Google Web Toolkit 1.1.0 Release Notes

New Features

• FileUpload widget
  The much-requested file upload widget
• FormPanel widget
  Easily submit traditional HTML forms from GWT apps
• RPC optimizations
  Client and server performance improvements and a more compact wire format
• Automatic Resource Injection
  Modules can contain references to external JavaScript and CSS files, causing them to be automatically loaded when the module itself is loaded
• Internationalization
  Easily localize strings and formatted messages
• XML classes
  An XML library based on the W3C DOM
• JSON classes
  JSON has moved into gwt-user.jar, and it's much faster than the sample that shipped with 1.0.21
• JUnit enhancements
  Unit tests are much, much faster than in 1.0.21, easier to configure, and you can now test asynchronous things like RPCs and timers
• Javadoc
  Now included for your convenience, with sample code fragments
• gwt-servlet.jar
  Although you should continue to build against gwt-user.jar as always, you only need to deploy gwt-servlet.jar with your webapps; it contains the subset of gwt-user.jar you'll need to support RPC

Fixed Issues

• Issue #4794724 - Servlet container problems due to gwt-user.jar including javax.servlet classes

• Issue #6606675 - ListBox and Image widgets are missing CSS style names
• Issue #5922226 - Casts from interface types to concrete class types can fail
• Issue #4137736 - Referencing an outer local from a field initializer causes NullPointerException
• Issue #2518888 - Problem with "return" statements in constructors
• Issue #9984353 - Hosted Mode server throws IllegalArgumentException when system is set to non-english locale
• Issue #3733199 - Shrinking Grid via resizeRows() leads to inconsistent state
• Issue #7659250 - Hosted mode on default Fedora Core 5 complains of missing libstdc++.so.5
• Issue #6531240 - Empty if, while, do, and for statements cause Compiler Error
• Issue #4927592 - Multiple initializations in for loop initializer causes internal compiler error.

See the appendix of fixed issues for the nitty-gritty list of things that we have fixed in this release, including smaller issues.

Behavioral Changes

Important changes in the behavior of existing GWT features.

Module Source and Public Paths

• In previous versions of GWT, source and public path inclusions were based on physical directory structure; only files physically located with the module would be included. Going forward, source and public path inclusions are based on logical package structure. Once a package has been included, any files in that package become visible no matter where they are physically located.

JUnit Modules

• GWT test modules (that is, modules intended to run GWTTestCase-derived JUnit test cases) no longer need to inherit the com.google.gwt.junit.JUnit module. Additionally, it is no longer an error to declare entry points within a test module (they will be ignored when running under JUnit). Most test cases can now simply use the existing application module, which should simplify test case configuration.

Breaking API Changes

com.google.gwt.user.client.ui.HasWidgets

• We've moved add(), remove(), and clear() into this interface, so that any widget that can contain other widgets will be bound to this contract.
• The add() method no longer returns a boolean. If a panel either cannot add a child widget without extra arguments, or cannot accept further widgets, it will throw an exception. This is in keeping with the fact that this is usually the result of an error in the code.
• Its iterator is now required to support the remove() method.

com.google.gwt.user.client.ui.Composite

• Composites must now call initWidget() in their constructors, rather than setWidget(). This is more indicative of its actual purpose, and also serves to clear up any confusion with SimplePanel's setWidget() method. Composite.setWidget() is now deprecated, and will be removed at the end of beta.

com.google.gwt.user.client.ui.SimplePanel and subclasses

• We have added setWidget() to SimplePanel, which has more appropriate semantics for a panel that can contain only one child. The add() method is still present through the HasWidgets interface, but will fail if a widget is already present. This change is most likely to affect you if you use DialogBox or PopupPanel. To fix it, simply change your call to add() to setWidget() instead.

com.google.gwt.user.client.Cookies

• Cookies.getCookie() is now static, as it should have been from the beginning. There is no need to instantiate this class now.
• You can now set cookies as well!
