• Added methods
  • ItsNatDocument.isCreatedByStatelessEvent()
  • ItsNatEvent.getExtraParamMultiple(String)

Version 1.2

• CHANGED LICENSE TO BUSINESS FRIENDLY LGPL v3 !!
• Added methods:
  • ItsNatServletConfig.isUseSyncXHROnUnloadEvent()
  • ItsNatServletConfig.setUseSyncXHROnUnloadEvent(boolean)
  • ItsNatDocumentTemplate.isUseSyncXHROnUnloadEvent()
  • ItsNatDocumentTemplate.setUseSyncXHROnUnloadEvent(boolean)
• Added to Reference Manual: "5.1.2.23 Communication mode of internal unload event"

Version 1.1.2

• Fixed an important bug on JavaScript generation (usually MSIE v6-8 is affected), UPGRADE RECOMMENDED.
• Interface ItsNatHTMLDocFragmentTemplate moved to org.itsnat.core.tmpl package.
• Session is discarded when something goes wrong on serialization (session replication enabled), this allows a new ItsNat session is created and you have some option to avoid the problem (for instance attached clients do not work fine when session replication is enabled in Google App Engine).
• Fixed bug: NumberFormat and DateFormat shared objects specified in ItsNatDocumentTemplate or ItsNatServletConfig are now cloned per ItsNatDocument because they are not thread safe and cannot be shared between documents.
• Added methods:
  • ItsNatDocFragmentTemplate.loadDocumentFragment(ItsNatDocument,ItsNatServletRequest,ItsNatServletResponse)
  • ItsNatHTMLDocFragmentTemplate.loadDocumentFragmentHead(ItsNatDocument,ItsNatServletRequest,ItsNatServletResponse)
  • ItsNatHTMLDocFragmentTemplate.loadDocumentFragmentBody(ItsNatDocument,ItsNatServletRequest,ItsNatServletResponse)

Version 1.1.1

• Very improved support of session replication (ItsNatServletContext.setSessionReplicationCapable(boolean) set to true), for instance in Google App Engine (GAE):
  • Memory leaks have been fixed because the cleaner thread (CleanerThread) of Batik cannot be launched in GAE. ItsNat NO LONGER needs this cleaner thread and is not launched anymore.
  • Data size on serialization has been heavily reduced in some cases (many partial page changes with attribute ids). Batik management of elements with ids has been fully changed avoiding unnecessary cached elements (serialized alongside the session).
  • New methods:
    • ItsNatServletContext.isSessionSerializeCompressed()
    • ItsNatServletContext.setSessionSerializeCompressed(boolean)
    • ItsNatServletContext.isSessionExplicitSerialize()
    • ItsNatServletContext.setSessionExplicitSerialize(boolean)
  • Workaround for a bug of javax.swing.text.AbstractDocument (this error is still present in Java 1.6), registered DocumentListener and UndoableEditListener listeners are not serialized. This class is used as default data model of text components.
  • Fixed: NameValue is not serializable.
  • Fixed problems in applications with two or more ItsNat based servlets.
  • Fixed other bugs.
  If you are using session replication, upgrading is strongly recommended.
• Added method: ItsNatInclude.includeFragment(String)
• Supported SVGWeb 2010-02-03 "Lurker Above" (previous versions deprecated).
• Fixed bug: XHTML namespace and another different namespace declared in HTML element causes reinsertion of this element.
• Fixed bug: SVGWeb does not work in attached clients in full remote control mode (SVGWeb recently changed to SVGLoad instead load event to notify when it is ready).
• Fixed regression introduced by version 1.1 in Pocket IE: fail accessing attributes and content of HEAD element.
• Reference Manual: "2.6.3 Session management" and "2.6.4 Google Application Engine support" have been rewritten because in spite of some limitations, session replication is now a first class citizen in ItsNat.
• Feature Showcase:
  • Fixed a bug launching servlets (both must define the same values in ItsNatServletContext
  • Improved scripts to upload the application to GAE

Version 1.1

• New feature "Disconnect Nodes from Client": this feature, complementary to node caching in templates to save server memory, allows removing nodes in server but not in client saving server memory, the client DOM subtree can be changed freely. Use this technique when you need to render in some way a DOM subtree (of course in server) and not going to be changed anymore. Disconnection is reversible (client is again in sync with server) calling ItsNatDocument.reconnectChildNodesToClient(Node) or adding a child node to the node which content was disconnected.
  
  New Methods:
  • ItsNatDocument.disconnectChildNodesFromClient(Node)
  • ItsNatDocument.reconnectChildNodesToClient(Node)
  • ItsNatDocument.isDisconnectedChildNodesFromClient(Node)
  
  Feature Showcase: Added "Core/Extreme Mashups/Disconnect Nodes from Client" example.
• Added tolerance to intrusive nodes inserted alongside HEAD and BODY elements by non-ItsNat JS libraries (usually browser extensions). In previous version of ItsNat, extraneous elements were automatically removed.
• Added tolerance to intrusive nodes inserted in the end of HEAD and BODY elements by non-ItsNat JS libraries (usually browser extensions and other JS libraries). In previous version of ItsNat, only one element introduced by FireBug was ignored.
• Improved speed in server when detecting whether innerHTML can be used generating JavaScript code (notably when inserting big subtrees).
• BlackBerry Browser of JDE 6.0 (Torch 9800) is officially supported in spite of it worked on v1.0. This new browser is now WebKit based very different to previous versions.
• Supported SVGWeb 2010-08-10 (Owlephant), previous version deprecated. ItsNat also adds a workaround for a SVGWeb bug (event listeners are not correctly removed in removeEventListener).
• Fixed bug (regression): events in Batik applet are not working.
• Workaround for a Chrome bug: Event.timeStamp is not an integer in Chrome.
• Reference Manual:
  • Added "6.23 SAVING SERVER MEMORY: DISCONNECTED NODES".
  • Because of improved tolerance to DOM modifications in client by non-ItsNat JavaScript code, the chapter "6.42 EXTERNAL JAVASCRIPT LIBRARIES AND BROWSER EXTENSIONS" has been rewritten.
