Looking back on another eventful year for the RAP project, today we're proud to publish the results in a new release, RAP 2.2. Let's have a look at the highlights: Client-side Scripting We started off the work on RAP 2.2 with integrating the ClientScripting from the Incubator project into RWT. With this new feature, you can now attach scripted listeners to a widget. Those listeners are directly...

It is always great to see the adoption of your open source project at large enterprises. It is even better when you receive positive feedback from those organizations. Without a doubt, it is best when those enterprises talk publicly about their positive experience. EclipseCon Europe 2013 was the venue where Stefan Milchram of AMOS (Allianz Managed Operations and Services) reported about their use of single sourcing...

The ability to upload files is key functionality for every Web application and, naturally RAP can upload files too. In the beginning ( RAP 1.2 ), this functionality was provided by a custom widget called Upload. This widget was based on an early version of the Qooxdoo UploadWidget contribution project. In RAP 1.4 the old Upload widget was deprecated and replaced by a new FileUpload RWT...

One strength of Eclipse is the possibility to use the same code on desktop clients as well as in web clients. The same application can run as an installed desktop application and in the web browser, with only few adjustments for both platforms. In our experience, about 80% to 90% of the code can run in both environments, if some guidelines are followed (i.e. no...

A while ago we started a new RAP Incubator project, the DropDown widget. This is basically a List widget that can be attached to a text field, like the pop-up of a combo box. In itself this widget isn't terribly useful, but it provided the basis for the new AutoSuggest component, which is currently part of the same incubator project. You may also know these kind...

The first milestone of RAP 2.2 has been published last Friday. It's main attraction is the RWT Scripting feature which was formerly known as the incubator "ClientScripting" project. If you are currently using ClientScripting and wish to upgrade to RAP 2.2 (which will be released in December 2013), you should be aware of some breaking changes*: Namespace: The ClientListener has been...

RAP 2.0 introduced the JavaScriptLoader service to allow custom widgets to load their scripts dynamically. However, because this is based on an "eval"-like JavaScript feature, the scripts did not appear like all other in the browser developer tools, and setting break points was not possible. The same exact same issue always existed for ClientListener. For the JavaScriptLoader this will be fixed in RAP 2.2M1, but...
