Pull request overview
This PR fixes a Next.js SSR build failure by making the useDataScope hook context-optional, allowing components to render during static generation without throwing errors when SchemaRendererProvider is absent.
Changes:
- Modified
useDataScopeto returnundefinedinstead of throwing when context is missing - Enhanced
SimpleTableRendererto support inline data fallback and flexible column property names for backwards compatibility

The new inline data fallback behavior lacks test coverage. The repository has comprehensive automated testing for other components (see packages/components/src/__tests__/layout-data-renderers.test.tsx), but there are no tests for the SimpleTableRenderer or the new data fallback chain.
Tests should verify:
- Data binding via
useDataScopewhen context is available - Fallback to
schema.datawhen no binding exists - Fallback to
schema.props?.dataas a third option - Graceful handling when
useDataScopereturnsundefined(SSR scenario) - The new column property aliases (
key/accessorKey,label/header)
This is especially important for SSR scenarios which are harder to debug in production.

The behavioral change to make useDataScope context-optional lacks test coverage. While the change fixes SSR issues, there are no tests verifying:
- The hook returns
undefinedwhen context is missing (new behavior) - The hook still works correctly when context is available
- Path resolution works correctly with the optional context
- Edge case: what happens when context exists but
dataSourceisundefined
The repository has test infrastructure (packages/react/src/__tests__/) but no coverage for this critical hook. This is a significant behavioral change that should be tested to prevent regressions.

There's a potential edge case issue with the guard condition. When !dataSource is true (context is missing or dataSource is explicitly undefined/null/empty), the function returns dataSource which could be undefined. However, when !path is true but dataSource exists, it also returns dataSource.
This conflates two different scenarios:
- Context missing → should return
undefined - No path provided → should return the full dataSource
Consider separating these cases for clarity:
if (!dataSource) return undefined;
if (!path) return dataSource;This makes the intent clearer and ensures consistent behavior.
| if (!dataSource || !path) return dataSource; | |
| if (!dataSource) return undefined; | |
| if (!path) return dataSource; |

| <TableHead key={col.key || col.accessorKey || index}> | ||
| {col.label || col.header} | ||
| </TableHead> |

According to Rule #0 of the coding guidelines, all component schemas must strictly follow definitions in @objectstack/spec. The standard TableColumn interface (defined in packages/types/src/data-display.ts:203-260) uses header and accessorKey as the canonical property names, not label and key.
While adding fallback support for key/label provides backwards compatibility, this creates ambiguity and deviates from the spec. The documentation at content/docs/components/complex/table.mdx:14-20 and examples in packages/components/src/stories-json/data-table.stories.tsx:21-24 consistently use header and accessorKey.
Consider either:
- Removing the
key/labelaliases and only supporting the spec-compliantaccessorKey/headerproperties, or - Documenting this deviation from the spec with a clear migration path if these are legacy properties being phased out.

| const accessor = col.key || col.accessorKey || ''; | ||
| const value = accessor ? row[accessor] : ''; | ||
| return ( | ||

| {value} | ||
| </TableCell> | ||
| ); | ||

According to Rule #0 of the coding guidelines, all component schemas must strictly follow definitions in @objectstack/spec. The standard TableColumn interface uses accessorKey and header as the canonical property names, not key and label.
The fallback to col.key and col.accessorKey creates ambiguity. The code should consistently use the spec-compliant property names. Consider removing support for the non-standard key property or documenting why this deviation from the spec is necessary.

According to Rule #2 (Documentation Driven Development) of the coding guidelines, the task is not complete until the documentation reflects the new code/architecture.
This PR introduces significant behavioral changes:
useDataScopenow returnsundefinedinstead of throwing when context is missing- Table component supports inline data via
schema.dataorschema.props.data
These changes should be documented in:
packages/react/README.mdor equivalent documentation for theuseDataScopehook behavior changecontent/docs/components/complex/table.mdxto show the inline data usage pattern for SSR scenarios
The documentation currently shows examples using only the data property directly on the schema, but doesn't explain the context-optional behavior or the fallback chain (boundData || schema.data || schema.props?.data).
| // Try to get data from binding first, then fall back to inline data | ||

| const data = boundData || schema.data || schema.props?.data || []; | ||
| const columns = schema.columns || schema.props?.columns || []; |

The component supports multiple ways to specify columns (schema.columns vs schema.props?.columns), which creates ambiguity. According to the @objectstack/spec protocol, component properties should follow a consistent structure.
Looking at the ObjectGrid implementation (packages/plugin-grid/src/ObjectGrid.tsx:174), columns are accessed via schema.columns, not schema.props.columns. The SchemaRenderer passes schema properties both as direct props and under schema.props, but the standard pattern appears to be accessing them directly from the schema object.
Consider standardizing on schema.columns only, or document why both paths are necessary.

| const columns = schema.columns ?? []; |

Next.js build failing on
/docs/components/complex/tableduring static generation becauseuseDataScopeunconditionally throws whenSchemaRendererProvideris absent.Changes
useDataScopehook: Returnundefinedinstead of throwing when context is missing. Added guard to prevent reduce operation on undefined dataSource.SimpleTableRenderer: Support inline data fallback (schema.data,schema.props.data) when no binding exists. Accept bothaccessorKey/keyandheader/labelcolumn properties for API flexibility.This preserves data binding functionality while enabling components to render during static generation with inline data.
