The Ext GWT framework offers some rather sophisticated support for drag and drop in GWT applications. However dealings with drag and drop in TreeGrids can be complicated at times, since only limited documentation apart from the examples in the showcase is provided. Here some information, how it can be controlled,

If there are multiple dependent projects in an eclipse workspace, it can be tedious to run the unit test of all these projects manually. Often, a failed unit test caused by a change in a different project than where the unit test is located is only discovered with a significant
The question of the right programming language is one that has always spurned much controversy. Likewise, the idea that one day we could develop software by simply 'drawing' expressive models has as many advocators as opponents. The idea of domain specific languages could be one which helps us
Ubiquitous devices of all sizes have radically changed our reading experiences in the last couple of years. I have no problem in reading entire books using iBooks on the iPhone. Reading on the iPad has often been criticized for the potential strenuous effects of screen brightness. However, I most struggle
There are a number of plugins for eclipse, Maven and/or subversion, which allow the convenient and automatic determination of important project statistics such as the total lines of code in a project or the number of Java classes. However, sometimes one just needs these statistics quick and dirty and
Problem Java lists manage inserted objects based on their equality (see List JavaDoc). In some instances, it can be confusing that this equality has a different meaning than an equal identity of objects based on their reference. This becomes quite apparent in the following example: final List<String>
I made the very troublesome discovery that different rules apply for Gwt to convert Java objects to JavaScript objects and using Java objects as parameters in Gwt's remote procedure calls (RPC). Following a list of issues arising when using Gwt RPC (but not in Java->JavaScript conversion)
The Maven Gwt Plugin is a powerful tool in developing Gwt applications using Maven Build Management. I have set up my development environment to code and run JUnit test in eclipse IDE (without using eclipse IAM etc but the Maven Eclipse Plugin instead), and I test gwt code using the
We have presented a paper at the 44th Hawaiian International Conference on System Sciences (HICSS) 2011. Below the links for the paper as well as the slides presented: Links Link to citation on citeulike Link to full text article on IEEE Xplore (requires subscription to the IEEE Xplore digital library)
I am working with the Maven Eclipse Plugin, the Maven Bundle Plugin and the eclipse PDE. A common activity in this setup is to refresh projects in the workspace, since the Maven bundle plugin generates new MANIFEST.MF files (which I copy via Maven Ant Task), which become "out
Direct evaluate Remote Procedure Calls (deRPCs) in GWT seem to be promising approach to transfer objects from server to browser. Rather than encoding objects into a stream of text in a legacy format, deRPC sends objects as JavaScript statements from server to client. However, after some time of working with
One of the strengths of GWT, from my point of view, is that large portions of the code (eg business logic) can be tested with plain old JUnit tests, without the slightest interference from servers, web browsers and other constraints. However, certain parts of the code must be tested in
