"findDOMNode is deprecated" on data type selection

[iosonosempreio]

Once data is loaded on the data grid, the first time you try to change a data value (eg. from number to date) the app triggers this warning.

Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of Transition which is inside StrictMode. Instead, add a ref directly to the element you want to reference. Learn more about using refs safely here: https://fb.me/react-strict-mode-find-node

This is an issue with react-boostrap, that uses a deprecated react api. Should be fixed in a future update of the lib and it should not be a problem in production.
