Class SelectedItemConverter

java.lang.Object

org.zkoss.zkplus.databind.SelectedItemConverter

All Implemented Interfaces:

Serializable, TypeConverter

Deprecated.

As of release 7.0.0, replace with new ZK binding.

public class SelectedItemConverter
extends Object
implements TypeConverter, Serializable

Convert selected item to bean and vice versa.

Before ZK version 3.6.2(included), when use data binding with selectedItem attribute of Listbox and/or Combobox, data binder will fire "onSelect" event automatically when the page is first loaded or model is changed. This is not consistent with ZK specification: only user action shall trigger component event. So since version 3.6.3, no longer the "onSelect" event will be fired(refer to Bug 2728704). However, some already implemented application might count on such "side effects". User can specify in application's WEB-INF/zk.xml following library-property to true to make it backward compatible (i.e. still fire the "onSelect" event when page is first loaded or model is changed)

    
        
                org.zkoss.zkplus.databind.onSelectWhenLoad
                true
