Hi,
The rendering of Section Frames is not hardcoded in the theme rendering
engine at all. In fact it is defined in:
nuxeo-theme-jsf/src/main/resources/OSGI-INF/nxthemes-jsf-contrib.xml
<extension target="org.nuxeo.theme.services.ThemeService" point="views">
...
<view name="section frame">
<element-type>section</element-type>
<format-type>widget</format-type>
<template>nxthemes/jsf/widgets/section-frame.xml</template>
</view>
</extension>
It is possible to register custom views for a specific elements (page,
section, ...) and also you can register new rendering engines, this is
all done in XML, not in Java.
I'm working on adding new parameters for the different template engines
(JSF, freemarker, ..), it will look like:
<view name="section frame">
<template-engine>jsf-facelets</template-engine>
<element-type>section</element-type>
<format-type>widget</format-type>
<template>nxthemes/jsf/widgets/section-frame.xml</template>
</view>
