react-tags | fantastically simple tagging component for your React | Frontend Framework library

I have a component with a form inside. The fields of the form rely on the state of the component that is updated within the onChange methods. Upon clicking the submit button, the component sends the form fields to the parent component, then updates the store. When the onChange method is called, the error "Maximum update depth exceeded. This can happen when a component repeatedly calls setState inside componentWillUpdate or componentDidUpdate. React limits the number of nested updates to prevent infinite loops."
I can't find the reason why a loop occurs inside the "MemberForm" component.
By debugging, however, I understood that at the change of state (not to the onChange function) the parent component "AggiungiSocio" is also rendered. However, the status of the "MemberForm" component is in no way related to the "AggiungiSocio" component.
What is causing this unexpected rendering? How can I avoid it?

The strange thing is that I also use the "MemberForm" component in the "ModificaSocio" component where I pass the form fields as properties. In this component "ModificaSocio" everything works correctly.

To recap
AddSocio -> MemberForm doesn't work
EditSocio -> MemberForm works

AggiungiSocio
