Timeline canEditLane(false) not working

[edulid]

public void onModuleLoad() {

        VLayout vlayout = new VLayout();
        final Timeline calendar = new Timeline();
        calendar.setHeight(451);
        calendar.setStartDate(new Date(112, 5, 2));
        calendar.setEndDate(new Date(112, 5, 22));
        calendar.setCanEditLane(true);
        calendar.setShowEventDescriptions(false);

        HeaderLevel[] headerLevels = new HeaderLevel[] { new HeaderLevel(TimeUnit.WEEK),
                new HeaderLevel(TimeUnit.DAY) };
        calendar.setHeaderLevels(headerLevels);
        calendar.setLaneFields(new ListGridField[] { new ListGridField("title", "Developer", 120) });
        calendar.setLanes(TimelineLaneData.getRecords());
        calendar.setData(TimelineData.getRecords());
        calendar.setCanEditLane(false);

        vlayout.addMember(calendar);

        IButton removeBtn = new IButton("Remove first lane");

        removeBtn.addClickHandler(new ClickHandler() {

            @Override
            public void onClick(ClickEvent event) {
                calendar.removeLane(calendar.getLanes()[0]);
            }
        });
        vlayout.setWidth100();
        vlayout.setHeight100();
        vlayout.addMember(removeBtn);
        vlayout.draw();
    }

If I try to drag an event to another lane, it is not possible, which is correct.
But clicking on an event I see the lanes in a dropbox, and changing the lane there is possible.
However, on the docs I read:

Can events be moved between lanes? If so, the event can be dragged to a different lane and, when it's editor is shown, an additional drop-down widget is provided allowing the user to select a different lane.

Using smartgwt 6.0-p20160813 power

This is fixed for builds dated August 19 and later.
