Actions in NetBeans module - context menu, main menu

I am developing NetBeans module and I have declared an action (using annotations, they are translated to layer.xml record) which works with my custom开发者_StackOverflow社区 project type (EsperProject class):

@ActionID(category = "Run", id = "my.package.RunEsperAction")
@ActionRegistration(displayName = "My Action", asynchronous=true)
@ActionReferences({
    @ActionReference(path = "Menu/BuildProject", position = 0)
})
public final class RunEsperAction implements ActionListener {

    private final EsperProject project;

    public RunEsperAction(EsperProject project) {
        this.project = project;
    }

    @Override
    public void actionPerformed(ActionEvent ev) {
       // do sth with project
    }
}

I can run the action from the BuildProject Menu (which is actualy Run menu), but i CANNOT make it work in two cases I need (both called asynchronously as declared in the annotation):

1. I'd like to run the action from the project context menu.

2. I need to have the action triggered when my EsperProject is run from the main menu item "Run Main Project".

Thanks for any suggestions.

1.I'd like to run the action from the project context menu.

It will be possible just by adding @ActionReference(path = "Project/Actions", position = 0) to @ActionReferences

I have figured out the first point: To run the action from the context menu, we must add it to the getActions() method of the project root node, something like this:

class RootNode extends FilterNode {
    @Override
    public Action[] getActions(boolean arg0) {
        List<Action> nodeActions = new ArrayList<Action>();
        nodeActions.addAll(Utilities.actionsForPath("Actions/MyCategoryInLayer"));
        return nodeActions.toArray(new Action[nodeActions.size()]);
    }
}

The action appears in the context menu of the project and is run asynchronously. However, overriding "Run main project" is still imposible for me. I try the simmilar aproach but this fails:

@Override
public void invokeAction(String actionName, Lookup lookup) throws IllegalArgumentException {

if (actionName.equalsIgnoreCase(ActionProvider.COMMAND_RUN)) {
    List<? extends Action> runActions = Utilities.actionsForPath("Actions/Run");
        for (Action action : runActions) {
            action.actionPerformed(null);
        }
}
