looking for best practice dealing with empty Jsonstore

[wilderland]

Hello,

I hope you can help me, i digged in the forum and the tutorial, but i didn't found a good example how I deal with a empty Json-Store.

I my case I would like to react on a failure a the server, also the JSON brings his metadata for the store from the server. I set the successProperty. But at the moment I have to deal with the success by my own. How I read it is possible that the JSON-Store will react on this. Maybe I have some problems in the configuration or in understanding how it work.

here the JSON-Stream

{
    "success": false,
    "errors": {
        "errornumber": 403,
        "errormessage": "Zugriff nicht erlaubt"
    },
    "metaData": {
        "totalProperty": "resultcount",
        "root": "Activities",
        "successProperty": "success",
        "message": "errors",
        "fields": [ 
			{"name": "Activity.id"}, 
			{"name": "Activity.user_id"}, .. some more fields ..
        ]
    },
    "resultcount": 0,
    "Activities": [
        
    ]
}

here the Class with deals with the JSON-Data

ActivityList =function(config){
	this.StoreActivityList = new Ext.data.JsonStore({
		autoLoad : true,
		url : webRoot+'dashboard/activitylist.json',
		listeners:{loadexception:function(a,request,response,error){
				if(error instanceof Error) {
              		var msg = "Error while processing server response: "+error.name+": "+error.message;
              		Ext.Msg.alert('Fehler',msg);
            	}else{
            		alert(response);
            	}
			},
			load: function(store, records, options){
				 var data = store.reader.jsonData;
				  if(!data.success){
				      alert(data.errors.errormessage);
				  }
			}
		}
	});
	
	var preConfig = {
		store: this.StoreActivityList ,
		viewConfig: {
			forceFit: false
		},
		sm: new Ext.grid.RowSelectionModel({singleSelect:false}),
		frame:true,
		title:'aktuelle Alarme',
		iconCls:'icon-grid',
		region:'center',
	};
	
	//config um fehlende Werte erweitern 	
	if (config != null){
		Ext.applyIf(config,preConfig);
	}else{
		config = preConfig;
	}
	
	ActivityList.superclass.constructor.call(this, config);
};

Ext.extend(ActivityList, Ext.grid.GridPanel, {
	info: function(){
		//
	}
});

My Question is: Why does the Store not react on success:false and how can I stop the processing in load-event?

Thanks
