This may actually be related to Unreal Engine Issues and Bug Tracker (UE-31777) however, I am experiencing the same issues attempting to create buttons populated with data from an array and add them as children to a scroll box (or vertical box, I tried that too). I’ve had this occur on several projects with both the 4.13 engine and the 4.14. The data will populate before dragging the window, but afterwards, I am unable to clear the children or add new ones.
Hello dragonsomnolent,
After running a few tests I believe that you are correct in that the issue that you are experiencing shares the same root cause as the one mentioned in your post. I do not have a workaround for this issue currently.
Make it a great day
Thanks for your prompt response, I “voted” on the bug, here’s to hoping you gurus can get it sorted out. For NOW, I guess I just won’t let players drag windows
