As you probably know SuiteCRM 8 is now using angular framework. Thus, for SuiteCRM 8 views, the javascript entry is no longer supported. There is a new extension mechanism for the SuiteCRM 8 angular frontend.
You can however, change a view to render in the classic view mode and that will render like a regular SuiteCRM 7 view.
Was this added to documentation or is there any implementation of how include JS files are now handled in v8 for Changes Triggers that can work? @clemente.raposo@g.martin
