org.jboss.seam.handledException results in error "The class 'org.jboss.seam.Namespace' does not have the property 'handledException'" when this variable is not present ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBSEAM-3077 URL: https://jira.jboss.org/jira/browse/JBSEAM-3077 Project: Seam Issue Type: Bug Reporter: Alex Savitsky This variable (org.jboss.seam.handledException) is normally defined by Seam when an unhandled exception is thrown, and is subsequently displayed on an error page. However, when user refreshes the error page, they would get an error "The class 'org.jboss.seam.Namespace' does not have the property 'handledException'", due to the way Seam evaluates expressions - "org.jboss.seam" evaluates to an instance of Namespace, and "org.jboss.seam.handledException" is interpreted as "property 'handledException' of an object 'org.jboss.seam'". What's worse, there's no way to prevent this error from appearing, as the usual way of checking for variable existence - "empty org.jboss.seam.handledException" wouldn't work here, as it never evaluates to null - it's either there, or throws an error if it's not.
