Multiple Ext.data.Store extended class but juste one model?

[newmind@free.fr]

Hello,
I create a class that extends ext.data.store. I create two other classes that extend the first. Oddly the two derived classes share thesame model :

Class 1 (Mother) :

Ext.define('Appli.store.GridFilter',{
    extend:'Ext.data.Store',
    proxy : {
            actionMethods :{
                read:'post'
            },
            type:'rest',
            reader : {
                type: 'json',
                root: 'rows'
            }
         },


    
     constructor: function(config) {


        this.callParent([config])
        return this;
     }
    
});

Class 2 :

Ext.define('Di.store.logExec.GridFilter',{
    extend:'Appli.store.GridFilter',
    model: 'Di.model.logExec.GridFilter',
    constructor:function(config){
        this.proxy.url = '/di/LogExecFindGrid/read/';
        this.callParent(arguments);
        return this;
    }
    
});

Class 3 :

Ext.define('Di.store.tache.GridFilter',{
    extend:'Appli.store.GridFilter',
    model:'Di.model.tache.GridFilter',
    constructor:function(config){
        this.proxy.url ='/di/TacheFindGrid/read/';
        this.callParent(arguments);
         return this;
    }
});

If I use the config property, then it works :

Class 1 (Mother) :

Ext.define('Appli.store.GridFilter',{
    extend:'Ext.data.Store',
    config:{
        proxy:{
            actionMethods :{
            read:'post'
            },
        type:'rest',
        reader: {
                type: 'json',
                root: 'rows'
            }
        }
    },
     constructor: function(config) {
         this.initConfig(config);
        this.callParent([config])
         return this;
     }
    
});

class 2 :

Ext.define('Di.store.logExec.GridFilter',{
    extend:'Appli.store.GridFilter',
    config:{
        model:'Di.model.logExec.GridFilter',
        proxy:{
            url :'/di/LogExecFindGrid/read/'
        }
    }
});

Class 3 :

Ext.define('Di.store.tache.GridFilter',{
    extend:'Appli.store.GridFilter',
    config:{
        model:'Di.model.tache.GridFilter',
        proxy:{
            url :'/di/TacheFindGrid/read/'
        }
    }
    


});

Can you help me?

What makes you think that they share the same model?
