    Default Scrolling to on scrollend

    Scrolling to on scrollend


    Hi everyone,

    What I want is simple but I can't make it work. I have an Ext.List with 5 items in it. When I scroll to the end of that list, it load 5 more items and so on. After loading these new items, I want to scroll down to these news items.

    I tried the next code but it does not work. The alert return 0.
    But then, when I scroll the list again (not even to the end) it scrolls to these news items.

    Code:
    this.actuGrid = new Ext.List({
        	store: app.stores.actualites,
            grouped : false,
            itemTpl: app.templates.actualiteList,
            listeners: {
                scroller: {
                    scrollend: function(scroller, offset){                  
                        var currentNumberOfNews = parseInt(app.stores.actualites.getCount());
                        var nextNumberOfNews = currentNumberOfNews+app.newsPerLoad;
                        var newYPosition = currentNumberOfNews*70;
                        app.stores.actualites.load(
                            new Ext.data.Operation({
                                start:0,
                                limit:nextNumberOfNews
                            })
                        );
                        scroller.scrollTo({x:0,y:newYPosition});
                        alert(offset.y);
    
                    }
                }
            }
        });
    I hope somebody can tell me what is wrong with the code or what the problem is.

    Thank you

    Have you tried just using the ListPagingPlugin that is included in the framework?

    No, I didn't try it yet because I wanted to use my own code. Plus I don't see what I'm doing wrong here, and I would like to understand why it doesn't work and not 'skip the problem'.

    But if nobody finds out what the problem is here, I'll give it a shot.

    Thanks
