Experiencing the same issue; seems to be caused by expandDetail and collapseDetail for grids comparing to `undefined` instead of `'undefined'` - see https://github.com/atatanasov/gijgo/blob/01fa532c414c220e1e819c640d32c0cceeb67e2f/src/grid/js/grid.expandCollapseRows.js#L164 and https://github.com/atatanasov/gijgo/blob/01fa532c414c220e1e819c640d32c0cceeb67e2f/src/grid/js/grid.expandCollapseRows.js#L182
