Fix duplicate data in calendar and board

[Copilot]

Fixes a bug where Calendar and Kanban views displayed every record twice.

Root Cause

When renderListView is provided (console app path), PluginObjectView was unconditionally fetching data in its own useEffect, even though the ListView (created by renderListView) independently fetches the same data. This caused:

1. Two parallel fetch requests to the same endpoint
2. PluginObjectView's state updates (setData, setLoading) triggering unnecessary re-renders
3. These re-renders destabilizing the child component rendering pipeline, leading to duplicate records in Calendar and Kanban views

Additionally, ObjectKanban lacked proper external-data handling — it used fragile (props as any).data casting instead of explicit typed props, and didn't properly sync parent loading state changes.

Changes Made

Fix 1: packages/plugin-view/src/ObjectView.tsx

Skip PluginObjectView's data fetch when renderListView is provided, since the custom list view (e.g. ListView) handles its own data fetching.

Fix 2: packages/plugin-list/src/ListView.tsx

Added missing results.value (OData format) handling to the data extraction logic, consistent with extractRecords utility used elsewhere in the codebase.

Fix 3: packages/plugin-kanban/src/ObjectKanban.tsx

Added explicit data?: any[] and loading?: boolean props to ObjectKanbanProps interface. Implemented hasExternalData guard pattern (matching ObjectCalendar) that:

• Detects when parent provides pre-fetched data via props
• Skips internal dataSource.find() when external data is present
• Syncs parent loading state changes via useEffect
• Replaces fragile (props as any).data with typed destructured props

Regression Tests

• DuplicateData.test.tsx: 3 tests verifying Calendar and Kanban views each render records exactly once (no duplicates), including wrapped response format
• DataFetch.test.tsx: 1 new test for { value: [] } OData response format extraction

CHANGELOG.md

Updated with comprehensive description of all fixes.

All remaining work items are now complete in commit af7a4a0:

Fix 3 — ObjectKanban external data handling: Added explicit data?: any[] and loading?: boolean props with hasExternalData guard pattern (matching ObjectCalendar). This replaces the fragile (props as any).data casting, properly skips internal fetch when parent provides data, and syncs loading state changes.

Regression tests: 4 new tests passing:

• Calendar: no duplicate events (plain array + wrapped response format)
• Kanban: no duplicate cards
• ListView: OData { value: [] } extraction

CHANGELOG.md updated.

All 148+ existing tests continue to pass (128 kanban, 7 data fetch, 2 calendar nested config, 4 view switching, etc.).

Pull request overview

This PR fixes duplicate record rendering in Calendar and Kanban views by eliminating unintended parallel data fetches when a custom renderListView is used (console path), and by improving consistency of record extraction across response shapes.

Changes:

• Prevent @object-ui/plugin-view’s ObjectView from fetching its own data when renderListView is provided (avoids duplicate requests / re-render churn).
• Extend @object-ui/plugin-list’s ListView to extract records from OData-style { value: [...] } responses and add a regression test.
• Update @object-ui/plugin-kanban’s ObjectKanban to accept external data/loading props and skip internal fetching when external data is supplied; add console regression tests and update the changelog.

...props is no longer used after removing the (props as any).data access. Consider removing the rest destructuring to avoid keeping an unused binding and to make it clear which props are supported/passed through.

Suggested change

...props

[Copilot]

This useEffect updates the local loading state from the new loading prop, but loading is never used in the render output (not passed into KanbanRenderer and no loading UI is shown). Either wire loading through to the kanban renderer / show a loading skeleton/overlay, or remove the unused state+prop to avoid dead code.
