Don't forget to tell the ReactorLoader interceptor to use this custom factory by specifying the ReactorFactoryClassPath property.

Example:
// Reactor ORM
{ class="coldbox.system.orm.reactor.ReactorLoader",
properties = {
ReactorFactoryClassPath = "#appMapping#/model/reactor/reactorFactory",
dsnAlias = "myDSN",
pathToConfigXML = "config/Reactor.xml.cfm",
project = "myProject",
mapping = "/#appMapping#/model/reactor",
mode = "production"
}
}
