Smith, Jr. commented on MYFACES-3631: ----------------------------------------------- In the past, I used MyFaces Core 2.1.8 and 2.1.9, and I experienced some messages in server log that mentioned duplicated IDs after AJAX request/response. Anyway, I am now using MyFaces Core 2.1.10 (since I am using TomEE 1.5.1 and 1.5.2 SNAPSHOT), and I don't see 'duplicated IDs' exception/errors any longer in my server log(s). > Malformed Ajax XML Response with duplicated IDs > ----------------------------------------------- > > Key: MYFACES-3631 > URL: https://issues.apache.org/jira/browse/MYFACES-3631 > Project: MyFaces Core > Issue Type: Bug > Components: General > Affects Versions: 2.0.9, 2.0.15 > Reporter: Michael Moossen > Assignee: Leonardo Uribe > Priority: Minor > Fix For: 2.0.16, 2.1.10 > > > code to reproduce: > {code:xml} > > "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> > xmlns:h="http://java.sun.com/jsf/html" > xmlns:a4j="http://richfaces.org/a4j" > xmlns:c="http://java.sun.com/jsp/jstl/core" > xmlns:rich="http://richfaces.org/rich" > > Test > >
