[jbossseam-issues] [JBoss JIRA] Created: (JBSEAM-1231) Cannot pass empty parameters in *.page.xml
Cannot pass empty parameters in *.page.xml
------------------------------------------
Key: JBSEAM-1231
URL: http://jira.jboss.com/jira/browse/JBSEAM-1231
Project: JBoss Seam
Issue Type: Bug
Affects Versions: 1.2.1.GA
Reporter: Alan Fehr
When passing an empty parameter in a redirect in a *.page.xml, I get a
NullPointerException. Empty parameters work when used on pages (with s:link and
<f:param name="paramName" />) but when used as mentioned I get:
2007-04-23 16:31:13,437 ERROR
[org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/zdb].[Faces Servlet]]
Servlet.service() for servlet Faces Servlet threw exception
