Hi there,

When i try to manipulate with cell in a row, all of sudden I'm getting following error:

Failed with error e.getHeaderContainer(...).getColumns is not a function.
Previously worked alright, but all of sudden I'm getting that error.
Funciton which I'm executing contains calls cellAt method. without cellAt row can be ".visible()"

ST.grid('#dataDatatableID', 50000).rowAt(0, 50000).cellAt(0, 50000).down('>> .x-action-col-icon').click();
