JS Errors are not handled correctly

           Summary: JS Errors are not handled correctly
           Product: Cocoon 2
           Version: Current CVS 2.1
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: Flowscript
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: joerg.heinicke@gmx.de


When throwing an Error in JS as at
http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/src/blocks/authentication-fw/samples/flow/sample.js?annotate=1.5#81
or
http://cvs.apache.org/viewcvs.cgi/cocoon-2.1/src/blocks/forms/java/org/apache/cocoon/forms/flow/javascript/Form.js?annotate=1.18#167
you will only get an error message like
"file:/home/jheinicke/development/ERAK/erak/webapp/flow/authentication.js", line
81: Invalid JavaScript value of type org.mozilla.javascript.UniqueTag.

This means the file and line info are correctly provided, but not the error
message or the error itself. When viewing the call stack while remote debugging
the error object does still exist at
org.mozilla.javascript.continuations.ContinuationInterpreter.interpret(ContinuationInterpreter.java:1503),
so I guess somewhere there is the error.

Would be nice if someone familiar with our continuations code can have a look at it.
