Hi

I'm playing around with creating an error page and have run into a little problem.
My aim is to create an error page which displays as much information as possible.

I've used the messages.xhtml page from the wiki for inspiration.

In pages.xml I redirect all errors to an error.xhtml page.

I have a page with a page action which executes a method that creates a NPE (errorBacking is EVENT scoped).

<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-2.0.xsd">
          
     <action execute="#{errorBacking.createNpe}"/>
     
</page> 

If I have the following in error.xhtml:

<s:fragment rendered="#{! empty org.jboss.seam.caughtException}">
<pre>
<ui:repeat value="#{org.jboss.seam.handledException.stackTrace}" var="stackElement">
        #{stackElement}
</ui:repeat>
</pre>
</s:fragment>

I get this error:

SEVERE: Error Rendering View[/_errorPages/error.xhtml]
javax.faces.FacesException: javax.el.PropertyNotFoundException: /_errorPages/error.xhtml @17,66 rendered="#{! empty org.jboss.seam.caughtException}": Property 'caughtException' is not found on type: org.jboss.seam.Namespace

Looking in Conversations.java it looks that the org.jboss.seam.caughtException is set if there is an active conversation (or something similar).

Also ge the above error for the below xhtml if I access the error page without there being a handled exception:

<s:fragment rendered="#{! empty org.jboss.seam.handledException}">
<pre>
Top level exception : #{org.jboss.seam.handledException.class.name}: #{org.jboss.seam.handledException.message}
=================================================================================================

<ui:repeat value="#{org.jboss.seam.handledException.stackTrace}" var="stackElement">
        #{stackElement}
</ui:repeat>
</pre>

</s:fragment>

Seems like the EL resloves org.jboss.seam to a Namespace object.

Is the naming of components with dots in the name a good idea?

Help

Thanks,

Micke
