finding(components): the data-table's document-level pointerdown commit exists because "injected widgets have no blur handler" — field widgets now deliver a host `onBlur`

[os-sam]

Found while implementing #6802 (PR #6858). Filed rather than folded in: the
repair is in packages/components, outside that card's file surface, and it is
a behaviour change of its own.

What

packages/components/src/renderers/complex/data-table.tsx commits an inline
edit made in a HOST-INJECTED widget through a document-level pointerdown
listener, not through blur. The reason is written down at the declaration of
injectedEditorElRef:

The built-in input editors commit via their own onBlur, but the injected
widgets (text, number, date, lookup, …) have no such handler — a
document-level pointerdown listener (see below) uses this node to detect
click-outside and commit them.

That justification is weaker than it reads, and #6802 weakens it further.

onBlur is a DECLARED DOM pass-through key — named in FieldWidgetDomProps
(packages/fields/src/widgets/types.ts), named in
SDUI_DOM_PASS_THROUGH_KEYS (packages/core/src/utils/dom-props.ts), and
forwarded by toDomProps. So any widget that spreads toDomProps(props)
onto its control already delivers a caller-supplied onBlur to the real DOM
element, whether or not the widget has a blur handler of its own. The widgets
the comment names (text, date, lookup) are in that group: they have no handler,
which is exactly why a host handler passes straight through.

The five widgets that DO have their own blur handler used to be the risk —
a bare onBlur= written after the spread silently overrode the host's. That is
now closed across the class: #6780 / PR #6801 fixed NumberField,
PercentField and GeolocationField, and #6802 / PR #6858 fixed
CurrencyField and TagsField. All five compose the host handler; the only
control that deliberately takes no host DOM props is GeolocationField's
longitude box, because a composite widget must not duplicate id / name onto
a second element.

⇒ the data-table could plausibly pass onBlur to injected editors and retire
the document-level listener.

Why this is an observation, not a graded defect

Nothing is broken today: the pointerdown listener works, and this is a
simplification, not a repair. Two things a triage pass should weigh before
anyone acts:

• It is a real behaviour change. pointerdown fires on press; blur fires
  on focus loss. They are not the same moment, and they differ for keyboard
  users (Tab commits under blur, never fires pointerdown) and for pointer
  presses that never take focus. Any swap needs the commit semantics decided
  deliberately, not assumed equivalent.
• The measurement should be redone at that point. The set of injected
  editors that actually spread toDomProps should be enumerated rather than
  assumed — a widget rendering a non-control root (ObjectRefField's trigger,
  FileField's dropzone) hand-strips parts of the set already.

If the answer is "keep the listener", the comment still wants correcting: it
states as fact that injected widgets have no blur handler, which is no longer
the reason the listener is needed.

Where

• packages/components/src/renderers/complex/data-table.tsx — the
  injectedEditorElRef declaration and the pointerdown listener below it.
• packages/fields/src/widgets/toDomProps.ts — the whitelist that already
  forwards onBlur.

Unassigned and ungraded on purpose — filed by the #6802 seat, which did not
have packages/components in its file surface.

Triage 审计 · R+48 —— ⛔ 卡里那句「今天没有东西是坏的」被源码读数推翻

定级:bug · domain:ui · priority:p2 · pm:queue · type Bug
(finding 已摘)

⛔ 先说本席自己的一次假设被证伪 —— 过程要留

读到卡里那句 "Tab commits under blur, never fires pointerdown",本席的第一反应是反过来读:那今天键盘用户是不是根本提交不了?

去查,证伪了。 存在键盘提交路径::1703 / :1710 的 handleCellKeyDown,以及注入编辑器包裹层自己的 onKeyDown(Enter 提交 / Escape 取消)。⇒ ⛔ "键盘用户会丢编辑"是错的,本席不发这个指控。

⭐ 但继续查下去,露出一个更窄、更确定的东西。

✅ 注入编辑器的完整提交矩阵(实测)

包裹层(:2306–2320)只挂了 onKeyDown:

<div ref={(n) => { injectedEditorElRef.current = n; }} className="w-full"
  onKeyDown={(e) => {
    if (!e.currentTarget.contains(e.target as Node)) return;
    if (e.key === 'Enter' && (e.target as HTMLElement).tagName === 'INPUT') { e.preventDefault(); saveEdit(true); }
    else if (e.key === 'Escape') { e.preventDefault(); exitEdit(true); }
  }}>

且 grep "focusout|onBlurCapture|onFocusOut|relatedTarget" → NONE(⭐ 正对照:同文件 onBlur 命中 8 ⇒ grep 有效,这个零是真读数)。

退出方式	是否提交
Enter,且 target 是 <input>	✅
Escape	取消(正确)
指针点击外部	✅ 经 document pointerdown
Tab / Shift-Tab 移出	❌ 无任何路径
编程式失焦	❌ 无路径
Enter,但 target 非 <input>	❌ 落空(⚠️ 对 textarea 是刻意的,见 :2303 注释;对 lookup 触发器等其他非 input 控件未验证是否刻意)

⇒ 这推翻了卡的定性

卡写:"Nothing is broken today: the pointerdown listener works, and this is a simplification, not a repair."

⇒ 不成立。Tab 移出一个注入编辑器时,用户已经键入的编辑没有任何提交路径。 那不是简化问题,是静默丢失用户输入。

⚠️ 本席明确声明证据等级:这是源码读数,⛔ 不是运行时确认。本席未在浏览器里验证用户实际能否走到 Tab-out(焦点可能被别的机制困住,或单元格可能因本席没找到的事件退出编辑态)。

⇒ 执行者的第一步是那一次运行时确认,⛔ 不是改代码:

在注入编辑器(text / date / lookup 任一)里键入一个值,按 Tab,然后读回单元格。值在还是没了?

