[jboss-jira] [JBoss JIRA] Commented: (AS7-1485) Packaging Xerces in war causes JSF ClassCastException on SAXParserFactory

[Marek Novotny (JIRA)]

    [ https://issues.jboss.org/browse/AS7-1485?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12629375#comment-12629375 ] 

Marek Novotny commented on AS7-1485:
------------------------------------

it looks like tag library loading from WEB-INF/lib is broken by patch. This is done by getting faces-config.xml from jboss-seam-ui.jar, where are custom Seam JSF components.
