Performance: SceneDataTransformer always re-runs transformations on activate #717

Closed torkelo closed 6 months ago

torkelo commented 6 months ago

Transformations can be very slow (Especially if they involve parsing dates). Currently SceneDataTransformer does the transformations always on activate which can make going into panel edit and back very slow / sluggish for panels with slow transformations.
