[jira] [Updated] (TAP5-1713) A property expression that generates a
list can not reference public static field
[ https://issues.apache.org/jira/browse/TAP5-1713?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Howard M. Lewis Ship updated TAP5-1713:
---------------------------------------
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.
