[SOLVED] form load(), this.processResponse is not a function

[atze]

I have problem with form load() function. When I don't POST parameter and don't set @extdirect-len 3 when form is populate otherwise i get error.What is wrong?

js:

Ext.onReady(function(){

    Ext.app.EXTDIRECT_API.enableBuffer = 100;
    Ext.Direct.addProvider(Ext.app.EXTDIRECT_API);
    
    // provide feedback for any errors
    Ext.QuickTips.init();
    
    var basicInfo = new Ext.form.FormPanel({
    
        title: 'Basic Information',
        border: false,
        padding: 10,
        buttons: [{
            text: 'Submit',
            handler: function(){
                basicInfo.getForm().submit({
                    params: {
                        foo: 'bar',
                        uid: 34
                    }
                });
            }
        }],
        
        defaults: {
            anchor: '-20'
        },
        
        defaultType: 'textfield',
        items: [{
            fieldLabel: 'Name',
            name: 'name'
        }, {
            fieldLabel: 'Email',
            msgTarget: 'side',
            name: 'email'
        }, {
            fieldLabel: 'Company',
            name: 'company'
        }],
        
        api: {
            load: myDirect.direct.action_get
            //submit: myDirect.direct.action_update
        },
        paramOrder: ['item1', 'item2', 'id']
    
    });
    
    var accordion = new Ext.Panel({
        layout: 'accordion',
        layoutConfig: {
            autoWidth: false
        },
        renderTo: Ext.getBody(),
        title: 'My Profile',
        width: 300,
        height: 240,
        items: [basicInfo]
    });
    
    basicInfo.getForm().load({
        params: {
            id: 1,
            item1: 'item1',
            item2: 'item2'
        },
        //waitMsg: 'Load...',
        success: function(form, action){
            console.log("SUCCESS");
        },
        failure: function(form, action){
            console.log("FAILURE");
                        Ext.Msg.alert("Load failed", action.result.errorMessage);
        }
        
    });
    
}); 

response:

{"action":"direct","method":"action_get","type":"rpc","tid":2,"result":{"success":true,"data":{"foo":"aaa","name":"aaa aaa","company":"i1: item1, i2: item2, i3: 1","email":"aaa@aaa.aaa"}}} 

error:

var result = this.processResponse(response);

I have API param lenght as string, must by a integer:

Ext.app.EXTDIRECT_API = {"url":"http:\/\/localhost\/kohana\/pl\/extdirect\/router","type":"remoting","actions":{"direct":[{"name":"action_get","len":   "3"   }],"index":[],"news":[],"page":[],"signin":[],"signout":[]},"namespace":"myDirect" 

ok:

Ext.app.EXTDIRECT_API =  {"url":"http:\/\/localhost\/kohana\/pl\/extdirect\/router","type":"remoting","actions":{"direct":[{"name":"action_get","len":   3   }],"index":[],"news":[],"page":[],"signin":[],"signout":[]},"namespace":"myDirect"
