Yes, it is stronger. > In my case i try to compare two different enums: DocboxListColumn and > GenericListColumn, but they both implement interface ListColumn. > The chapter 1.8.2 of the EL spec (jsp-2_1-fr-spec-el.pdf) says that equals operator is applied as follows: If A or B is an enum, coerce both A and B to enum, apply operatorr BTW, if you really need to compare apples with oranges, you can convert one of them or both to strings. There is no string "concat" operator in EL, but there is support for "Composite expressions", such as “${firstName} ${lastName}” Best regards, Konstantin Kolinko --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
