@exyi I moved this issue of nullifying sub view models in separate thread/post.  
To here: [[view models / page structuring series] Hide/Show page sections/containers by nullifying their view models](https://forum.dotvvm.com/t/view-models-page-structuring-series-hide-show-page-sections-containers-by-nullifying-their-view-models/149)

> Although I have a working validator to handle the [Required] property, on Production environment, on .NET Core, .NET 8, errors still show in the Console tab in browser, cluttering the client-side maintenance/debugging side of work. I don’t know how to disable/mute/treat these as to not appear anymore as they are not needed (validation is already taken care of).

This is now the single issue of this thread.
