Subject [jira] Commented: (STR-3191) Sufficently filter HTML tag attribute names and values
Date Wed, 23 Sep 2009 18:26:48 GMT

    [ https://issues.apache.org/struts/browse/STR-3191?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=46831#action_46831
] 

Florian Weimer commented on STR-3191:
-------------------------------------

Code subclasses the struts tag classes, overriding methods which then inject network-supplied
data into strings which are passed  to the prepareAttribute() method.

IIRC, an example is LinkTag from Portal Struts Bridges:

http://svn.apache.org/viewvc/struts/struts1/trunk/taglib/src/main/java/org/apache/struts/taglib/html/LinkTag.java?revision=557865&view=markup
