Description

So in my template,

context="[ foo, bar ]"

And in my code:

public static Foo FOO = Foo.FOO; // Foo is an enum type

This fails:

java.lang.IncompatibleClassChangeError

Expected non-static field com.example.pages.MyPage.FOO

Replacing the field with:

public Foo getFoo()

{ return Foo.FOO ; }

works. There's the workaround, anyway.
