Hello,

I'm have combo box like this:
Code:
var groupLab = new Ext.form.ComboBox({
    id: 'groupLab',
    name: 'groupLab',
    fieldLabel: 'Kelompok',
    emptyText: '',
    valueField:'id',
    displayField:'val', 
    selectOnFocus:true,
    forceSelection: true,
    typeAhead: true,
    triggerAction: 'all',
    listWidth: 150,
    mode: 'local',
    store: groupLabStore,
    anchor:'95%',
    listClass: 'x-combo-list-small',
    listeners:{
        select:{
            fn:function() {
                Ext.getCmp('saveGr').focus('', 10);
            }
        }
    }
})
on select event I want the focus change to a button. But, the focus did not change. But when i set the focus to textfield, the focus is change.
So can anyone can help me to fix this?
