Page 188 — The third step says to use the filter box to find the Help feature. Due to a bug in the way PDE works, doing this can sometimes cause other, previously selected features to be unselected. We suggest that you simply turn off categorization and scroll to “Eclipse Help System” and select that feature.
Note — The Help UI requires the UI forms bundle (org.eclipse.ui.forms). This is not part of the standard RCP feature and so typically would not be part of your target platform. We have added it manually in the provided target definition in the misc folder as a convenience. As an alternative, you could add the Eclipse Platform SDK feature from the Galileo repository to your target. This includes UI forms, in addition to many other things, some of which you may find useful.
