[Bug] Widget animations only play 1 frame in the editor

I am absolutely sure. I controlled this with a single checkbox.

I had the same problems on other methods running animations. For example I wanted to update the styles when a widget is selected / deselected in editor to show a “focused” style:

#if WITH_EDITOR
/*
void UUserWidgetNavigatable::OnSelectedByDesigner() {
    Super::OnSelectedByDesigner();
    SetStyleFocused();
}

void UUserWidgetNavigatable::OnDeselectedByDesigner() {
    Super::OnDeselectedByDesigner();
    SetStyleDefault();
}
*/
#endif // WITH_EDITOR

In which the SetStyle… are blueprint implementable and play an animation. Play forward for focus animation, play reverse to undo focus animation. Same result.
I am creating another post for more editor animation weirdness…

UMG animated brush material parameter has the wrong default value

I am clueless why the editor doesn’t do these things. Right now it takes an enormous amount of time to iron these things out.

Ruling out it is PC / project specific… Does it work for you?
