OH3 MainUI stepper widget issues commands on it own on the page load

xsherlock · October 22, 2021, 2:16pm

Hi All,

I noticed very curious behavior of the OH3 mainUI, that I think is a bug but maybe it is intended and hopefully there is a workaround.

So I have a UI page with 10 stepper widgets to control the heating valve opening. They are being pooled by the backnet binding and that works perfectly. Some external controler does the valve control. So my openhab UI is mainly to view, but I used steppers to be able to manualy intervene . The steppers have a step set 5% to click less.

Now what happens when I open a layout page is that this widget immediately without being asked sends commands to the valve controller rounding up all the values to the 5 % step

Why , can that be prevented.
All items have autoupdate set to false.

What version?
Spontaneous commands from (some?) widgets were addressed in 3.1 release.

Not related.

3.1.0 - Release Build

rossko57 · October 22, 2021, 2:46pm

Sounds like they missed this one. Open a Github issue - widgets should simply not send commands unless poked by the user.

(you can get endless loops if two UIs are open at once )

## The problem A wigget is sending spnatagnus commands to the items, rounding …them up to the stepper step ![image](https://user-images.githubusercontent.com/23699880/138481735-d241fb99-469a-4cd9-ac21-82dba7593c42.png) ## Expected behavior Should not happen. ## Steps to reproduce Create item modified by some external controler. On loading the UI layout page. observe the log it will show a number of the commands issued to the items in the steppers on the page code for the stepper ```yaml component: oh-stepper-item config: item: Archive_01_Postriscaldo_valve min: 0 max: 100 scale: true unit: "%" releaseOnly: true commandInterval: 1000 step: 5 title: Archive 01 ``` ## Your environment ```yaml runtimeInfo: version: 3.1.0 buildString: Release Build locale: en-IT systemInfo: configFolder: /etc/openhab userdataFolder: /var/lib/openhab logFolder: /var/log/openhab javaVersion: 11.0.11 javaVendor: Azul Systems, Inc. javaVendorVersion: Zulu11.48+21-CA osName: Linux osVersion: 5.4.0-88-generic osArchitecture: i386 availableProcessors: 2 freeMemory: 26034576 totalMemory: 166723584 bindings: - astro - co7io-bacnet - mqtt - telegram - weatherunderground clientInfo: device: ios: false android: false androidChrome: false desktop: true iphone: false ipod: false ipad: false edge: false ie: false firefox: false macos: false windows: true cordova: false phonegap: false electron: false nwjs: false webView: false webview: false standalone: false os: windows pixelRatio: 1.25 prefersColorScheme: light isSecureContext: false locationbarVisible: true menubarVisible: true navigator: cookieEnabled: true deviceMemory: N/A hardwareConcurrency: 24 language: en-US languages: - en-US - en onLine: true platform: Win32 screen: width: 4096 height: 1728 colorDepth: 24 support: touch: false pointerEvents: true observer: true passiveListener: true gestures: false intersectionObserver: true themeOptions: dark: light filled: true pageTransitionAnimation: default bars: filled homeNavbar: default homeBackground: default expandableCardAnimation: default userAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.81 Safari/537.36 timestamp: 2021-10-22T15:30:23.423Z ``` ## Browser console  No erros in console but wisible commands send ```Update iconUseState to true 16.app.js:1 {"item":"Archive_01_Postriscaldo_valve","min":0,"max":100,"scale":true,"unit":"%","releaseOnly":true,"commandInterval":1000,"step":5,"title":"Archive 01","iconUseState":true} app.js:38 Sending command to postriscaldo_valve_reset_switch: ON app.js:38 Sending command to Archive_03_Postriscaldo_valve: 50 app.js:38 Sending command to Archive_07_Postriscaldo_valve: 30 app.js:38 Sending command to Archive_04_Postriscaldo_valve: 35 app.js:38 Sending command to Archive_02_Postriscaldo_valve: 35 app.js:38 Sending command to postriscaldo_valve_reset_switch: ON app.js:38 Sending command to Archive_07_Postriscaldo_valve: 35 app.js:38 Sending command to Archive_06_Postriscaldo_valve: 50 app.js:38 Sending command to Archive_06_Postriscaldo_valve: 45 app.js:38 Sending command to Archive_05_Postriscaldo_valve: 65 app.js:38 Sending command to Archive_04_Postriscaldo_valve: 30 app.js:38 Sending command to Archive_06_Postriscaldo_valve: 50 ``` ## Browser network traffic  ## Additional information
