Upgrade Notes

• The map component (RC1) is renamed to imagemap.
• Configurations that were specified in init-param of /WEB-INF/web.xmlmust be moved to /WEB-INF/zk.xml
• Listbox.clear() is removed. Use Listbox.getItems().clear() instead.
• Tree.clear() is removed. Use Tree.getTreechildren().clear() instead.
• Combobox.clear() is removed. Use Combobox.getItems().clear() instead.
• Radiogroup.clear() is removed. Use Radiogroup.getChilren().clear() instead.
• The close button of a window, enabled by use closable=true, sends the onClose event instead of the onShow event. By default, it detaches itself instead of hiding! Developers could override this behavior by overriding the onClose method.
• Initiator is moved from the com.potix.zk.ui.extpackage to the com.potix.zk.ui.util package. And, the signature of the doInit method becomes
  public void doInit(Page page, Object[] args);
• When Initiator.doInit() is called, page is not attached to a desktop yet. Developers have to access Executions.getCurrent().getDesktop()instead.
• IdSpace is moved from the com.potix.zk.ui.ext package to the com.potix.zk.uipackage.
• Textbox.getText() becomes protected. Use Textbox.getValue() instead.
• Inputable, Moveable, Openable,... are moved from the com.potix.zk.ui.event package to the com.potix.zk.ui.ext package.
• Use zk-FCKeditor-2.2-2006-03-31.zip or later.
• Use Session.getNativeSession() to retrieve HttpSession instead of Session.getAttribute("javax.servlet.http.HttpSession").
• The sytle-class element of lang-addon.xml is no longer supported. Use the propety element instead.
• LabellocatorHook is no longer required to declare in web.xml, because DHtmlLayoutServlet always loads WEB-INF/i3-label*.properties
• The signatures of Component.setVariable and getVariable are changed. An extra argument called local is added. To port your old codes, specify true to it.
• The event invocation sequence is changed a bit: event listeners are invoked before component's onXxx method.
• EventThreadInit.prepare() is added so you have to implement it.
• Language addons shall use extend instead of override.
• Image's alt property is removed. Use tooltiptext instead.
• DynamicAttributes are renamed to DynamicPropertied such that it is less confused with custom attributes.
• When ListitemRenderer.render() is called, the listitem being rendered has no child at all.
• Use instead of .
• The getPopup, isAutoCheck, setAutoCheck, isAutoPopup, and setAutoPopup methods of Menu are renamed to getMenupopup, isAutocheck, setAutocheck, isAutodrop and setAutodrop.
• The getPopup and closePopup method of Bandbox are renamed to getDropdown and closeDropdown.
• Executions.notify(Page,Object) is changed to Executions.notify(Desktop,Object)
• The isPopup, isOverlapped, isEmbedded and isModal methods of Window are renamed to inPopup, inOverlapped, inEmbedded and inModal.
