    Get model errors after upgrade to 8.8.0


    After upgrading to Umbraco 8.8.0 I am getting the following errors in the Umbraco/default.cshtml view.

    BackOfficeModel does not contain a definition for IconCheckData BackOfficeModel does not contain a definition for IconCheckData IconDeleteData

    The above happens on this piece of code["iconHelper", function (iconHelper) {
                     @*We inject icons to the icon helper(service), since icons can only be loaded if user is authorized. By injecting these to the service they will not be requested as they will become cached.*@
                    iconHelper.defineIcon("icon-check", '@Html.Raw(Model.IconCheckData)');
                    iconHelper.defineIcon("icon-delete", '@Html.Raw(Model.IconDeleteData)');

    I commented out, for now, to get the back office running.

    Regards Farhad

    Same problem here.

    Tried to comment them out, but then I'm getting another error when opening my home-node. So, back to 8.7 I guess for now.

    Same thing. I upgraded from 8.6.1 to 8.8.0 and started getting the same error but when I commented out these lines I got my back office up running and (at least now) staying in 8.8.0.

    From what I can tell this is due to an issue when building the project. I solved this by clearing the bin folder (Except the Roslyn folder) and rebuilding the project.

    This creates the dll files again and when you launch the website Umbraco will guide you through the upgrade.

    You can see if your problem is caused the same way by peeking at the definition of BackOfficeModel in the Default.cshtml in Umbraco/views.

    It's supposed to look something like this:

    Had what appears to be the same problem. I deleted the ClientDependency temp folder and then it worked again.

    The above haven't worked here. Upgrading from 8.12.0 to 8.16. Still cannot resolve IconCheckData and IconDeleteData :(

    @Tommi's tempy fix of commenting the lines out gets the back office up. Needs a proper fix though.
