Hi!

Code:
var cmlen = grid.getView().getHeaderCt().getColumnCount();
                for (i = 0; i < cmlen; i++) {
                    var col = column = grid.getView().getHeaderCt().items.getAt(i);
}
I'm rewritting GridPanel plugin from ExtJs 3 to ExtJs 4.

WHY THE HELL THERE IS NO DOCUMENTATION FOR THIS??????????????????

no property headerCt, no method getHeaderCt():

http://docs.sencha.com/ext-js/4-0/#!/api/Ext.grid.View
http://docs.sencha.com/ext-js/4-0/#!/api/Ext.grid.Panel
http://docs.sencha.com/ext-js/4-0/#!/api/Ext.view.View

I'm totally angry right now. We have bought commercial license, I read have read all the migration posts about getHeaderCt(), but I can't find it in doc.

Please respond as soon as possible.

Thanks!
