Unable to un store event

[stevanicus]

Ext version tested:

• Ext 4.1.1rc2

Browser versions tested against:

• FF14

Description:

• Listen for store load event and then un the created function

Steps to reproduce the problem:

• Create a store in a controller and using the 'on' method - add a listener for the load event to fire
• 'un' the load events function

The result that was expected:

• The 'on' load event calls the function once!

The result that occurs instead:

• the function for on is called everytime the event load is fired

Test Case:

Inside my controller

var store = Ext.create('App.store.MyStore')

store.filter([{  
            property:'id',
            value: myID
        }]); //calls ->Load()<- !

store.on("load", function(a,b,c ...){
                var panel = Ext.create("App.view.myGridPanel");
                this.showInQuickView(panel);
                 this.application.fireEvent("loadDone");
                store.un('load', arguments.callee);                              //doesn't 'un' the event function - even if store is a handedover from the function parameter (in this case = a)
}, this);

When using the refresh button on the pagingtoolbar, the above function is called again. I know that I can add the filters parameter to the store.load({scope, callback, filters}) method... however, then the pagingtoolbar is unaware of the filters at a later stage (i.e. when using the refresh button).

Possible fix:

• add a var i = 0, then stick an if(i==0) inside the above function so the code is only executed once by adding i++ (increment) after the if statement

This isn't a bug. When you remove the event, you also need to pass the scope along.

Also, if you want a single fire event, you can use the single param:

store.on('load', function(){
}, this, {single: true});
