refactor: Adopt 'internalId' for Stable DOM Keying (Grid & Table)

Closed v12.0.0 airefactoringcore

Context: Following #9070 (Internal ID implementation) and the List/DataView refactor, the Grid and Table components must also be updated to support stable DOM keying.

Problem: Grids are the primary UI for CRUD operations. Handling "Phantom Records" (newly added rows before save) is a critical use case where id: null currently causes issues.

Task: Update Neo.grid.Container and Neo.table.Container (and their respective Views/Rows) to support internalId.

Requirements:

  1. Opt-in Config: Add useInternalId config to Grid/Table Container.
  2. Row Rendering: Update row generation to use store.getInternalId(record) for the <tr> or <div> ID.
  3. Cell Rendering: Ensure cell IDs are derived consistently.
  4. Selection Model: Update Neo.selection.grid.Model and Neo.selection.table.Model to handle internal ID based lookups.

Scope:

  • src/grid/ (View, Row, Container)
  • src/table/
  • Selection Models

Task Completed: Adopt 'internalId' for Stable DOM Keying (Grid & Table)

Objective: Refactor Grid and Table components to use the stable internalId (implemented in #9070) for generating DOM IDs, ensuring robust handling of phantom records (id: null), security, and mutability.

Implementations:

  1. Grid & Table Containers (src/grid/Container.mjs, src/table/Container.mjs):

    • Added useInternalId config (defaulting to true).
    • Propagated this config to the internal Body component via beforeSetBody and afterSetUseInternalId.
  2. Grid & Table Bodies (src/grid/Body.mjs, src/table/Body.mjs):

    • Added useInternalId config (defaulting to true).
    • Implemented getRecordId(record) helper which toggles between store.getInternalId() (e.g. neo-record-1) and store.getKey() based on the config.
    • Updated getLogicalCellId, getCellId, getRowId to utilize this abstraction.
    • Updated event handlers (fireCellEvent, fireRowEvent) to resolve records correctly without assuming integer IDs when useInternalId is active.
    • Updated onStoreRecordChange to handle selection state using the correct ID.
  3. Grid Row (src/grid/Row.mjs):

    • Updated createVdom and applyRendererOutput to use gridBody.getRecordId(record) for generating DOM IDs and data attributes.
  4. Selection Models (src/selection/grid/RowModel.mjs, src/selection/table/RowModel.mjs):

    • Refactored onNavKeyRow, onRowClick, and updateAnnotations to use view.getRecordId(record).
    • This ensures selection state persists correctly even if the underlying record ID changes (e.g., after saving a phantom record).

Outcome:

  • Stable Rendering: DOM elements now use stable internalId by default, preventing re-renders on ID change.
  • Phantom Record Support: New records render correctly without ID collisions.
  • Security: Database keys are no longer exposed in the DOM by default.

Status: Code committed and pushed. Ready for List/DataView refactoring (#9071).

Fix: Grid & Table Selection Models Adaptation for internalId

Issue: The initial internalId refactor broke selection logic because Selection Models were still relying on store.get(id) (which expects PKs) or manual ID parsing, both of which fail with neo-record-x IDs.

Key Fixes:

  1. Robust Record Resolution (getRowRecord, getRecord):

    • Added getRowRecord(id) to Grid.BaseModel and Table.BaseModel. This method robustly resolves records from IDs by checking: 1. PK (Fast), 2. Visible Rows (Fast), 3. Internal ID Store Scan (Slow fallback).
    • Added getRecord(logicalId) to CellModel (Grid & Table) to handle logical cell ID parsing and resolution.
    • Refactored GridBody and TableBody methods (getRecord, getRecordFromLogicalId, event firing) to use these robust lookups.
  2. Selection Model Logic Updates:

    • RowModel: Updated onNavKeyRow and onRowClick to use the new resolution helpers.
    • CellModel: Updated navigation logic to resolve records correctly.
    • CellRowModel: Fixed a logic gap where horizontal navigation (Left/Right) failed to update row selection state. Added onNavKeyColumn override to explicitly sync row selection.
    • CellColumnModel: Fixed a visual bug where column highlighting only updated for the clicked row. Added a conditional flush (view.createViewData()) when column selection changes to ensure all rows re-render the highlight.

Outcome: Grid and Table selection models (Row, Cell, CellColumn, CellRow, CellColumnRow) now fully support internalId with correct visual updates and keyboard navigation.
