Formik: Update field values from outside and rerun validation

[kennyx46]

Bug, Feature, or Question?

Question

Current Behavior

mapPropsToValues updates the form values only once if enableReinitialize is false. Is this correct behaviour? Should I always set it to true to make mapPropsToValues update form every time?

Also updating props via mapPropsToValues does not run the validation. Is this expected behaviour?
How can I run the validation manually?

Hi @kennyx46 ,

One option I see: in your component you'd need to store reference to <Formik>'s FormikProps that are passed to child FAAC when the FAAC is rendered.
Then on componentWillReceiveProps() or similar, call FormikProps.validateForm();

Let us know if it worked ;-)
Cheers

^^ correct,

there is a PR open for a new onReinitialize prop. Would solve lots of use cases
