HTML Widgets; Grid control; Sortable grids with checkbox column were not working correctly and may have selected the incorrect item

HTML Widget grids that are sortable AND have a checkbox column, e.g., the Documents Publish wizard, were not working correctly if a column was sorted.

The e.row.listIndex parameter was incorrect when passed to the BeforeCellUpdate event handler. Other, non-checkbox controls such as lists and number boxes were correct.
