[kkbear]

HI all~sorry for my english

new Ext.form.ComboBox( {
    fieldLabel : 'BookStatus',
    name : 'model.bookCategoryID',
    store : new Ext.data.Store( {
        proxy : new Ext.data.HttpProxy( {
            url : './bookManagement/listAllStatusType.action'
        }),
        reader : new Ext.data.JsonReader( {}, [ {
            name : 'id',
            mapping : 'id',
            type : 'int'
        }, {
            name : 'typeName',
            mapping : 'typeName'
        }])
    }),
    displayField : 'typeName',
    valueField : 'id',
    hiddenName : 'bookStatusQueryConditionDTO.statusId',
    typeAhead : true,
    mode : 'remote',
    triggerAction : 'all',
    emptyText : 'Please select...',
    selectOnFocus : true,
    readOnly : true
})

Here,I have two problem:
1:when I select a value, I can not make it return to empty status (Please select...);
2:the displayField is a i18n resource,how to change the typeName just like renderer method of ColumnModel.

I can help on the first point, but not the second.

To get the value back to nothing in a combo, you need to either call the reset () function for the combo, or you need to have a record in your data store with a blank value that can be chosen by the user.
