Updating Child Panels in Sencha Touch MVC App

Developing a Sencha Touch MVC app that pulls data from json store (thats set up to a DB pulling out content from a Wordpress Blog).

Everything works up until my "detail" panel. Instead of it listening to the TPL, its just dumping some data. The data looks similar to my blog post, but is filled with other code and doesn't make much sense.

Here is a lean version of my list:

    myApp.views.PostListView = Ext.extend(Ext.Panel, {

    postStore: Ext.emptyFn,
    postList: Ext.emptyFn,
    id:'postlistview',
    layout: 'card',

    initComponent: function () {

       /* this.newButton = new Ext.Button({
            text: 'New',
            ui: 'action',
            handler: this.onNewNote,
            scope: this
        });*/

        this.topToolbar = new Ext.Toolbar({
            title: 'All Posts',
           /* items: [
                { xtype: 'spacer' },
                this.newButton
            ],*/
        });


        this.dockedItems = [ this.topToolbar ];

        this.postList = new Ext.List({
            store: myApp.stores.postStore,
            grouped: true,
            emptyText: '<div style="margin:5px;">No notes cached.</div>',
            onItemDisclosure: true,
            itemTpl: '<div class="list-item-title">{title}</div>' +
                            '<div class="list-item-narrative"><small>{body}</small></div>',

        });

        this.postList.on('disclose', function (record) {
            this.onViewPost(record);
        }, this),

        this.items = [this.postList];

        myApp.views.PostListView.superclass.initComponent.call(this);
    },
    onViewPost: function (record) {
        Ext.dispatch({
            controller: myApp.controllers.masterController,
            action: 'viewpost',
            post: record
        });
    },
});

And here is the "detail" view that is called on disclosure:

myApp.views.PostSingleView = Ext.extend(Ext.Panel, { 

    title:'Single Post',
    id:'postsingleview',
    layout:'card',
    style:'background:grey;',

    initComponent: function () {

        this.new1Button = new Ext.Button({
            text: 'Back',
            ui: 'back',
            handler: this.onViewList,
            scope: this,
            dock:"left"
        });

        this.top1Toolbar = new Ext.Toolbar({
            items: [
                this.new1Button
            ],

            title: 'Single Posts',
        });

        this.postSinglePanel = new Ext.Panel({
            layout:'fit',
            flex:1,
            scroll: 'vertical',
            style:'padding:10px;background:yellow;',
            itemTpl: '<tpl for=".">' +
                        '<div class="list-item-narrative">{body}</div>' +
                     '</tpl>',
        });

        this.dockedItems = [ this.top1Toolbar, this.postSinglePanel ];

        myApp.views.PostSingleView.superclass.initComponent.call(this);
    },

    onViewList: function () {
        Ext.dispatch({
            controller: myApp.controllers.masterController,
            action: 'viewlist',

        });
    },
});

And here is the controller that its talking to:

    Ext.regController('masterController', {


    'index': function (options) {

        if (!myApp.views.mainView) {
            myApp.views.mainView = new myApp.views.MainView();
        }

        myApp.views.mainView.setActiveItem(
            myApp.views.postView
        );
    },

    'viewpost': function (options) {

        myApp.views.postSingleView.postSinglePanel.update(options.post);
        myApp.views.postView.setActiveItem(
            myApp.views.postSingleView,
            { type: 'slide', direction: 'left' }
        );
    },

});

myApp.controllers.masterController = Ext.ControllerManager.get('masterController');

When the data comes out, it looks similar to this:

(the black boxes are "redacted" content, no error code there).

In closing, I believe that the controller is "dumping" the data into "MyApp.views.PostSingleView" rather than formatting it as I request in the TPL, though I'm not sure how to fix it. Any and all help MUCH appreciated!

UPDATE: As requested, here is the RegModel:

    Ext.regModel("CategoryModel", {
    fields: [
        {name: "id", type: "int"},
        {name: "title", type: "string"},
        {name: "body", type: "string"},
    ],
    hasMany: {
        model: 'Post',
        name: 'posts'
    }
});

And here is a sample of the json:

{
   "status":"ok",
   "post":{
      "id":1037,
      "type":"post",
      "slug":"post-title",

      "status":"publish",

Use the tpl config option of the Ext.Panel not the itemTpl which doesn't exist.

As someone has mentioned before, be careful when using a Model instance and the update method, you will need to use the model's data property.

Try using this:

myApp.views.postSingleView.postSinglePanel.update(options.post.data);

the reason is that post does not actually expose the underlying data directly, you need to use the property data for that.

Also any particular reason why you are docking the postSinglePanel? I would be very careful using too many docked items as they are a known source of bugs and layout issues.

A simple way is to write your own method to update child panels (you can also see to override the default update method)

myApp.views.PostSingleView = Ext.extend(Ext.Panel, { 
   initComponent: function () {
      // [...]
   },

   // [...]

   myUpdate: function(data) {
      this.postSinglePanel.update(data);
      this.doComponentLayout(); // not sure if necessary...
   }
});

and from your controller:

Ext.regController('masterController', {
    // [...]
    'viewpost': function (options) {

        myApp.views.postSingleView.myUpdate(options.post.data); // note the .data
        // [...]
    },

});
