PresentationTreeDataProvider.pagingSize

[paprophet]

when open bim file,the brower console this:

Warning |presentation-components.Hierarchy| PresentationTreeDataProvider.pagingSize doesn't match pageOptions in PresentationTreeDataProvider.getNodes call.
Make sure you set PresentationTreeDataProvider.pagingSize to avoid excessive backend requests.

but in code,no use the PresentationTreeDataProvider
Presentation.initialize method must set pagingSize ??

initPromises.push(Presentation.initialize({
activeLocale: IModelApp.i18n.languageList()[0],
}));

The warning originates from right here: https://github.com/imodeljs/imodeljs/blob/5b8fd1fd7e8501ad0a252fd9d7e79c7d6a620821/presentation/components/src/presentation-components/tree/DataProvider.ts#L146-L148

It is possible that you're using some component that uses this provider and doesn't set the pagingSize. Putting the breakpoint at those lines would help identify what that is.

i find the error
in CategoryModelTree.tsx, CategoryModelTree._getTree() method,and pageSize parameter
when open some bim file,console this error, so i want what value set to this pageSize is right?100?200?

The CategoryModelTree._getTree() in our repo is in ModelSelectorTree.tsx source file and you say it's in CategoryModelTree.tsx - do you have a copy of that component locally?

The log message warns you about different page sizes being set on the data provider compared to page size being used when requesting nodes from it. When they're the same, we can save one trip to the backend, so we emit the warning to tell that. I looked at the CategoryModelTree and it looks like it's set up correctly:

• It uses ModelSelectorDataProvider which sets the pagingSize to 5.
• It passes page size of 5 to the underlying tree component - this parameter is used when requesting nodes.

I should also note that CategoryModelTree is deprecated and we're planning to remove it on next major version release. Recommended replacements are ModelsTree and CategoryTree.

i use the ModelSelectorWidgetControl and this include CategoryModelTree ,so have this error

ModelSelectorWidgetControl is @internal and should not be used outside of imodeljs repository.
