Notice

Not sure why arrow function is not working, we just use a normal function

Usage

1. Create a hook for to the component, use it outside of the form.

this.dimensionRef = React.createRef();

2. Then in the import file function

this.dimensionRef.current.getWrappedInstance().onImport(message.file.input.dimension[0]);

3. In the finish function

this.dimensionRef.current.getWrappedInstance().onFinish();
