Form: IM.open.incident or IM.update.incident
There is 2 fields (field with list):
The select function is used for ServiceLevel1 field: select( "name.service", "serviceslevel1", "section","IT")
The select function is used for ServiceLevel2 field: select( "name.service", "serviceslevel2", "section",[ServiceLevel1])
So i select from list on form the value for ServiceLevel1.
Then do the same for ServiceLevel2 - i see droped down list of value for that but when i choose one of them the field stay empty.
