[jboss-jira] [JBoss JIRA] (WFLY-6267) JSTL will fail with tags using x:out nested in a x:forEach

[Matthew Casperson (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-6267?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Matthew Casperson updated WFLY-6267:
------------------------------------
    Description: 
See https://github.com/mcasperson/wildfly_jstl_bug/

What happens is you have a x:forEach in a JSP page. Inside this x:forEach you call a tag that itself has a x:forEach. The variable created by the second x:forEach is inaccessible to any nested x:out elements.

This happens because the x:out pageContext is actually linked to the pageContext from the jsp page, which doesn't hold any variables created by the x:whatever elements in the tag file.

See https://github.com/mcasperson/wildfly_jstl_bug/blob/master/src/main/webapp/index.jsp and https://github.com/mcasperson/wildfly_jstl_bug/blob/master/src/main/webapp/WEB-INF/tags/my.tag for more details.