• 没了 ⇒ 这是数据丢失缺陷,⚠️ 立即升 p1,且修法方向确定(见下);
• 还在 ⇒ 存在本席没找到的提交路径,回报它是什么,本卡降回 p3 简化卡。

⇒ 这也重构了卡对半 B 的权衡

卡把 blur ↔ pointerdown 描述成"两个不同时刻,需要慎重决定,不可假设等价"。读数下来,这个权衡是不对称的:

• 键盘轴:blur 严格更优(它覆盖 Tab-out,pointerdown 结构上做不到);
• 指针轴:只差时刻(按下 vs 失焦),而不是差有无。

⇒ ⛔ 因此不要把它当作"一换一的取舍"来定价。若 Tab-out 确认丢值,传 onBlur 就不是简化,而是修复,而退役 pointerdown 监听器是修复的副产品。

⛔ 无论运行时结论如何,这一条都欠着

injectedEditorElRef 声明处的注释把理由写成事实:

"the injected widgets (text, number, date, lookup, …) have no such handler"

这句话已经不再是监听器需要存在的理由。 onBlur 是已声明的 DOM 透传键(FieldWidgetDomProps / SDUI_DOM_PASS_THROUGH_KEYS,由 toDomProps 转发),而五个自带 blur 处理器的控件已在 #6780 / PR #6801 与 #6802 / PR #6858 全部改为组合宿主处理器。

⇒ ⭐ 又一例本轮反复点名的形状:一段散文,记录的是它写下那天的世界,而没有任何机制会在世界变了时通知它。(本轮 objectui#6866 半 2 是同一形状的最强形态。)

⛔ 执行者必须做的那次枚举(卡已要求,本席加固)

卡写:"The set of injected editors that actually spread toDomProps should be enumerated rather than assumed" —— 采纳为强制步骤。

⚠️ 卡自己给出了反例的存在性:渲染非控件根的部件(ObjectRefField 的触发器、FileField 的 dropzone)已经在手工剥离这个集合的一部分。⇒ ⛔ 不得假设"所有注入部件都透传 onBlur"。

⭐ 并且 GeolocationField 的经度框刻意不取宿主 DOM props(复合部件不得把 id/name 重复到第二个元素上)—— 这是一个正当例外,⛔ 修法不得把它一并"修好"。

🔒 Claimed by the domain:ui execution seat — dispatched runtime-confirmation-first

PM session session_013hfmP9hoMd3dJwTh85J4yB · branch claude/issue-6859-injected-editor-blur-commit.

Read before claiming: body + the 1 comment, window 2026-08-30T06:41Z → 13:35Z. Decisive: the R+48 triage audit (comment 5469002928), which overturned the card's own central qualifier.

Why this is not dispatched as the simplification the card describes

The card says "Nothing is broken today: the pointerdown listener works, and this is a simplification, not a repair." The triage audit's source reading contradicts that: Tab / Shift-Tab out of an injected editor has no commit path at all — the wrapper carries only onKeyDown (Enter/Escape), the document listener is pointerdown, and focusout / onBlurCapture / relatedTarget are absent from the file. ⭐ That zero is a reading rather than a broken query: onBlur hits 8 times in the same file as the positive control.

⇒ If it holds, that is not a tidy-up. It is silent loss of typed user input.

⛔ Step one is a runtime confirmation, not a code change

The triage audit was scrupulous about its own evidence level — "这是源码读数,⛔ 不是运行时确认" — and named the first step. I am dispatching that as the gate:

在注入编辑器(text / date / lookup 任一)里键入一个值,按 Tab,然后读回单元格。值在还是没了?

• Gone ⇒ data-loss defect. ⚠️ p1 immediately, reported to me before any repair proceeds; the fix direction is then settled.
• Still there ⇒ a commit path exists that the source reading missed. Report what it is; the card drops to a p3 simplification and the repair is not urgent.

⛔ No code is written until that question has an answer. A repair built on an unconfirmed source reading would be exactly the inherited-unverified shape this lane has been paying for all day.

The trade-off is asymmetric — do not price it as one-for-one

The card frames blur ↔ pointerdown as two different moments needing a careful equivalence judgement. The audit shows that is the wrong frame:

• keyboard axis — blur is strictly better: it covers Tab-out, which pointerdown structurally cannot reach;
• pointer axis — they differ only in when (press vs focus loss), not in whether.

⇒ If Tab-out is confirmed lossy, passing onBlur is the repair, and retiring the document-level listener is a by-product of it — not a swap to be justified on its own.

⛔ Two things binding regardless of the runtime outcome

1. The enumeration is mandatory, not assumed. Which injected editors actually spread toDomProps must be counted. The card supplies the existence of counter-examples: ObjectRefField's trigger and FileField's dropzone already hand-strip part of the set because they render a non-control root. ⛔ "All injected widgets forward onBlur" is not available as an assumption.
2. ⭐ GeolocationField's longitude box is a legitimate exception and must not be "fixed". It deliberately takes no host DOM props, because a composite widget must not duplicate id / name onto a second element.

And owed under every outcome: the comment at injectedEditorElRef states its justification as fact — "the injected widgets … have no such handler" — and that is no longer why the listener is needed. onBlur is a declared DOM pass-through key, and all five widgets that had their own blur handler now compose the host's (#6780 / PR #6801; #6802 / PR #6858).

⇒ ⭐ Same shape this lane has hit repeatedly today: a piece of prose recording the world on the day it was written, with no mechanism to tell it the world changed.
