OpenCheatSheetHandler [message #532073]

Hi,

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

<extension
         point="org.eclipse.ui.menus">
      <menuContribution
            locationURI="menu:org.eclipse.ui.main.menu?after=additions">
         <menu
               id="mymenu.help"
               label="%Menu.Help">
            <menu
                  label="%Menu.Help.CheatSheet">
               <command
                     commandId="org.eclipse.ui.cheatsheets.openCheatSheet"
                     label="%cheatsheet.firststeps">
                  <parameter
                        name="cheatSheetId"
                        value="cheatsheet.firststeps">
                  </parameter>
               </command>
            </menu>
         </menu>
      </menuContribution>
   </extension>

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(OpenCheatSheetHandler.java:37)

BTW I've included org.eclipse.help, org.eclipse.help.base, org.eclipse.help.ui for that in my feature.

Any ideas what the problem could be?

Thanks, Luigi

Bonjour,
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...
Merci

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