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:
