Opening WebDynpro Configurations in ADT

It seems ABAP WebDynpro gets retired sooner than this issue. A nice error message is welcoming You in ADT when opening WebDynpro configurations.

Browser not supported

Microsoft Internet Explorer 11 and other legacy browsers are no longer supported. For more information see note 1672817.

If you look at your eclipse configuration You’ll find that eclipse (so their plugins as well) should use the default system browser or the one you selected/added manually. However this setting is not really picked up.

To fix that issue, close eclipse and add a new line specifying edge as web browser into the eclipse.ini configuration file residing next to eclipse.exe.

The right place to add the magical line is below -vmargs

-vmargs
-Dorg.eclipse.swt.browser.DefaultType=edge

Start eclipse and try to launch a GUIBB config for example. Now it should work.

Note: some temporary side effects may occur. Please close all your tabs in eclipse. F2 object information might be strange looking. Just resize it and restart eclipse. That should fix it ;).
Using other than edge is not working/buggy.
