I have the following menu:

    <h:form>
    <p:menubar style="margin-top: -20px; margin-bottom: 20px">
        <p:submenu label="Cadastros">
            <p:menuitem value="Pessoa" />
            <p:menuitem value="Lançamento"
                action="/CadastroLancamentos?faces-redirect=true" />
        </p:submenu>
        <p:submenu label="Consultas">
            <p:menuitem value="Pessoas" />
            <p:menuitem value="Lançamentos"
                action="/ConsultaLancamentos?faces-redirect=true" />
        </p:submenu>
        <p:submenu label="Sistema">
            <p:menuitem value="Sair" action="#{loginBean.logout}" />
        </p:submenu>
    </p:menubar>
</h:form>

When I’m on the page /ConsultaLancamentos and select the launch registration option, the following error occurs:

I’m using Omnifaces to redirect the error. It says either will display the error page but does not display in this case and if I enter the link by the browser the error does not occur, ie it is being displayed only when it is selected in the menu.

Post page code Queries.

Should this bar exist before the page name? Test without, please

Apparently the problem occurs in treating exceptions with the configuration of the FullAjaxExceptionHandlerFactory. After commenting on the code: <exception-handler-factory>
 org.omnifaces.exceptionhandler.FullAjaxExceptionHandlerFactory
 </exception-handler-factory> Navigation returned to normal without any changes. The strange thing is that when it occurs on the error page Omnifaces informs me that the problem is occurring before the error page call.

@igorventurelli With the removal of the bar the behavior is equal. With omnifaces gives problem and without it redirects normal.
