I have a grid with a column where NumberField is used for an editor. I have following general configuration to set comma as a separator instead of a dot:

Ext.override(Ext.form.NumberField, {

When NumberField is used on forms I have comma as a separator, but in a grid a dot is displayed. On submit in a grid a value with a dot is submitted.

On form value with a comma is submitted.

Where should I set that grid would also send a coma instead of a dot.
