> Hi,
> I found the following problem using Struts (2.5.20) based on OGNL (3.1.21) and same result forcing OGNL (3.1.25, as 3.2.x series seem to be not compatible with this version of Struts).
> The situation can be summarize  with the following 2 enums:
> {code:java}
> enum Normal { A, B; }
> enum Strange {A {}, B{}; } // mainly for implementing abstract method(s)
> {code}
> and the following expressions are:
> {noformat}
> @Normal@A==@Normal@A // true
> @Normal@A!=@Normal@A // false
> @Normal@A==@Normal@B // false
> @Normal@A!=@Normal@B // true{noformat}
> whereas the following expressions are:
> {noformat}
> @Strange@A==@Strange@A // true
> @Strange@A!=@Strange@A // false
> @Strange@A==@Strange@B // false (with warn log)
> @Strange@A!=@Strange@B // false (with warn log){noformat}
> and the origin of the wrong test value was discover activating WARN log level in Struts (using struts.devMode).
> Thanks,
> Patrice
