preCommitCallback is ignored due to hooks setting values asynchronously

[Mattia Longhin]

Hello,

First of all, thank you for your work!

I think that there is an issue with preCommitCallback. You call setValues with the result of preCommitCallback and then you use the content of values variable directly.

This does not work because you cannot trust setValues to synchronously change values. Your are providing the old values to the create function.

react-admin-import-csv/src/import-csv-button.tsx

Line 101 in ece80b9

 if (preCommitCallback) setValues(preCommitCallback('create', values));
