UncheckedException during SmartApp install

(Randall Olson) #1

I am getting the following exception in my logs when installing a SmartApp I’ve written. The SmartApp is just a simple test for creating child devices.

9:30:26 AM:
physicalgraph.exception.UncheckedException: java.lang.Exception: Throwable caught while executing. 

There is no other description of the exception or information about what is going wrong. The exception happens after the refresh() call in the initialize() method. I would appreciate it if anyone had any insight as to why I am getting the exception. Code below.

Custom DeviceType:

metadata {
    definition (name: "Proxy Switch", namespace: "rolson16", author: "Randall Olson") {
        capability "Actuator"
        capability "Switch"
        capability "Polling"
        capability "Refresh"
        command "setSwitchState"

    // simulator metadata
    simulator { }

    // tile definitions
    tiles {
        standardTile("switch", "device.switch", width: 2, height: 2, canChangeIcon: true) {
            state "on", label: '${name}', action: "switch.off", icon: "st.switches.light.on", backgroundColor: "#79b821"
            state "off", label: '${name}', action: "switch.on", icon: "st.switches.light.off", backgroundColor: "#ffffff"
        standardTile("refresh", "device.switch", inactiveLabel: false, decoration: "flat") {
            state "default", label:'', action:"refresh.refresh", icon:"st.secondary.refresh"

        main "switch"

def parse(String description) { }

def setSwitchState(value) {
    sendEvent(name:"switch", value: value, displayed: false)
    log.debug "${device.currentState("switch").value}"
    return null

def on() {
    parent.changeSwitchState(this, "on")
    sendEvent(name:"switch", value: "on", displayed: false)

def off() {
    parent.changeSwitchState(this, "off")
    sendEvent(name:"switch", value: "off", displayed: false)

def poll() {

def refresh() {

I’d suggest you’re debugging too much code all in one shot.
some things I would do…
-comment out the refresh call
-verify child devices are being created
-uncomment refresh, replace the code within the loop with a log.debug to verify your state maps contain what you think they contain…

as an FYI, I’ve not been able to execute deleteChildDevice without generating an error, advise if you are.

as an additional FYI, there is no need to explicitly delete the child devices with the uninstall method, they are deleted correctly.

Thanks for the response, Mike.

-I tried commenting out the refresh() call with the same results.
-I was able to confirm my code was creating a child device, though I don’t get a chance to see it in the mobile app.
-I also confirmed that my maps contain the proper data.

I did another test to confirm that the state is getting set properly in my child device during the refresh. The SmartApp seems to process correctly all the way through the initialize() method.

Only thing I can really think of is maybe I am creating my child devices incorrectly or the document type is bad so that they cannot be properly attached to the hub/location/UI. I haven’t found any really good documentation on addChildDevice.

well then start commenting out the sections in the initialize until you find the culprit, since it wasn’t refresh…
Feel free to troll through this app, if it’s any help…

Ok, it appears to be a problem with the way I am working with my child devices. I got something similar working in another app. Now if I can only figure out why setLocationMode() doesn’t work when called…

Thanks Mike for the responses and suggestions!
