Issue with page navigation

[hr.stoyanov]

Hi all,

In the attached code Errai 4 (latest from github) seem to not instantiate the default Home page and page graph seems empty. Any idea why? I suspect something is wrong with how the navigation panel is initialized, but it all look good in Chrome inspector. If I try to force the page to show up:

@AfterInitialization

    private void afterInitialization() {

        RestClient.setApplicationRoot("/rest");

        Body body = getDocument().getBody();

        body.appendChild(topNavigationBar.getElement());

        body.appendChild(mobileNavigationBar.getElement());

        navigationPanel.getElement().setId("pageContainer");

        navigationPanel.getElement().addClassName("uk-container uk-container-expand");

        //Effectively, adding the nav panel as last element in the body.

        RootPanel.get().add(navigationPanel);

         //force Home page to show up

        home.go();

    }

...I get this:

========================

Exception: org.jboss.errai.ui.nav.client.local.api.PageNotFoundException: There is no page of type com.recres.web.gwt.client.home.Home in the navigation graph.

ConsoleLogger.java:32 Error: org.jboss.errai.ui.nav.client.local.api.PageNotFoundException: There is no page of type com.recres.web.gwt.client.home.Home in the navigation graph.

Hi Hristo,

An empty page graphs means Errai is not seeing your pages at compile time. If you're not already, try compiling with strict mode so that you can see if any of your types are being ignored.

Hi Max,

In the Chrome source tab I can see the source for Home.java, even put breakpoints in it. So, source maps are loaded?

One thing I do is to skip all GWT Java classes when created the war, since I don't they are needed?

Also take a look at my beans.xml file.

I will try to send an easy to reproduce sample today...

Hi Hristo,

The NavigationGraphGenerator uses a class scanner to find @Pages, so you will need to compile class files.

Max, I found what is causing this and filed an issue:
