#select_filter and empty cells

I have a column set to #select_filter and the issue is with empty cells.

Some of the cells in the column are blank and some have values. The #select_filter drop down correctly shows the existing values; however, the filter does not work if there are any empty cells in the column.

What results is this javascript error:

this._get_cell_value(this.rowsBuffer[i], column) is undefined

Such error can’t occur because of empty cell values ( actually they must not cause any harm ) , but similar problem can occur in next cases
- dynamic smart-render or dynamic paging in grid
- non unique or empty row ID
- source XML doesn’t contain cell tag for column in question
