Eclipse Outline View is empty

Question

A simple one today. My Outline view in eclipse does not show me any methods or fields anymore. I have selected the few options that are available in the outline vie

Answer 1

Apparently the reason for this problem is that the DLTK (Dynamic Languages ToolKit) index is borken.

Following Five tips for speeding up Eclipse PDT and nWire, I have closed Eclipse, and only deleted the h2 database (*.db) files in /.metadata/.plugins/org.eclipse.dltk.core.index.sql.h2/.

When restarting Eclipse, the databases files are created again, and after that the Outline View is working again. IIRC, this is the second time that I had this problem (first with Eclipse 3.7.x and now 4.2) and that this solution worked for me.
