Also, is your Glassfish/Wildfly container using Mojarra as the JSF implementation? If nothing else, MyFaces could provide a configuration parameter which would ignore empty render type tag contents and continue onward. Do you mind submitting a patch to provide such behavior? was (Author: mkienenb): Would you mind reposting your question on dev@myfaces.apache.org so it can be discussed?

From what I can see the exception appears > to be thrown on elements which are used in another spot. If any of them are > empty they will throw the above exception. Wildfly/Glassfish does not have > the same behavior, so my assumption is they just ignore it. > Should the MyFaces code be modified to just continue on without the > exception, based on the reference implementation? I can quickly create > something if so, I just wanted to bring this up to the community at large > since I don't know the reasoning behind the difference of the implementations. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
