Ext.clone a store

[Webtel]

i have a store_A and i want to have one more, similar to this (model,proxy) but loaded independent.

when i do it like : (ExtJS 4.07)

store_B = Ext.clone(store_A);

and then :

store_A.load();
store_B.removeAll();

... both are empty in the end (like they were one object - but documentation says reference should be dropped by Ext.clone.. )

Is it a bug? or am i doing something wrong?

Is it obligatory to define whole new store separately just for having 2 data sets of same model and source?

PS. following makes no difference.

var store_B = Ext.apply({},store_A);

to achieve store cloning i use function similar to following:

clone = function(dict){
	return Ext.create(dict.$className,{
		proxy:{
			url:dict.proxy.url,
			type: 'ajax',
			extraParams:dict.proxy.extraParams,
			simpleSortMode : true,
			reader: {
				type: 'json',
				root: 'rows',
				totalProperty:'total',
				successProperty: 'success',
				idProperty:dict.proxy.reader.idProperty
			}
		}
	});
}

or maybe just :

Ext.define('definedStore', {...});
storeA = Ext.create('definedStore');
storeB = Ext.create('definedStore');

Clone is only intended to be used on "primitive" type objects, data stores have a whole bunch of complexity that mean they can't really be cloned in a generic manner.

@chramer
actualy i have one generic store class for all combos. then i create instances of particular lists only chainging proxy extra params.

so i need a copy of already created store because :
- i dont want to rewrite each proxy by hand
- and also i dont want to have 200 separate store class definitions.(for readability sake)

going Your way leads to deifining 200 classes only differing with one extraParam (wile i need just one). Plus 300 instantiations.

The other way is like 1 class definition. Plus 200 instantiations. Plus 100 cloning.
