DirectionalLightShadowFilter's "shadow Z fade length" property doesn't save

[grizeldi]

As title says. Trying to edit a DLSF to display in the scene composer and editing the "Shadow Z Fade Length" field changes nothing visually and resets to 0.0 when I select some other element that opens in the Properties panel and then select DLSF again. This looks like a broken getter/setter in whatever node class is responsible for DLSF to me.

I can reproduce this only if Shadow Z Extend is 0 as well. Looking at AbstractShadowRenderer, it's not a straight-forward setter, so I think the cause is there rather than in the SDK. From what I can see, the SDK simply lists the properties and attaches no specific logic to it.
