PanelUI Slider Widget sends NULL to HSB Dimmer Item

I’ve found my way here because I cannot use a PanelUI Switch Widget effectively with my HSB Bulbs. I’ve tried to map the switch to the Dimmer Channel of my HSB Thing without luck. Am I doing something wrong there? The panel widgets don’t seem to update when an HSB item is switch otherwise. This may have to do with the way my linking is set, but I’m just not sure.

So when I try using a Slider, I set the sider to the HSB item and then Min = 0, Max = 100, Step = 25 with a Veritical orientation. Sliding to 0 gets me the following.

Item Definition
Dimmer HSB_Light_Joeys_BR “Joey’s Bedroom Light” [“Lighting”]


I believe I’m past this at this point. Configuration for those who follow.

I’ve configured my HSB Lights as Switches in my items file. I’ve put the Switchable tag on them, and then made sure they are linked to the Dimmer Channel in HABmin. Now they are switches in PanelUI, and are functioning correctly. So the Slider widget is not needed.
