Now the Hue groups are not working anymore. The old release from 11.11.16 was working fine. Has something changed since than?\r\n\r\nFollowing error in the log when I turn off and on an light of that group:\r\n\r\n```\r\n[pse.smarthome.core.items.GenericItem] - failed notifying listener '[gHueLights_Wohnzimmer_Color (Type=GroupItem, BaseType=ColorItem, Members=8, State=null, Label=Wohnzimmer, Category=colorwheel), Licht_Farbe_WZ_TV_Rack_Rechts, null]' about state update of item java.lang.NullPointerException: {}\r\n```\r\n\r\nAlso the Paper UI control tab Show internal error 500. I am also not able anymore to switch an Hue Color Group on and off. As suggested by Kai I tried to remove the (:Color:Max) from my goup but still the same behaviour. If I remove the groups from the item definition than all is working correctly also the paper ui control tab is working and showing all things with values again.\r\n\r\nitem config:\r\n```\r\nGroup:Color:MAX gHueLights_Alle_Color \"Alle Lampen\" \r\n\r\nColor Licht_Farbe_WZ_TV_Rack_Oben       \"TV-Rack Oben\"       <colorwheel> (gHueLights_Alle_Color)     [ \"Lighting\" ] { channel=\"hue:0200:00178816e03f:1:color\" }\r\nColor Licht_Farbe_WZ_TV_Rack_Links      \"TV-Rack Links\"      <colorwheel> (gHueLights_Alle_Color)     [ \"Lighting\" ] { channel=\"hue:0200:00178816e03f:2:color\" }\r\n```\r\n\r\nsitemap:\r\n```\r\nColorpicker item=gHueLights_Alle_Color label=\"Alle\" \r\n```\r\nRegards René"}}
