Warnings reference › fullWidth.render.missing

Identifier

fullWidth.render.missing

Raised by

The grid (rendering)

Since

1.6.0

What happened

Half of the full-width row feature was configured. Rendering an empty band where a full-width row should be would look like a layout defect and be reported as one, so the whole feature is refused instead and every row renders as an ordinary row.

The fix

Supply render(params) alongside when(row).

The smallest fix

fullWidth: { when: (row) => row.data.kind === 'note', render: (p) => p.row.data.text }
