Repeated to open web page after pollProvider

[volcom721]

Hello sencha:
I has a problem here. In normal, if i execute function1 and browser will open the web page "test1.html" once. But if i add a poll provider like execute function2, and then execute function1 after function2 finish, browser will open the web page "test1.html" twice. If i execute function2 tree time then execute function1, the browser will open the web page tree time. Why happen this? is there has some parameter i am not setting? or i didn't close the provider correct? please help me, i am so confused here, thanks.

#Function1:
    window.open('../web/test1.html');

#Function2:
        Ext.direct.Manager.addProvider({
            type:'polling',
            url: '../Svr.php',
            interval: 3000,
            id: "provider1",
            baseParams:{ 'func':'homeMgr', 'op':'getProcessStatus', 'proId': 'provider1'  },
            listeners: {
                data: function(provider, event){
                    var proResult = event.proResult;
                    if( proResult == "finish" ){
                        Ext.direct.Manager.getProvider( proId ).disconnect();
                        Ext.direct.Manager.removeProvider( proId );
                        Ext.getCmp(pbWinvId).close();
                    }
                }
            }
        });

I just know why happen this problem, because i execute init() before add provider, like this:

var homeCol = me.getController('home.HomeCol');
homeCol.init();

So every time i execute it, browser will open web page more once.
But why? i was read the document, but i still don't know why?
