Navigation Bug

[egoosen]

Hi Guys,

I've just noticed a strange bug in my application wrt navigation.
The navigation on a particular page doesn't work when I'm logged into my app, but it works fine when I'm not logged in.
Here's my navigation rule in category.page.xml:

<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://jboss.com/products/seam/pages"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.1.xsd">

     <param name="categoryId" value="#{categoryHome.categoryId}" />
     
     <navigation evaluate="#{categoryHome.childCategories}">
          <rule if-outcome="0">
               <redirect view-id="/products.xhtml">
                    <param name="categoryId" value="#{categoryHome.categoryId}" />
               </redirect>
          </rule>
     </navigation>
     <!--
     <navigation>
          <rule if="#{empty categoryHome.childCategories}">
               <redirect view-id="/products.xhtml">
                    <param name="categoryId" value="#{categoryHome.categoryId}" />
               </redirect>
          </rule>
     </navigation>
     this option below didn't work at all
<navigation>
          <rule>
               <redirect view-id="#{categoryHome.getViewId()}">
                    <param name="categoryId" value="#{categoryHome.categoryId}" />
               </redirect>
          </rule>
     </navigation>
     -->

</page>

As you can see the one navigation rule is commented out, neither of them work when I'm logged in. Very strange?

As a workaround I created a method on my CategoryHome object to return the view-id, but that didn't work either.

I got this error:

The page isn't redirecting properly

Has anyone experienced this, and if so, how can I fix it, or what workaround can you suggest?

Regards,
Enrico

Created this workaround in the mean time:

<s:link action="#{categoryHome.getViewId()}" value="#{subCategory.name}">
     <f:param name="categoryId" value="#{subCategory.id}"/>
 </s:link>

public String getViewId(){
          if (getChildCategories().isEmpty()){
               return "/products.xhtml";
          } else {
               return "/category.xhtml";
          }
     }

I have this workaround for you, which avoids having another component just for redirection purposes:

<action execute="#{categoryHome.childCategories}" />
<navigation>
     <rule if-outcome="0">
          <redirect view-id="/products.xhtml">
               <param name="categoryId" value="#{categoryHome.categoryId}" />
          </redirect>
     </rule>
        <!-- if-outcome is not 0 -->
     <rule>
          <!--do something else -->
     </rule>
</navigation>

There is not much documentation on navigation in the official seam doc. It would seem like this would work but doesn't for me as well (I am using 2.1.1.GA):

<navigation evaluate="#{categoryHome.childCategories}">
     <rule if-outcome="0">
          <redirect view-id="/products.xhtml">
               <param name="categoryId" value="#{categoryHome.categoryId}" />
          </redirect>
     </rule>
</navigation>

Let me know if you find something better!
