provide an action to add an error to a resource

Great ideas. I'm starting to think how ngrx-json-api can be used for forms as well!!!

What about also adding a resetResourceAction. This will reset the resource to the persistent resource if found.

sounds good to me.

I would also have to code to dynamically bind forms. But it needs some further cleanup.

resetResourceAction is actually already available as rollback, but just as apply need may need some further parameters to decide what to rollback. Can be addressed in #93.
