It's due to fixed OGNL version which properly supports JavaBean Specifications now. You can revert to prior version of OGNL to keep the old behaviour. See those issues https://issues.apache.org/jira/browse/WW-3909 https://issues.apache.org/jira/browse/WW-4616 and here you have another one https://github.com/jkuhnert/ognl/pull/21 Regards -- Łukasz + 48 606 323 122 http://www.lenart.org.pl/ --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
