load form data into fields in nested container

[bruijn88]

Hi all!

I'm having some troubles loading form data (populating fields) into fields which are located in a nested container in the form.

I went from this example (form 5).
Code is as follows:

MyForm = Ext.extend(Ext.form.FormPanel, {

    initComponent: function () {
        var config;

        config = {
            url: 'save.php',
            reader: new Ext.data.JsonReader({
                idProperty: 'id',
                fields: ['id', 'introduction', 'title', 'content']
            }),
            items: [{
                xtype: 'textarea',
                name: 'introduction'
            }, {
                xtype: 'tabpanel',
                plain: true,
                activeTab: 0,
                deferredRender: false,
                defaults: {layout: 'form'},
                items: [{
                    title: 'Foo',
                    items: [{
                        xtype: 'textfield',
                        name: 'title'
                    }, {
                        xtype: 'textarea',
                        name: 'content'
                    }]
                } /* more tabs */]
            }]
        };

        Ext.apply(this, Ext.apply(this.initialConfig, config));
        MyForm.superclass.initComponent.apply(this, arguments);

        this.load({
            url: 'data.php'
        });
    }

}); 

Example response:

{"id":1,"introduction":"Intro","title":"Foo","content":"Lipsum..."}

While i was digging i discovered that 'Ext.form.BasicForm.findField' only looks in it's own 'items' collection and doens't cascade/recurse into underlying containers. Therefore it only finds the 'introduction' field and populated that, but not the 'title' and 'content' fields.

Does anyone have an idea how to solve/work around this?

Thank in advance,
Zogs

I copied your code exactly (and added a line to create a new MyForm() and render it) and it works for me... I see all 3 fields populated.

[EDIT]
I tested with ext-3.3.1

johnathan,

thanks for your reply. In all honesty, i haven't tested the -exact- code i posted. It's a stripped version of what i'm really working with, but is essentially the same.
I'm surprised it works for you. Guess i need to run some more (isolated) tests..

What version of Ext are you using?

johnathan,

Found it! Typo in reader config (fields did not match response). ><
I'll be in a corner crying if anyone needs me..

Zogs.
