Enum constants in webflow expression language?

[MartinCz]

Hi.

Is it possible to use enum constant values in the web flow expression language?
I would like to use something like this:

<evaluate expression="myVariable.myMethod(mypackage.MyClass.MyEnum.HELLO_WORLD)" />

This does not seem to work for me. Says it cannot be resolved.

So I am wondering, is this possible? Or what am I doing wrong?

Thank you!

If you're using OGNL for your expression parser, there's a special way to invoke this.

The pattern is:

@package.name.enum.class.name@ENUM_NAME

So, for your case, you would use:
@mypackage.MyClass.MyEnum@HELLO_WORLD

Not sure how to do this with other expression parsers, though.

To do this in Spring EL, you would use:

T(mypackage.MyClass$MyEnum).HELLO_WORLD

Using "$" to access an inner type isn't in the reference docs, I just figured it out using JUnit and some inspired guesswork.

Thanks for the response, Andrew. I was stuck on this as well and the example you provided solved my problem.
