Dot notation with Ext.form fields' name config option

[ilker]

Hi, everyone...i want to use dot notation with values of name config options of form components because of struts BeanUtils.populate method...When the form is submitted it populates my actionform...

i have used this notation at pure html:

.......
<input type='hidden' name='employeeType.id' value="1"/>
.......

however when i use the same notation with ext.form's fields , the form submission fails due to null value...
(A piece from my sample code):

this.add({ 
            xtype:'combo',
            name : 'employeeType.id',
            id : 'employeeType.id',
             fieldLabel : 'Employee Type',
            valueField:'id',
            displayField : 'type',
            mode : 'local',
            store: new Ext.data.Store({ 
                proxy : new Ext.data.HttpProxy({ 
                        url : 'GetEmployeeTypesAction.do'
                        }),
                baseParams: { 
                         respObjName: 'empType',
                         javaFields: new Array(('id'),('type')),
                         extFields:     new Array(('id'),('type'))
                        },
                reader: new Ext.data.JsonReader({ 
                        root: 'empType'
                        }, Ext.data.Record.create([{name: 'id'},{name: 'type'}])),
                autoLoad : true
            })
        });

what do i have to do? or what am i doing wrong?
Thx for your replies in advance

I assume you want 'hiddenName' instead of 'name'?

Thx for your excellent reply Condor...Besides causing submission failure for combo component, it fails form-submission for other components... for instance, take 'hidden' component:

this.add({ 
                xtype : 'hidden',
                name : 'mails[0].eMail',
                value : mailsStore.getAt(i).get('email')
            });

Thx for your replies in advance...
P.S. dot-notation works perfect with poor HTML DOM Elements, likewise Array-Notation does...
