>                 URL: http://jira.jboss.com/jira/browse/JBSEAM-497
>             Project: JBoss Seam
>          Issue Type: Bug
>          Components: Core
>    Affects Versions: 1.1.0.BETA2
>            Reporter: Ryan Dewell
>         Assigned To: Gavin King
>             Fix For: 1.1.0.CR1

> This did not exist in 1.1.0 beta 1 or previous versions.  It appears to be related to the new per-view configuration file instead of monolithic pages.xml.  
> We have our own custom, restful, view handler on top Seam/JSF.  
> ----
> java.lang.NullPointerException
>         at org.jboss.seam.core.Pages.createPage(Pages.java:212)
>         at org.jboss.seam.core.Pages.getPage(Pages.java:201)
>         at org.jboss.seam.core.Pages.getConvertedParameters(Pages.java:363)

> Presumably this NPE can occur any time replaceExtension returns null.
> So a simple fix might be:
> ----
> InputStream stream = null;
> String replaced = replaceExtension(viewId, ".page.xml");
> if (replaced != null)
>    stream = Resources.getResourceAsStream( replaced.substring(1) );
> if (stream == null){
> [...... etc .... ]
> ----
