Hi When you use ui:include, inside myfaces a new template context is created, and all template logic including template params are "isolated", which means params passed or earlier ui:define or ui:insert declarations will be ignored.
So it is expected ui:param definitions does not pass through ui:include, unless you define a ui:param inside ui:include and declare in a explicit way that this param will be used inside that template. Other option is use ui:decorate instead ui:include, so the same template context will be used to resolve your template. The issue related to this behavior is: https://issues.apache.org/jira/browse/MYFACES-2753 Trivial multi-level templating does not work if ui:include is used regards, Leonardo Uribe
