Actually, I failed to figure out how to report an issue via that issue tracker.
Sorry I ran out of time for today.
One thing: I narrowed the problem down easily:
add a following wrapper component to the nav example:
basic-ezcomp/resources/navbutton/wrapper.xhtml
<?xml version='1.0' encoding='UTF-8' ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="
http://www.w3.org/1999/xhtml"
xmlns:ui="
http://java.sun.com/jsf/facelets"
xmlns:c="
http://java.sun.com/jsp/jstl/core"
xmlns:f="
http://java.sun.com/jsf/core"
xmlns:h="
http://java.sun.com/jsf/html"
xmlns:composite="
http://java.sun.com/jsf/composite"
xmlns:gc="
http://java.sun.com/jsf/composite/components"
xmlns:g="/GteeTagLibrary">
<body>
<composite:interface name="wrapper">
</composite:interface>
<composite:implementation>
above
<composite:renderUsingPageChildren/>
below
</composite:implementation>
</body>
</html>
then use it in the /basic-ezcomp/nav1.xhtml this way:
<h1> Page 1</h1>
<ez:wrapper>
<ez:nav act="#{navigation.goNav2}"/>
</ez:wrapper>
you'll get the mentioned exception (see below)
Now if you do the following:
<h1> Page 1</h1>
<ez:nav act="#{navigation.goNav2}"/>
<ez:wrapper>
<ez:nav act="#{navigation.goNav2}"/>
</ez:wrapper>
the problem disappears!
