So I have an app. It creates children device(s) and then subscribes to them. I also have a way to remove child devices from within the app. Except that any code I put in place to do this always throws an error.
I’ve tried multiple iterations of code, placing them in various places, etc. It seems like the unsubscribe doesn’t happen right away, so the below code doesn’t work.
unsubscribe(getAllChildDevices().find(){it.name == deviceID})
deleteChildDevice("${app.id}/${deviceID}")
Gives:
error physicalgraph.exception.ConflictException: Device still in use. Remove from SmartApps, Dashboards, or Hello Home, then try again
I’ve also tried it like this (just code snippets, the program has more):
def updated() {
unsubscribe()
initialize()
def mySwitches = getChildDevices()
subscribe(mySwitches,"switch",processSwitches)
}
def initialize() {
deleteChildDevice("${app.id}/${deviceID}")
}
In this case, the unsubscribe works before the delete, but the delete gives this error (I’m guessing because the actual delete doesn’t happen until the update method ends):
error org.hibernate.ObjectDeletedException: deleted object would be re-saved by cascade (remove deleted object from associations): [physicalgraph.app.EventSubscription#d0dc0486-c7b3-4fc6-842a-604addbb2c06] @ line 266
I’ve done many searches in Google and these forums and can’t find a solution anywhere. Has anyone come across this and found a way to handle the race conditions between unsubscribe and deleteChildDevice?
