There are few errors in the fourth tutorial in the documentation (https://doc.ez.no/display/DEVELOPER/Extending+PlatformUI+with+new+navigation).

Tutorial 4, step 3:
Missing the line:

service: Y.eZ.DashboardBlocksViewService,

in the last code fragment, inside app.route. Without it the dashboard elements are not loading correctly and console is throwing an error when accessing the dashboard from the /ezconf/list URL.

Tutorial 4, step 6.2:
There is no information that configuration in file yui.yml should be changed to:

ezconf-listviewservice:
    requires: ['ez-serversideviewservice']
    path: %extending_platformui.public_dir%/js/views/services/ezconf-listviewservice.js

which means changing the "requires" parameter. Without that change lists is not showing correctly and the console is throwing an error.

Tutorial 4, step 6.2, fixing the link issue:
Code fragment where we are throwing an event should look like this:

this.fire('navigateTo', {
    route: {
        name: link.getData('route-name'),
        params: {
            id: link.getData('route-id'),
            languageCode: link.getData('route-languagecode'),
        }
    }
});

This way we don't need to subscribe this event in the "ezconf-listviewservice.js" (we could just skip this part of the tutorial) and it still will be working as expected.
Without that change after clicking any link from the list we don't move to any location and the console is throwing an error.

Tutorial 4, step 7:
Analogical to previous fix. Correct code to throw an event:

this.fire('navigateTo', {
    route: {
        name: 'eZConfListOffset',
        params: {
            offset: offset,
        }
    }
});

tutorial 4, step 8:
Analogical to previous fix. Correct code to throw an event:

this.fire('navigateTo', {
    route: {
        name: 'eZConfListOffsetTypeIdentifier',
        params: {
            offset: "0", // offset: 0 does not work, because of a bug in PlatformUI
            typeIdentifier: select.get('value'),
        }
    }
});
