"Accessed None" but with a UI Wrap Box

[BigMartin58]

I am following the tutorial here, but I seem to have run into an unusual error.

When I run the PIE and load the UI, it errors “Accessed None” on a widget wrap box. The wrap box is set in the widget. I tried to use the “Is Valid” macro, but no matter how many times I revalidate it, it fails. I am unable or at least unsure of how to “set” it when it fails.

The variable ‘inventory map’ is of the right type, but has no value assigned to it.

It seems what I was experiencing was simply a bug. It is no longer behaving this way after a restart.
