It's contributed by my plugin.

I've edited plugin.xml via the PDE interface. Here is something of what 
I have got:
-----------------
   <extension
         point="org.eclipse.ui.actionSets">
      <actionSet
            label="Gruppo di azioni"
            description="Menu delle funzionalità di &quot;Lexlooter&quot;"
            visible="false"
            id="it.unifi.ing.lexlooter.actionSet">
         <menu
               label="&amp;Lexlooter"
               id="LexlooterMenu">
            <separator name="saveGroup"/>
            <separator
                  name="openGroup">
            </separator>
            <separator name="toolGroup"/>
            <separator name="configGroup"/>
         </menu>
         <action
               label="&amp;Salva..."
               icon="icons/etool16/save.gif"
               class="it.unifi.ing.lexlooter.actions.SaveResult"
               tooltip="Salva tutti i modelli e i testi consolidati in 
un unico archivio"
               style="push"
               state="true"
               menubarPath="LexlooterMenu/saveGroup"
               id="it.unifi.ing.lexlooter.actions.SaveResult"/>
....
-----------------

then I have a SaveResult.java file that begins with something like:

-----------------
package it.unifi.ing.lexlooter.actions;
public class SaveResult implements IWorkbenchWindowActionDelegate
....
-----------------

I know that the methods IWorkbenchWindowActionDelegate.run and 
.selectionChanged have an IAction reference passed to them, but I would 
like to access that IAction also from other methods.

Or have I to use another approach?

Thanks
