when I restart the gateway I have few message like this one:
Tried to unregister a path/listener combination that is not present in the model. Value: TagSubscription(path=[default]TVG/SYS/SUP01/00001/TS/ETAT_PORT_03, listener=com.inductiveautomation.ignition.common.expressions.functions.TagFunction@1d5d91c8)
I have below message flooding the logs. Appears for each tag. Version 8.0.15.
Tried to register a path/listener combination that is already in the model. Value: TagSubscription(path=[default]OWPPWINCC/MOV2021_OPEN_FB, listener=com.inductiveautomation.perspective.gateway.binding.expression.ExpressionBindingTagListener@18009de2)
After the warning message, I also have the next errors:
"java.lang.IllegalArgumentException: missing event subscriber for an annotated method. Is com.inductiveautomation.perspective.gateway.binding.expression.ExpressionBindingTagListener$SessionEventListener@9b36db7 registered?
Hi in the gateway logs, if you hover over the magnifying glass to the right, it should tell you which project, view, component, and property that this error is coming from. I’ve seen this error occur when a expression binding references the same tag path more than once e.g. {tagA} + {tagA}. Therefore if you can restructure your expression to contain only one reference of the tag path, then the error would go away.
