IHC ELS ELKO Enum variable

Hi,
I’m trying to update a resourse id variable of the type enum in ELS Viewer, I’m using String type in OpenHab.

I get the right value from ELS to OpenHab Selection Sitemap, but get “java.lang.NullPointerException: null” Error when I try to update the Item from OpenHab.

Items-file:
String swFunktionUGG “Funktion uttag” (gUttagGardesGard) {ihc=“0xdefa0f”}

Sitemap-file:
Selection item=swFunktionUGG mappings=[“Motorvärmar automatik”=“Motorvärmar automatik”, “Ständigström”=“Ständigström”, “Avstängd”=“Avstängd”, “Tidur”=“Tidur”, “3 timmar”=“3 timmar”, “Skymningsstyrning”=“Skymningsstyrning”]

ERROR:
