After upgrading to 0.5.1 I followed the migration guides, but I am stumped by the change to the AbstractSaveableTreeView. Here is how I used it before to add actions to the the view menu:

class MasterTreeView extends AbstractSaveaclass MasterTreeView extends AbstractSaveableTreeView {
	protected List<Action> actions = new Arclass MasterTreeView extends AbstractSaveableTreeView {
	protected List<Action> actions = new Arclass MasterTreeView extends AbstractSaveableTreeView {
	protected List<Action> actions = new ArrayList<Action>();
	private RemoveAllViewSelectorsAction removeAllViewerSelectors;
	private OCLFilterSelectionAction oclFilterSelectionAction;

	@Override
	public void menuAboutToShow(IMenuManager manager) {
		super.menuAboutToShow(manager);
		manager.add(removeAllViewerSelectors);

	}rayList<Action>();
	private RemoveAllViewSelectorsAction removeAllViewerSelectors;
	private OCLFilterSelectionAction oclFilterSelectionAction;

	@Override
	public void menuAboutToShow(IMenuManager manager) {
		super.menuAboutToShow(manager);
		manager.add(removeAllViewerSelectors);

	}rayList<Action>();
	private RemoveAllViewSelectorsAction removeAllViewerSelectors;
	private OCLFilterSelectionAction oclFilterSelectionAction;

	@Override
	public void menuAboutToShow(IMenuManager manager) {
		super.menuAboutToShow(manager);
		manager.add(removeAllViewerSelectors);

	}bleTreeView {
	protected List<Action> actions = new ArrayList<Action>();
	private RemoveAllViewSelectorsAction removeAllViewerSelectors;
	private OCLFilterSelectionAction oclFilterSelectionAction;

	@Override
	public void menuAboutToShow(IMenuManager manager) {
		super.menuAboutToShow(manager);
		manager.add(removeAllViewerSelectors);

	}

I see that there now there is no longer a menuAboutToShow method. How with 5.1 can I add actions to the View menu?

thanks
John

Sorry for the format problems code snippet should be:

class MasterTreeView extends AbstractSaveableTreeView {
	protected List<Action> actions = new ArrayList<Action>();
	private RemoveAllViewSelectorsAction removeAllViewerSelectors;
	private OCLFilterSelectionAction oclFilterSelectionAction;

	@Override
	public void menuAboutToShow(IMenuManager manager) {
		super.menuAboutToShow(manager);
		manager.add(removeAllViewerSelectors);

	}

Hi John,
since 0.5.0 version you can do all by DSL, see the following part of documentation:
https://www.eclipse.org/emf-parsley/documentation.html#par12

Let me know if you have problem
Best regards
Vincenzo Caselli

Hi John

as described in the migration guide, we changed the context menu
handling to make it easier; in particular, it should be easier to
customize the context menu in the DSL.

Can you implement the actions with the DSL section?

If you can't, and you really want to manage the menu yourself, I think
you can still retrieve the Menu of the underlying viewer:

viewer.getControl().getMenu()

and then create a new menu menager on top of that. (You can get
inspiration from ViewerContextMenuHelper).

It might also be worthwhile to reintroduce some API in our views to get
access to the menu manager... in that case, please file a bug.

cheers
Lorenzo
