I am using GlassFish 3.1.2 and trying to use composite:insertFacet in a composite component, but the HTML Markup is not generated when using my CC.
The same code works fine when I use composite:renderFacet, but I want to understand why composite:insertFacet is not working in that example? and when to use each of them?
This is my login.xhtml file (the Composite component implementation, the "heading" facet is the issue):

I tried to figure out the reason from the Component Tree, but I was more confused as the insertFacet appears, here is a the section from the Component Tree when using insertFacet:
<UIOutput id="j_idt7" inView="true" rendered="true" transient="false">
<UINamingContainer id="j_idt8" inView="true" rendered="true" transient="false">
error
<HtmlMessages globalOnly="false" id="j_idt10" inView="true" layout="table" redisplay="true" rendered="true" showDetail="false" showSummary="true" styleClass="error" tooltip="false" transient="false"/>

The <cc:insertFacet> is not intented for the composite itself, but for composite's child which in turn expects a facet which needs to be provided externally.
E.g. a <h:dataTable> which supports a <f:facet name="header"> (poor composite example, but it's just to give the idea):
<cc:implementation>
<h:dataTable>
<cc:insertFacet name="header">
Which is to be used as
<my:composite>
<f:facet name="header">
This has exactly the same effect as doing as below without a composite
<h:dataTable>
<f:facet name="header">
The <cc:insertFacet> is indeed used very rarely.
The <cc:renderFacet> is intented for the composite implementation itself and basically achieves the same as <ui:define>/<ui:insert> in templates and tagfiles.
