GWT ramblings of a Flex developer – localization / I18N

January 30, 2012

Hello again,

This time I want to talk about localization (a.k.a. i18n).

As Flex developers, as I assume you already know, all you have to do is create a *.properties file (say and in it define keys with localized values, like:


Then, in the main application mxml, you would define the resource bundles:


And basically you’re done. All you need to do to use it, is use the ResourceManager class to access the localized value of the key.

Simple stuff, right?

Not so with GWT…

GWT ramblings of a Flex developer – live search component

January 15, 2012

Recently, I had to create a custom component that does live filtering on data presented in a grid.

If you are reading this series, you probably know how this can be done in Flex. If you don’t, a quick google search will probably point you in the right direction. Enough to say that in envolves a custom component to get the search criteria and a filter function on the grid’s dataProvider ArrayCollection.

I was surprised this is relatively straight forward in GWT (using uiBinder and GXT 3.0)

Is Flex dead to be replaced by HTML5?

September 3, 2011

Over the past few months, I have heard that question many times.

Many think HTML5/JavaScript is going to replace it, and with Adobe releasing Edge it seemed to be a valid point.
Deepa Subramaniam, Senior PM for the Flex team, alleviates those concerns with her post (rather a post on the Flex team blog).

It is a must read.

Extending AIR for Android

August 2, 2011

Currently, Flex 4.5 / AIR 2.6 for Android provides a consistent platform for desktop and mobile apps. While consistency is very important there are times when developers need to extend beyond the common APIs.

This article, posted by James Ward on his blog, will walk you through how to integrate AIR for Android applications with other native APIs and functionality in the Android SDK. It covers three common use cases for native extensibility: System Notifications, Widgets, and Application Licensing.

This is a great post that alleviates my biggest concern regarding the usability of Flex as a development platform for mobile applications. I intend to use this information on Tikal‘s next FuseDay, in the session for developing a mobile application over Flex that needs some native APIs.
