javascript - Ext.Create and this.callParent -

-

how can use ext.create , this.callparent together? if use following code errors retrieving data ajax store.

items: [     { xtype: 'combo',         initcomponent: function() {             ...             this.callparent(arguments);         }     } ]

any suggestions?

the callparent docs say:

call "parent" method of current method. method overridden derivation or override (see ext.define).

in other words, callparent within ext.define or ext.override; not when override method in config.

what important understand initcomponent not meant overridden config. should extend combo class , override initcomponent there.
