FrontStage error

[Paolo-lab]

Hello good morning, we have been implementing for some time now the possibility in our app to use the frontstage to be able to divide the view screen into multiple parts.

We have a specific problem on a project (which unfortunately I can not share)

in the ViewSetup , the program searches for a viewId through the getFirstViewDefinitionId and then extracted the viewId uses it to create the viewstate, and the program fails when I try to create the viewstate. from what I see it seems that it does not find the specific viewId and then fails in the constructor of the ToolSelectionSyncHandler class

I attach two images that of the code that I use (taken from the examples)
and the error on chrome

Thanks for your continued support

Hi @Paolo-lab. It doesn't look like the error is related to the piece of code you're showing.

The error is caused by a unified selection viewport component being passed an undefined iModel. To find the culprit, you can try looking for usages of viewWithUnifiedSelection function:

import { ViewportComponent } from "@itwin/imodel-components-react";
import { viewWithUnifiedSelection } from "@itwin/presentation-components";

const UnifiedSelectionViewport = viewWithUnifiedSelection(ViewportComponent);

function MyComponent() {
  // `imodel` is undefined here:
  return <UnifiedSelectionViewport imodel={imodel} />;
}

Hi @aruniverse , I'm not clear on what I should post, the entire viewsetup.tx file?

We have no idea what your getFirstViewDefinitionId function is doing, so at minimum please share that, and whatever else you are able to share

I understand that it is really difficult to understand with so little information and I apologize for the inconvenience. I attach part of the code of getFirstViewDefinitionId in debugging phase, as you can see the program finds a defaultView "0xf0000000050"...

Hello good morning, I am continuing to search for the problem on this specific model

in the getFirstViewDefinitionId, I removed the queryDefaultViewId which for some reason (unknown to me) returns an incorrect defaultViewId, and everything seems to work

Thank you for the support and I apologize to you if I have created difficulties

Thank you
