Form Input Behaves Unexpectedly in Edge on Pleasanter

Answer

The cause is Edge's autofill feature, not Pleasanter itself.
Set the "DisableAutoComplete" parameter to "true" in General.json to suppress this behavior.

Overview

When entering data into a web form in Edge, a "previously used" suggestion may appear. If a user selects this suggestion, Edge may also autofill values into other related form fields. This autofill behavior is a feature of Edge, not of Pleasanter.

If the autofilled values are not what was intended, apply the mitigations below.

Mitigation 1 — Pleasanter configuration

Set the "DisableAutoComplete" parameter to true in "General.json".

General.json
{
    "DisableAutoComplete": true
}

This outputs autocomplete="off" on form elements, suppressing browser autofill.

Note that Edge may not honor the autocomplete="off" attribute on form elements. If the problem persists, combine this with Mitigations 2 and 3 below.

Mitigation 2 — Bulk configuration in an Active Directory domain environment

In environments managed with Active Directory domain or a cloud MDM solution, Edge's autofill feature can be disabled organization-wide. Refer to the following documentation for details.

  1. On-premises (Active Directory + GPO): Microsoft Edge policy settings
  2. Cloud (Intune / Azure AD + MDM): Configure Microsoft Edge with Intune

Mitigation 3 — End-user action

Users can address the issue on their own by either of the following methods.

  1. Disable autofill in Edge via "Settings" → "Passwords and autofill"
  2. Clear browsing data in Edge via "Settings" → "Privacy, search, and services"
