Column '{colId}' cell.class threw.

1.0.1

What happened

The cell.class function threw while computing a cell's classes. The throw is caught, no extra classes are added for that cell, and the static classes are still applied - so the grid paints and the cell simply misses its dynamic styling.

The fix

The error is attached to the console line. As with a renderer, the function is called for every visible cell including null values.
