[jbossseam-issues] [JBoss JIRA] Commented: (JBSEAM-497) NPE in Pages.createPage
[ http://jira.jboss.com/jira/browse/JBSEAM-497?page=comments#action_12346951 ]
Gavin King commented on JBSEAM-497:
-----------------------------------
But how can your view id not have a period in it? Your view handler uses view ids with no
period?
NPE in Pages.createPage
-----------------------
Key: JBSEAM-497
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
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.

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 .... ]
