Root Cause Analysis

When the user exports files and clicks "back" on the result page, ZipFileProcessResultWidget::backPage() only emits changeWidget to switch pages but does not emit clearWidget to reset the selection controls. This leaves previously selected files visible when the user returns to the selection page. The same backPage() pattern in ErrorWidget and two other callers correctly emits clearWidget before changeWidget, confirming the omission as the root cause.

Fix

Added emit TransferHelper::instance()->clearWidget(); before the existing changeWidget signal in backPage(), matching the established pattern used by ErrorWidget::backPage() and other callers in the same project.

Change Safety Assessment

Code Safety

• Risk Level: Low
• Single-line addition of a signal emit; no signature change, no public member modification, no history revert
• Target function backPage() was introduced in commit f5975eee without clearWidget(); this change does not revert any historical fix

Business Impact Scope

Affects the data migration backup export flow: when users return to the selection page after completing a file backup export, their previous file selections are now cleared. No other navigation paths or business modules are affected.

Verification Suggestion

Test the file export → back navigation path to verify selections are cleared. Verify normal export flow and other page navigation paths show no regression.

根因分析

用户导出文件后点击返回时，ZipFileProcessResultWidget::backPage() 仅发射 changeWidget 信号切换页面，未发射 clearWidget 信号清空选择控件状态，导致返回选择页面时历史选择仍保留。同项目中 ErrorWidget::backPage() 等 3 处正确范式均在切换页面前先发射 clearWidget，确认遗漏为根因。

修复方案

在 backPage() 的 changeWidget 信号前新增 emit TransferHelper::instance()->clearWidget();，与同项目内 3 处正确范式保持一致。

改动安全评估

代码安全评估

• 风险等级: 低风险
• 单行信号发射语句新增，未改函数签名、未改公开成员、未撤销历史修复
• 目标函数 backPage() 自引入以来从未包含 clearWidget() 调用，本次改动不撤销任何已有修复

业务影响范围

影响数据迁移备份导出流程：用户完成文件备份导出后返回选择页面时，历史选择将被清空。其他导航路径和业务模块不受影响。

验证建议

测试文件导出后返回路径，验证选择已清空。验证正常导出流程及其他页面导航路径无回归。

Reviewer's Guide

The backup export result page now clears previously selected files before returning to the selection page, aligning its back-navigation behavior with the established widget pattern.
