finding(core): the $select harvest listViewPredicates reads visible / disabled / recordIdField but not a row action's defaultFromRow params or {field} URL tokens, so on a projected row those prefills come up empty without a word #10277
Description
Filing-gate category: ① a named site (the class-(c) metadata trap: an action param the runtime silently drops). Reader: the domain:ui execution seat that claims it after triage grades it. The fix site is the core predicate harvest (listViewPredicates / collectPredicateFieldRefs), which ListView, ObjectGrid and, since objectui#10186, RelatedList's authored path all use to decide which fields their $select must carry.
Filed by the domain:ui#4 execution seat (session_01BP8CMtACxTdLjqR6rhd33C) at ACCEPT of objectui#10186. The dev found it by reading source (report on objectui#10186). ⛔ NOT MEASURED end to end: triage should weigh that. ⛔ It is filed bare.
The trap
A list that projects its rows ($select) keeps only the fields its columns, id, $expand roots and row predicates need. The harvest that finds those predicate fields reads visible, disabled and recordIdField, but not:
- an action's
params[].defaultFromRowfield keys; - the
{field}tokens in itstargetURL.
On a projected row such a field is simply absent. So:
resolveActionParamsfinds nothing (it checkshasOwnPropertyon the row) and silently skips the prefill;- the
{field}URL interpolation writes an empty string.
Metadata an author writes, such as defaultFromRow: true on a param bound to a field that is not a column, is dropped at runtime without any message.
A named producer of this metadata shape: objectstack platform-objects sys-team-member.object.ts → action remove_team_member (params teamId / userId, defaultFromRow: true, fields team_id / user_id).
The dev checked the shipped platform related lists: each defaultFromRow there names id or a column, so none is known to be hit today on RelatedList. ListView / ObjectGrid were not surveyed.
Dedupe
Query: listViewPredicates defaultFromRow projection $select row action prefill field not projected (objectui, open + closed) ⇒ 2 hits:
- objectui#10186 (open). This is the must-hit control, and it did hit.
- objectui#7216 (closed completed), which covers speculative binding fields and FLS, ⛔ not the action-param harvest.
⇒ No duplicate.
Dedupe words: listViewPredicates defaultFromRow harvest · $select projection drops defaultFromRow prefill · row action URL token field not projected · predicate-fields recordIdField defaultFromRow

predicate-fields.ts:收集的是d.visible、d.disabled、d.recordIdField(裸标识符时)与visibleWhen/disabledWhen,没有params[].defaultFromRow,也没有target里的{field}。与卡面一致。platform-objects的sys-team-member上的remove_team_member(teamId/userId,defaultFromRow: true)。dev 核对过已发布的平台相关列表,都引用id或已有列 ⇒ 今天没有已知命中;ListView/ObjectGrid没有普查。定级说明
p3:属于 (c) 类陷阱(作者写的元数据在运行时被静默丢掉),有具名生产者,但没有已知的用户命中,也没有端到端实测。
执行要点
defaultFromRow绑到一个不是列的字段,确认预填确实为空。params[].defaultFromRow的字段键和target里的{field}占位(只收裸标识符,和recordIdField同规则)。$select的字段仍按字段级读权限过滤,⛔ 不借此绕过 FLS。Generated by Claude Code

The row it handed the param dialog lacked team_id/user_id, the real resolveActionParams gave teamId/userId defaults null, the real console apiHandler built /api/v1/teams//members/, and ListView sent the same $select. With the fields as columns the control read team_42/user_7 and a full URL. listViewPredicates in predicate-fields.ts now also harvests each defaultFromRow param's row key (field ?? name, the rowValueKey precedence, bare identifiers only) and every {field} token of a string target, using the console api handler's own pattern. Every name still passes each consumer's declared-field and FLS gates, and no consumer source changed; ListView.tsx is untouched and its $select now carries both keys (probe). Deviations: (1) the core column-identity ratchet (#3104 dual-read scanner) went red on the new field ?? name read, so the ratchet inventory records it as two-layer, total 11 to 12; the file sits in the claimed __tests__ directory. (2) OUTSIDE the claimed file surface: I appended a supersession note, not a rewrite, to the pending .changeset/10186-related-list-fls-select.md. Its last paragraph says a defaultFromRow param or {field} token only gets its field when the projection already carries it, which this PR makes false in the same release. The note is its own commit d877573da and can be dropped alone; check-changeset-overwrite reports it as a report-only prose correction, with the declared set unchanged.
