Blueprint UI issues when switching between array entries

If you are editing the default properties of a complex array, the text often goes into a weird “selected but not focused” state where your typing has no effect, so you ending up clicking the entry 2-3 times to get focus. It appears to be better or worse depending on the type or complexity of the array, and where the array is (if it’s an array of ints, it’s probably hard to reproduce, but a decent array of structs it can happen every time). Computer has plenty of oomph (dxdiag attached). Seems minor but getting a tad annoying so thought it was worth a report.

To reproduce in blank UE4.16.3:

  1. Make a struct, give it a property of type Name.
  2. In a blueprint class, add a blank function and a LOCAL variable that is an array of your new struct (doesn’t seem to happen as often on a class variable).
  3. In the array defaults, add a couple of entries (or several, to be sure). Switch between the entries, changing the “Name” property and without hitting Enter, click another “Name”. You should notice that sometimes it will select the “Name” text properly (blue highlight), sometimes it will not select it at all, and sometimes it will select it, but the selection is grey without focus and your typing doesn’t work until you select it properly.

If it doesn’t work, try adding more to the struct type and/or more entries to the array.

Hello Spoondog,

I was able to reproduce this issue on our end. I have written up a report and I have submitted to the developers for further consideration. I have provided a link to the public tracker. Please feel free to use the link provided for future updates.
