ContextMenu is invisible

[jouni]

I created a ContextMenu (vaadin-context-menu-0.7.4).

 ContextMenu contextMenu = new ContextMenu(this, false);
        contextMenu.setAsContextMenuOf(butTest);

        contextMenu.addContextMenuOpenListener(new ContextMenu.ContextMenuOpenListener() {
            public void onContextMenuOpen(ContextMenu.ContextMenuOpenListener.ContextMenuOpenEvent event) {
                Notification.show("Context menu on "
                        + event.getSourceComponent().getCaption());
            }
        });

        MenuItem basic = contextMenu.addItem("Basic Item", new ContextMenu.Command() {
            public void menuSelected(com.vaadin.addon.contextmenu.MenuItem selectedItem) {
                //main.addWindow(getAboutDialog());
                labAction.setValue("ContextMenu item 'Basic Item' selected " );
            }
        });

        MenuItem second = contextMenu.addItem("Second Item", new Menu.Command() {
            public void menuSelected(com.vaadin.addon.contextmenu.MenuItem menuItem) {
                labAction.setValue("ContextMenu item 'Second Item' selected " );
            }
        });

When I right mouse click on butTest I see a notification "Context menu on ..." only. But the Context menu is invisible.

What I missed?
Please help me to understand what need to do to show a context menu.

It happens exactly to me. Just after use 'fetch' option in <vaadin.widgetset.mode> (yesterday all was working). No matter if right now I recompile widget, still it does not appear. Now will try to delete all existing related .jar files & try to recompile.

Right now, using 'cdn' option and recompiling all, it works again. NOTE: had not deleted existing
.m2/repository/com/vaadin/vaadin-context-menu/2.0.0/vaadin-context-menu-2.0.0.jar, just changed from fetch to cdn + maven clean + maven install.

I recompiled it and now all works OK.
Thanks.

Again happens, without no changes, just usual recompilation... It fires open event, but no menu is shown.

The issue is not related to ContextMenu, you definitely have troubles with widgetset compilation or browser widgetset caching.

For more details, please refer to https://vaadin.com/docs/v8/framework/addons/addons-maven.html#addons.maven

I close the issue as not a bug.
