***UPDATE - PROBLEM RESOLVED***

This is a strange one!

For this example, I have 2 features. I put a counter to get 0 and 1 for the value. Then I’m updating my JSON with the _count value. The output from the JSONUpdater has SERIALNUM = 1 for both features. If I change the sort, it will set both to 0. I’m passing in the same feature in the Document and Update input ports. I’m not sure the distinction between the two input ports.
