Gelmiş geçmiş en büyük porno sitemiz olan 2pe de her zaman en kaliteli pornoları sunmayı hedefledik. Diğer video sitemiz olan vuam da ise hd porno ağırlıklı çalışmalara başladık.

    Looks like we can't reproduce the issue or there's a problem in the test case provided.

    Default Unable to un store event

    Unable to un store event


    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
    Code:
    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:

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