GWT 1.4 thoughts

I’ve been working with GWT 1.4 RC1 for the past few months. I’ve really enjoyed a number of things about this release, including some of the new widgets (the auto suggest box is pretty cool), and the size decrease (we saw size decreases of 20% without changing a bit of code). More on the release in the release announcement.

However, the number one reason you should upgrade to 1.4 is that it allows you to share value objects between the GWT view throughout the entire Java stack, all the way down to Hibernate (or whatever other data access layer you use). The reason is that is now a synonym for IsSerializable, the marker interface for Java objects that can be sent to the client. Obviously, if you are not using the RPC mechanism, this is much less important.

There is still some doubt about the GWT 1.4 release date, but you can check out the auto suggest box in action at Colorado HomeFinder (the browse homes link in the nav bar). I think this will be a killer release when it finally happens.
