When editing the "Extended Pan ID" in ioBroker Adapter Zigbee.x the Adapter shuts down with following
error messages. I don't know if this is normal and will not work with the zigbee-coordinator v1.0? Maybe it's
a problem of the adapter?

Error-messages are in this order:

• Unable to apply ExtPanID changes: Error: SRSP - SYS - osalNvRead after 0,2ms
• Starting zigbee-herdsman problem : "startup failed - configuration-adapter mismatch - see logs above for more information"
• Failed to start Zigbee
• Error herdsman start

With default Ext-ID: DDDD.. it works fine.

It seems that you can not edit the subnet mask when assigning a manual IP address for LAN/WiFi.
If you reboot the coordinator with the greyed out subnet mask input field, it won't be reachable as there is no subnet given.
