[seam-issues] [JBoss JIRA] Commented: (JBSEAM-3355) SeamExpressionEvaluator gobbles up exceptions

SeamExpressionEvaluator gobbles up exceptions ---------------------------------------------- Key: JBSEAM-3355 URL: https://issues.jboss.org/browse/JBSEAM-3355 Project: Seam 2 Issue Type: Bug Affects Versions: 2.1.0.BETA1 Reporter: Wolfgang Schwendt Priority: Critical Fix For: 2.3.0.ALPHA Rev 8710 of org.jboss.seam.bpm.SeamExpressionEvaluator introduced a serious bug. If the invocation of the method expression (me.invoke(...)) throws an exception such as org.jboss.seam.security.AuthorizationException, the SeamExpressionEvaluator afterwards tries to evaluate the EL expression as a value expression. This of course results in a second exception thrown: PropertyNotFoundException. Consequently, the list "exceptions" has size > 2 (rather than just size==1), which results in SeamExpressionEvaluator throwing an ELException that does not wrap the exception which originally caused the method expression invocation to fail. The bug was introduced because, compared with earlier versions, the try/catch-blocks for the method expression and value expression evaluation were changed and are now wrong. This is serious because it breaks the handling of any application exception thrown while evaluating the EL method expression, such as AuthorizationException.
