…progress The re-submission guard skipped the canSubmit early return whenever submissionAttempts exceeded 1. canSubmit is also false while isSubmitting is true, so every handleSubmit call during a pending submission fell through to onSubmit and ran it concurrently. Restore the early return while a submission is in progress so subsequent calls invoke onSubmitInvalid and return, matching the behavior before the re-submission re-validation path was added. Re-submission of an invalid, idle form still re-runs field validators to clear stale errors.

Check isSubmitting independently of canSubmit.
When canSubmitWhenInvalid is true, canSubmit remains true during a pending submission. A second handleSubmit() call therefore skips this guard and can invoke onSubmit concurrently. The devtools submission override also bypasses the guard. Check isSubmitting before the canSubmit branch, then preserve the existing revalidation behavior for idle invalid forms. Add a regression case with canSubmitWhenInvalid: true.

Changes
Fixes #2279.
handleSubmit()no longer callsonSubmitagain while a submission is still in progress.Since #2120, the
!canSubmitearly return in_handleSubmit(packages/form-core/src/FormApi.ts) applies only whensubmissionAttempts <= 1.canSubmitis also false whileisSubmittingis true, so eachhandleSubmit()call during a pending submission skipped the early return and calledonSubmitagain.The early return now also applies while
this.state.isSubmittingis true. Those calls invokeonSubmitInvalidand return, as they did before #2120. An idle, invalid form on attempt > 1 still re-runsvalidateAllFields('submit')to clear stale field errors, so the #2120 behavior is unchanged.One judgement call: calling
onSubmitInvalidfor the in-flight case restores the pre-#2120 behavior. Returning silently is the alternative, since the form is busy, not invalid. That is a one-line change if you prefer it.The new test in
packages/form-core/tests/FormApi.spec.tscallshandleSubmit()three times whileonSubmitis pending. Without the fixonSubmitruns 3 times and the test fails; with the fix it runs once.FormGroupApi._handleSubmitnever had an in-flight guard, so it is not part of this regression and is not changed.Checklist
pnpm test:pr, or these tests do not apply to this pull request.Release Impact
Summary by CodeRabbit
onSubmitcalls while a form submission is in progress. Invalid submission attempts still trigger validation handling.
