    Answered: How to correctly replace the contents of a list?


    I have a panel with a list view. In the panel's activate event I set the list view's data like so:
    Code:
                    activate: function() {
                        var me = this;
                        Ext.Ajax.request({
                            url: 'data/sites.json',
                            success: function(response) {
                                me.child('list').setData(JSON.parse(response.responseText));
                            }
                        })
                    }
    This works as expected. However, I've added the panel to a navigation view and if I pop back to this panel, the activate event is fired again. This has the rather strange effect, that the list gets additional entries. I would have guessed that setting the data property will replace the current entries, not add them.

    Is this a bug in Sencha Touch 2.0 beta 3 or am I don't something wrong here?

    Each time, I push and pop another panel on top of this panel, the list gets longer.

  2. Looking into the source, the intended behavior is indeed to add the data, not to replace it. I'm now using a Ext.data.Store instance to wrap my data and it works.

    You should really be adding/removing data from the store not the list.
