Question

I’d like to redirect my app flow by using the ‘faces-config’ xml file resource like as the “redirect” tag.

So, here is my “faces” xml:

<navigation-rule>
  <from-view-id>/index.xhtml</from-view-id>
  <navigation-case>
    <from-outcome>falha_etapa_1</from-outcome>
    <to-view-id>/index.xhtml</to-view-id>
    <redirect>
      <redirect-param>
        <name>msg</name>
        <value>-1</value>
      </redirect-param>
    </redirect>
  </navigation-case>
</navigation-rule>    

And here, my jsf page:

<h:form>
  <f:view>
    <p:outputLabel value="${param['msg']}" />
    and so on....

This print’s anything (blank)!!!!
Why could not print the parameter value?
Thanks!

Answer 1

Change ${param['msg']} to #{param['msg']}

<p:outputLabel value="#{param['msg']}" />
