This post is about something I faced and how I managed to get it working as someone else might face the same problem. If you have a better way to deal with this very problem please do share with me.
While doing the challenge for this lecture I faced a strange behavior. I did complete the challenge but for future proofing the reference/bindings I went to rename the Buttons. And every time I renamed a Button, the engine crashed with a long call stack which I didn’t completely understand.
What I inferred from this was the engine must have cached the reference/binding and crashing the engine as renaming the widget may not update the pointer reference. So as a workaround, I commented out the
UPROPERTY(meta = (BindWidget)) for each widget I wanted to rename, compiled the code and renamed it successfully as the binding no longer exists. Then uncommented and recompiled and made sure everything was working.
