Description

Very difficult to identify exceptions that are thrown during processing of EL statements, since all information is swallowed without logging.

org.apache.myfaces.el.PropertyResolverImpl.getProperty catches a Throwable exception and creates a new EvaluationException

This is then caught by org.apache.myfaces.el.PropertyResolverImpl.getValue as a RuntimeException and then throws a new EvaluationException.

This is in turn caught by the org.apache.myfaces.el.ValueBindingImpl.getValue method Exception catch and another new EvaluationException is thown.

The error message on the UI is "Exception: javax.faces.el.EvaluationException: Cannot get value for expression '#

{erHandler.expectedReceipt.seqno}

'" which has lost all trace of the underlying exception.

Would be better to have the information from the underlying exception in the error message in the UI. If this is not practical, then a logged message would greatly facilitate debugging.
