[jira] [Commented] (WW-4105) Struts2 raise java.lang.ClassCastException when Result type is chain

    [ https://issues.apache.org/jira/browse/WW-4105?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13681950#comment-13681950 ] 

Lukasz Lenart commented on WW-4105:
-----------------------------------

Could you share you setup? Or prepare small maven based app which presents the bug?

I have tested with the Struts2 Showcase application (there is example how to use action chaining) and everything works like charm :-)
