[S2] OGNL and enum

[Pierre Thibaudeau <pi...@gmail.com>]

It is possible to refer to an enum value within OGNL:
%{@com.myapp.Planets@MARS}

But how can I refer to the collection of all the values of an enum?  In
Java, that would be:  com.myapp.Planets.values()
With OGNL, I tried the following without success:
%{@com.myapp.Planets@values()}
%{@com.myapp.Planets@values}
%{@com.myapp.Planets.values()}

One option that would work:
%{{@com.myapp.Planets@MERCURY, @com.myapp.Planets@VENUS,
@com.myapp.Planets@EARTH, etc.}}

but that defeats the point, doesn't it?

Ah, I didn't know that!

Thanks for the advice!

You'll need to enable OGNL's access to static methods.

struts.ognl.allowStaticMethodAccess=true

Otherwise your approach is fine. 

I try  not to use this myself.  Instead I expose a property that 
provides the values so it can sort, lookup I81N text, and minimize 
dependencies on OGNL-specific syntax.
