column in grid columnModel won't hide

[Bobafart]

I am trying to create a hidden column in my grid columnModel:



var cm = new Ext.grid.ColumnModel([
{header: "SoldierID", isHidden: true, dataIndex: 'troopId'},


with that code the column "SoldierID" remains visible -- although there is no data in the cells.

How do you make the column totally hidden?

The config entry is 'hidden', not 'isHidden'
