addComponentAsRefTo Invariant Violation

You are probably here because you got the following error messages:

addComponentAsRefTo(...): Only a ReactOwner can have refs. You might be adding a ref to a component that was not created inside a component's render method, or you have multiple copies of React loaded.

This usually means one of two things:

  • You are trying to add a ref to an element that is being created outside of a component's render() function.
  • You have multiple (conflicting) copies of React loaded (eg. due to a miss-configured NPM dependency)

Invalid Refs
