I have a small Angular2 project based on the Angular2 Seed project that I am trying to upgrade to Angular2 RC5.
My project has a few features, one of them called home
. Home component uses a child component called create-report-card-form
. I have declared both the home and create-report-card-form
components in the home.module
(see code below) and get this error:
Unhandled Promise rejection: Template parse errors: Can't bind to
'currentReportCardCount' since it isn't a known property of
'create-report-card-form'.
- If 'create-report-card-form' is an Angular component and it has
'currentReportCardCount' input, then verify that it is part of this module.
