Hi It looks like a page processed by facelets, not by JSP.
Between 2.2.0-beta and 2.2.0 we did a change in c:forEach tag. The improvement is ok, but according to the stack trace I can see a problemn with the id generation. I recently fixed this issue: https://issues.apache.org/jira/browse/MYFACES-3853 It looks like something related. If the id generation is correct, c:forEach and c:if receive different ids. The old algorithm in c:forEach did not have an associated id. Could you please try with the latest snapshot available here? https://repository.apache.org/content/repositories/snapshots/org/apache/myfaces/core/ regards, Leonardo Uribe 2014-02-18 21:20 GMT-05:00 Najy Nicolas <najy.nico...@gmail.com>: > Hi, > > > I have a <c:if tag inside 3 nested for loops in a JSP file. > I get an error only when I add the <c:if to the JSP... > > I only got the error when I upgraded to "MyFaces 2.2.0".
