Model -> non-semantic items not shown when state description metadata added

mkokoszka · October 8, 2021, 11:26pm

Dear community,
I have the following problem. I created my model and added all semantic items. Then I added some non-semantic groups and items. When I select model at the WebUI and then check the option to show non-semantic items everything is ok and they are displayed at the tree as long as I will not add the state description metadata to such non-semantic group item. After adding metadata (e.g. State description) item disappears from the tree.

Question is why? How to prevent such behavior. It is very convenient when the whole “logical” structure can be seen on tree. Otherwise such “hidden” items assigned to some parent groups can easily disappear among large numbers of other items.

Best regards
Marcin

Model tree stops showing childs of non-semantic group item if StateDescription metadata is added

bug main ui

## The problem I have a couple of items bound to the ZWave switches. They sit in the proper semantic location of my house. I created a non-semantic group to capture all lights in my house. The group has aggregation `Group:Number:SUM` to show the count of lights that are ON (however, the issue is valid for other aggregations like AVG for temperatures etc.). The main UI model tree is shown correctly (if I tick "show non-semantic"). However, if I add metadata, for example, StateDescription or Default List Item widget, then all child items disappear in the tree view. If I remove metadata, they are visible again. When children items are not visible, the relationship is still there, the group is updated accordingly, and only the tree view is affected. This issue happens only for situation if the child Items are semantic ones, but the parent group is non-semantic. I tested out and that aggregation doesn't have any influence, so simply a plain Group item with any child items are sufficient to get this issue. ![Feb-24-2021 09-05-42](https://user-images.githubusercontent.com/4218395/108967351-b1bfe700-767f-11eb-84cb-e9fab1767ce0.gif)  ## Expected behavior Non-semantic group should show child items no matter what metadata is configured on non-semantic group Item.  ## Steps to reproduce 1. Create items and corresponding group using textual form. Items should be semantic ``` Group gTempSum Number TempItem1 (gTempSum) ["Point"] Number TempItem2 (gTempSum) ["Point"] ``` 2. Go to the Model view and tick "Show non-semantic" 3. Click on the `gTempSum` group item and add metadata, e.g. `Default List Item Widget` and save it. 4. Notice that the Group item in the Model view stopped showing child items 5. Remove the metadata from Group Item. Model view starts showing child items again.  ## Your environment OH3.0.1 + Raspbian RPi4B  ```yaml runtimeInfo: version: 3.0.1 buildString: Release Build locale: pl_PL systemInfo: configFolder: /etc/openhab userdataFolder: /var/lib/openhab logFolder: /var/log/openhab javaVersion: 11.0.10 javaVendor: Azul Systems, Inc. javaVendorVersion: Zulu11.45+27-CA osName: Linux osVersion: 5.10.11-v7l+ osArchitecture: arm availableProcessors: 4 freeMemory: 82669320 totalMemory: 194904064 bindings: - amazonechocontrol - astro - exec - hpprinter - http - mqtt - network - ntp - openweathermap - robonect - samsungtv - spotify - systeminfo - zwave clientInfo: device: ios: false android: false androidChrome: false desktop: true iphone: false ipod: false ipad: false edge: false ie: false firefox: false macos: true windows: false cordova: false phonegap: false electron: false nwjs: false webView: false webview: false standalone: false os: macos pixelRatio: 2 prefersColorScheme: dark isSecureContext: true locationbarVisible: true menubarVisible: true navigator: cookieEnabled: true deviceMemory: 8 hardwareConcurrency: 8 language: pl languages: - pl - en-US - en onLine: true platform: MacIntel screen: width: 1440 height: 900 colorDepth: 30 support: touch: false pointerEvents: true observer: true passiveListener: true gestures: false intersectionObserver: true themeOptions: dark: dark filled: true pageTransitionAnimation: default bars: light homeNavbar: default homeBackground: default expandableCardAnimation: default userAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 11_0_1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36 timestamp: 2021-02-23T15:34:18.019Z ``` ## Browser console  There are no errors in console.

But I captured the request for getting list of items focused on the affected items.

Thank you. I will keep an eye on issue at GitHub.

@Wolfgang_S @Dibbler42 I have run into the same problem. There is no solution?

Wolfgang_S · October 29, 2021, 4:17pm

I am not aware of any solution. An issue is open in github ( see above link ) and as far as I understand as long as it is not closed the problem still exists.

davidtorres · November 2, 2021, 8:55am

Thank you very much for your answer.

I have looked at Github and it seems open, yes. We will be up to date to see if there is a solution.

Greetings.

Hello again,

For my specific case in which I wanted to incorporate the value unit in the widgets, I have found another way to do it without having to go through this bug.

My solution is inside a widget to fill the label field with an expression. I attach an example:

Greetings, I hope it helps someone.
