I've tried to add a cheatsheet into my application. This cheatsheet is been referenced directly by the help menu.

But when I click on this menu-item in the application I got a NoClassDefFoundError.
java.lang.NoClassDefFoundError: org/eclipse/help/ui/internal/views/HelpTray
	at org.eclipse.ui.internal.cheatsheets.handlers.OpenCheatSheetHandler.execute(

BTW I've included,, for that in my feature.

Any ideas what the problem could be?

Thanks, Luigi

je me retrouve aujourd'hui avec exactement la même erreur, dans le même contexte de création de cheatsheets...
aurais-tu finalement trouvé une solution? Je ne trouve pas grand chose ailleurs...

You need to check the error log of your app. HelpTray is in but that bundle might not have started correctly.
