Change Template in List? (v2.1)

[Stx.Greg]

I'm trying to extend the new List component in Sencha Touch 2.1 (I'm using RC2) and I can't seem to change the item template dynamically. I'd like to be able to change item templates by pressing a button, but it won't work. It used to work in version 2.0.1. Is there anything I'm missing?

Calling setItemTpl() works in the initialize method, but not in edit() or editCompleted() methods.

Here is the test code I have using.

    Ext.application({
        name: 'SenchaTest',
        launch: function () {


            var app = this;


            Ext.define('TestModel', {
                extend: 'Ext.data.Model',
                config: {
                    fields: [
                        {name: 'field1'},
                        {name: 'field2'},
                        {name: 'field3'},
                    ]
                }
            });


            Ext.define('Stx.dataview.MyList', {
                extend: 'Ext.dataview.List',


                config: {
                    normalTpl: null,
                    editTpl: null,
                    editing: false,
                    scrollToTopOnRefresh: false,
                },


                initialize: function () {
                    this.callParent();
                    this.setItemTpl(this.getNormalTpl());
                },


                edit: function () {
                    if (!this.getEditing()) {
                        this.setEditing(true);
                        this.setItemTpl(this.getEditTpl());
                    }
                },


                editCompleted: function () {
                    if (this.getEditing()) {
                        this.setEditing(false);
                        this.setItemTpl(this.getNormalTpl());
                    }
                },
            });


            this.store = Ext.create("Ext.data.Store", {
                model: 'TestModel',
                data: [
                    {field1: "data1Field1", field2: "data1Field2", field3: "data1Field3"},
                    {field1: "data2Field1", field2: "data2Field2", field3: "data2Field3"},
                    {field1: "data3Field1", field2: "data3Field2", field3: "data3Field3"},
                    {field1: "data4Field1", field2: "data4Field2", field3: "data4Field3"},
                    {field1: "data5Field1", field2: "data5Field2", field3: "data5Field3"},
                    {field1: "data6Field1", field2: "data6Field2", field3: "data6Field3"},
                    {field1: "data7Field1", field2: "data7Field2", field3: "data7Field3"},
                    {field1: "data8Field1", field2: "data8Field2", field3: "data8Field3"},
                    {field1: "data9Field1", field2: "data9Field2", field3: "data9Field3"},
                    {field1: "data10Field1", field2: "data10Field2", field3: "data10Field3"},

                    {field1: "data12Field1", field2: "data12Field2", field3: "data12Field3"},
                    {field1: "data13Field1", field2: "data13Field2", field3: "data13Field3"},
                    {field1: "data14Field1", field2: "data14Field2", field3: "data14Field3"},
                    {field1: "data15Field1", field2: "data15Field2", field3: "data15Field3"},
                ]
            });


            this.button = Ext.create("Ext.Button", {
                text: "Edit List",
                listeners: {
                    tap: function () {
                        if(!app.list.getEditing()) {
                            app.list.edit();
                        } else {
                            app.list.editCompleted();
                        }
                    }
                }
            });


            this.normalTpl = Ext.create("Ext.XTemplate",

Did you try executing refresh method on the list?

[vitalyx]

Hi,

I have the very same issue.

When using setItemTpl on a list from controller, the list shows empty items. Calling list.refresh() makes no effect.
But when assigning itemTpl in the view, the list does render the items.
There was no such behavior in Sencha Touch 2.0.1.

I may have just run into this issue myself. Unless any of you have a simple test case then I will have to take the time to create one today some time.

Did you try executing refresh method on the list?

Yes, and it didn't work. I forgot to include the refresh statement in my example code, but calling refresh() after calling setItemTpl() has no effect.

Is my test code not sufficient? It is just a bare-bones app to demonstrate the problem.

It can be simplified:

var store = new Ext.data.Store({
    fields : ['test', 'test2'],
    data   : [
        {
            test  : 'One',
            test2 : 1
        },
        {
            test  : 'Two',
            test2 : 2
        },
        {
            test  : 'Three',
            test2 : 3
        },
        {
            test  : 'Four',
            test2 : 4
        },
        {
            test  : 'Five',
            test2 : 5
        }
    ]
});

Ext.Viewport.add([
    {
        xtype  : 'toolbar',
        docked : 'top',
        items  : [
            {
                text    : 'Change itemTpl',
                handler : function() {
                    var list = Ext.Viewport.child('list');

                    list.setItemTpl('{test2}');
                }
            }
        ]
    },
    {
        xtype   : 'list',
        itemTpl : '{test}',
        store   : store
    }
]);

I have opened a bug for this.

[vitalyx]

Thanks. Any ETA for Sencha Touch 2.1.1? This is kind of a major bug for any non-trivial real-life project. We are eager to switch to Sencha Touch 2.1 for performance improvements alone, but can't do this because of this bug.

[mitchellsimoens]

There is no public dates but patch releases do come out frequently
