ABAP Trapdoors: Type Lock-In

This is a repost of an article published on the SAP Community Network.

In the past ABAP Trapdoor blogs, I've written about various problems that can occur when actually writing code in ABAP. Today's issue is more about a structural or design problem. For this example, we'll use the following class hierarchy:


ABAP Trapdoors: LOOP Dizziness

This is a repost of an article published on the SAP Community Network.

First off, I'd like to apologize for the delay since my last ABAP trapdoor article. I'm really grateful for all of the kind responses I'm getting for these articles. However, having a 14-months-old toddler around invariably implies having all kind of germs around, and some of them apparently teamed up to knock me out for some time...

Eclipse PDE Headless Build: Beware of OpenJDK / Debian

If you're setting up a linux box to run an Eclipse PDE headless build and by choice or accident end up using a Debian system and again by choice or accident installed the OpenJDK, you'll probably see the following p2 director error message after enabling the p2 integration:

One or more certificates rejected. Cannot proceed with installation.

Eclipse PDE Headless Build: To Order!

If your product-based Eclipse PDE Headless Build seems to work just fine and creates some archives with files and executables inside, you might still experience one ugly problem:

Unable to acquire application service. Ensure that the org.eclipse.core.runtime bundle is resolved and started (see config.ini)

Test, one two

Someone probably should have double-checked this...


ABAP Trapdoors: The Myth of the Instance Constructor

This is a repost of an article published on the SAP Community Network.

Arguably one of the most misleading field values in the entire ABAP Workbench is this one:


ALV Grid Function Code Reference

Once again, I had to deal with the ALV Grid and its default toolbar. Since I'm notoriously bad when it comes to remembering the function code constants that are used to disable the toolbar buttons, I've thrown together a small reference card. Perhaps someone else might be interested in this too...

Xtext-Artikel veröffentlicht

The Linux-Magazin 02/2011 - that is available as of today - contains an article in which I describe how to use Xtext and the ex-oAW technologies Xtend, Xpand and Check to create a custom configuration DSL and a configuration file generator.

Addendum: In the meantime, the article has been made publicly available.

Graphiti Talk Slides

Attached to this article you will find the slides of my talk project.replaceAll("GMF", "Graphiti");. At the Eclipse Demo Camp I described my experiences during the replacement of the Graphical Modeling Framework with the relatively recent framework Graphiti.
