I've been developing my own PING/PONG for a websocket application and needed to manage the state of whether PONG has been received. To make sure I don't accidentally change the variable and to avoid name collisions I've encapsulated the variable into get and set methods and made funny changes to ma…

Might try adding definition ( // apps singleThreaded: true )

For my own curiosity.... Would that mean any comm's sent to the app would potentially require some kind of wait for the platform while the app deals with the call / data being processed from a previous call?

Should queue up and be processed FIFO if I’m reading it right. [image] [2.2.9] singleThreaded option for apps/drivers 🚧 Developers This was in release notes but way down, so I figured it deserves a special mention here in Developers section. So... singleThreaded is a bool…

Thanks for the feedback. I tried using both singleThreaded: true and atomicState. The glitch has improved but has not completely gone away. Any other thoughts welcome! In the event I can't figure this out, where can I report this potential bug to Hubitat? Thanks!

I think you're probably racing the state caching behavior since you set and query the same state members within the same methods. Try pulling from state once within the method and operate only with local values, then update state at the end of the method (if needed).

By method, do you mean the high level commands defined in my device or functions like void setReceivedPongToTrue() { if (enableLogging) log.debug "setReceivedPongToTrue()" state.elephant = "TRUE STRING" if (enableLogging) log.debug "receivedPong set to: ${state.elephant}" } The f…

I only glanced at the methods you excerpted in your post. But you set state.elephant and then immediately print its value to the log. I think you are saying that the print doesn't match the value you set it to. Correct? If so, sounds like a caching issue to me.

The value printed matches the values I set. Here's the problem illustrated Time 0: setReceivedPongToFalse() Time 1: setReceivedPongToTrue() Time 30: getReceivedPong() // returns FALSE instead of TRUE! I'm guessing for some reason the actual changing of the state occurred in reverse order. Time 1…

You could try this instead of state and atomicState: @Field static Map sharedState = new java.util.concurrent.ConcurrentHashMap() You would put values into that just like any map: sharedState["elephant"] = "TRUE STRING" and pull them out the obvious way... You would need this: import groovy.tr…
