ABAP Trapdoors: LOOP Dizziness

published by Volker Wegert on 28. April 2011 - 0:00

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: 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)

ALV Grid Function Code Reference

published by Volker Wegert on 20. February 2011 - 0:00

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

published by Volker Wegert on 5. January 2011 - 0:00

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.
