I don' t think you need to build this on the BasicXMLResource, but
rather keep extending the NodeResource by overwriting the getNode() method.
Inside the getNode() method the method getResourceConfigProperty("src")
is called which is getting the path from
src/realms/from-scratch-realm-template/res-configs/my-global.xsl.yanel-rc
<yanel:property name="src" value="/app/xslt/global.xsl"/>
So I would suggest to introduce a new method called
getNode(String layoutVersion) which shall replace the getNode() method
and also a new resource type property for this new resource, for example
<yanel:property name="default-layout-version" value="2"/>
<yanel:property name="src" value="/appTEMPLATE_VERSION/xslt/global.xsl"/>
and the template version can be retrieved from the query string inside
the resource by
String layoutVersion = getRequest().getParameter("layout-version");
if (layoutVersion != null) {
getRequest().getSession().setAttribute("layout-version", layoutVersion)
} else {
if (getRequest().getSession().getAttribute("layout-version")) {
layoutVersion =
getRequest().getSession().getAttribute("layout-version");
} else {
layoutVersion = getResourceConfigProperty("default-layout-version")
}
}
