commit the line.


What happens is that it creates the new line, then adds another one below it. It appears to be a timing issue, that while NS goes to retrieve the information for the item, I am commiting the first line. When NS returns the other information, like description and price level, It puts them in a new line item.
