viewer tree-widget question

Hi ,When I open a file that doesn't contain any geometric elements, the tree doesn't display any models, even though the file does contain models. After I create a geometric element, the tree still doesn't update. I have to reopen the file for the model to appear in the tree. Is this a bug or expected behavior? Is there a way to make the tree show models even when opening a file without geometry?

Reopen the file

Hi. You can configure Models tree to show empty models by passing in this prop to ModelsTreeComponent:

<ModelsTreeComponent
  hierarchyConfig={{
    showEmptyModels: true,
  }}
/>

Models tree should update when elements are inserted into an iModel. Can you show the snippet of code adding elements to iModel?

Thank you ! What about category ? The CategoriesTreeComponent componet doesn't have the hierarchyConfig prop. I use a tool , CreateLineStringTool , to insert elements

Am I right to think this is an Electron app? What are the resolved versions of these packages?

@itwin/presentation-backend
@itwin/presentation-frontend
@itwin/presentation-components
