Exception handling in pages.xml ignores EL expressions
------------------------------------------------------
Key: JBSEAM-2930
URL: http://jira.jboss.com/jira/browse/JBSEAM-2930
Project: Seam
Issue Type: Bug
Components: Framework
Affects Versions: 2.0.1.GA
Environment: JBOSS 4.2.2, Windows XP
Reporter: Wolfgang Chico Toepfer
When I try to catch and handle an exception by means of the exception tag in pages.xml,
the exception is not properly handled because the EL expression is not resolved.
<exception class="de.pta.exception.ValidationException">
<redirect view-id="#{emrNavigationManager.currentViewId}" />
</exception>
The same problem also occurs with the annotation alternative:
@Redirect(viewId="#{emrNavigationManager.currentViewId}")
public class ValidationException extends RuntimeException {
public ValidationException(String message) {
super(message);
}
}
Here's the log:
