[boskid][2.0.35] active electric network uses network_id == 0

[This is a 1.1 save, migrated to 2.0. Using elevated rails & quality but not space age]

I have a compound entity which embeds a power switch which in turn is connected using a copper cable to a power network. When I inspect this in the debugger, the wire connection shows up like this:

The reported network id is "0". The API docs state: Index of a CircuitNetwork or ElectricSubNetwork which is going through this wire connector. Returns 0 if there is no network associated with this wire connector right now.

But there is a network associated with it (it is my main electrical network and if I click on the big electric pole, it will show me all the stats for the network).

Is the documentation wrong? I have connections where network id is > 0. Or should I use different information to determine whether the wire connector is actually connected (e.g. real_connection_count)?

If possible please attach a save file with reference to this entity in storage.pole so i can investigate state of save file and of specific entity.

Thanks for the report. Issue is now fixed for 2.0.36.

In this specific case issue was that LuaWireConnector returns incorrect value for the network_id when given copper wire connector: this value was 1 less than what LuaEntity::electric_network_id would report when it is connected to an electric network. In 2.0.36 this value will be increased by 1 so it matches value read by LuaEntity::electric_network_id and so a first electric network created in game will properly read network_id of 1. For a workaround you can use the LuaEntity::electric_network_id, but this workaround only works for electric poles, if you would happen to get a copper wire connector from a power switch then this workaround is not available.

thank you for the fix. I will update the mod to require 2.0.36 or newer once that has been released.

I currently use the real_connections_count as an indicator that there are connections and that works well.
