sencha touch search form - sencha-touch

Question

I really hope someone can help me, It seems like this should be obvious but sencha documentation isn't very easy to read and incomplete. I am trying to build a search form but it doesnt seem to take the store or the url and I can't figure out how to add parameters like page? Can anyone help? This code just produces Failed to load resource: null.
var searchField = new Ext.form.Search({
value:'Search',
url: 'someurl',
store: this.data_store,
cls:'searchfield',
listeners: {
focus: function(){ searchField.setValue(''); },
blur: function(){ if( searchField.getValue()=='' ){ searchField.setValue('Search'); } },
success: function(e){
console.log(e);
}
}
});
this.dockedItems = [ searchField ];

Ext.form.FormPanel doesn't take a Ext.data.Store or Ext.data.Model directly but does deal with Instances of Ext.data.Model. Lets say you have the following model:
Ext.regModel('MyForm', {
fields: [{name: 'id', type: 'int'},'name','description']
proxy: {
type: 'ajax',
url: 'url_to_load_and_save_form'
}
})
Now your form definition would look something like this:
Ext.form.MyForm = Ext.extend(Ext.form.FormPanel, {
record : null,
model: 'MyForm',
items: [{
xtype: 'hidden',
name: 'id'
},{
xtype: 'textfield',
name: 'name',
allowBlank: false
},{
xtype: 'textarea',
name: 'description'
}],
submit : function(){
var record = this.getRecord() || Ext.ModelMgr.create({}, this.model);
this.updateRecord(record , true);
record.save({
scope: this,
success : function(record, opts){
this.fireEvent('saved', record);
},
callback: function(){
this.setLoading(false);
}
});
}
});
Ext.reg('MyForm',Ext.form.MyForm);
Of course you should add in some validations and a button to actually call the Ext.form.MyForm.submit method.
