Description

In gridApi.edit.on.afterCellEdit(), I update a row property used by columnDef.cellClass(). This is used for visually displaying validation. When cellClass() executes, it is operating on an old version of the row object. $scope.apply() does not seem to execute columnDef.cellClass() again. It would be wonderful if there was a way to trigger columnDef.cellClass() for a cell, row, or the entire grid.

Reproduction Steps: Edit a cell, click away, the cell class is not applied because the row object has not been updated when columnDef.cellClass() runs.

Research direction
Investigate the sequence of events in the grid API after a cell edit, specifically the timing of the row model update compared to cellClass evaluation. Look into the grid's internal refreshCell or refreshRow methods that could be used to trigger a re evaluation of cellClass. The issue comments may contain further discussion on workarounds or desired API changes.
