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 /ConsultaLancamentos page and select the posting option, the following error occurs:

I'm using OmniFaces to redirect the error. It says either it will display the error page but it does not display in that case and if I enter the link through the browser the error does not occur, ie it is only displayed when it is selected from the menu.
