Extjs 4, forms with checkboxes and loadRecord - forms

Question

In my Extjs4 application I have a grid and a form.
The user model:
Ext.define('TestApplication.model.User', {
extend: 'Ext.data.Model',
fields: [
{ name: 'id', type: 'int', useNull: true },
{ name: 'email', type: 'string'},
{ name: 'name', type: 'string'},
{ name: 'surname', type: 'string'}
],
hasMany: { model: 'Agency', name: 'agencies' },
});
And the Agency:
Ext.define('Magellano.model.Agency', {
extend: 'Ext.data.Model',
fields: [
{name: 'id', type: 'int', useNull: true},
{name: 'name', type: 'string'}
]
});
Then in my form I'm creating the checkboxes:
[...]
initComponent: function() {
var store = Ext.getStore('Agencies');
var checkbox_values = {xtype: 'checkboxfield', name: 'agencies[]'};
var checkboxes = []
store.each(function(record){
var checkbox = {xtype: 'checkboxfield', name: 'agency_ids',
boxLabel: record.get('name'), inputValue: record.get('id')};
checkbox.checked = true;
checkboxes.push(checkbox)
});
this.items = [{
title: 'User',
xtype: 'fieldset',
flex: 1,
margin: '0 5 0 0',
items: [{
{ xtype: 'textfield', name: 'email', fieldLabel: 'Email' },
{ xtype: 'textfield', name: 'name', fieldLabel: 'Nome' },
}, {
title: 'Agencies',
xtype: 'fieldset',
flex: 1,
items: checkboxes
}];
[...]
Everything works well for sending form I am receiving all the data and can save it into database.
When user clicks on the grid the record is loaded in the form with the standard:
form.loadRecord(record);
The problem is that the checkboxes are not checked. Are there any naming conventions for checkbox elements so Extjs can detect what to set? How can I setup the relations so the form will understand what to check? Or should I do everything by hand?

Answer 1

In your form, you can do something like this :
{
xtype: 'checkboxfield',
name: 'test',
boxLabel: 'Test',
inputValue: 'true',
uncheckedValue: 'false'
}

Answer 2

I believe you have to use someCheckbox.setValue(true) to check a checkbox dynamically, or to uncheck someCheckbox.setValue(false)
