header-name:*:*

Raised by

The grid (rendering)

Since

1.4.0

What happened

A column or column group named a header renderer by name and nothing is registered under it, so no custom header is used and the stock heading is drawn.

The fix

Register the component in config.components, or pass the function directly.

The smallest fix

createGrid(el, { components: { unitHeader: renderUnitHeader }, columns: [{ id: 'qty', header: { render: 'unitHeader' } }] });
