Subject [jira] [Commented] (WW-4479) Ognl can't access static field on enum
Date Thu, 19 Mar 2015 22:55:40 GMT

    [ https://issues.apache.org/jira/browse/WW-4479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14370284#comment-14370284

Jasper Rosenberg commented on WW-4479:
--------------------------------------

Yes, that stackoverflow post describes the bug.  It's a relatively easy to fix in OgnlRuntime.getStaticField()
 though.

> You can use an ognl expression to access a static field or an enum field, but you can't
access a static field on an enum.
> @com.myco.MyEnum@MY_STATIC_FIELD
> blows up with:
> Caused by: java.lang.IllegalArgumentException: No enum constant com.myco.MyEnum.MY_STATIC_FIELD
> OgnlRuntime.getStaticField() needs to check for both enum field name and static field
name for enums.
> This is particularly annoying now with ognl static method invocation deprecated.
