Grails External Configuration. Can't access to external variable. Getting always [:] - grails

Question

I can't have my 'folder' external variable working. Always I'm getting [:].
I'm developing on Grails under Windows (this is why the external configuration file looks like file:C:\path\to/file).
I'm using external configuration in another project without problems, in the same way that I'm showing below.
I have this:
Config.groovy:
environments {
development {
grails.config.locations = [ "file:${userHome}/.grails/${appName}-config.groovy" ]
}
}
myApp-config.groovy:
stats.feed.wsdl.folder = '/static'
Controller and Service:
class WsdlController {
def wsdlService
def index = {
wsdlService.getEventsSchedule()
}
}
class WsdlService {
def grailsApplication
def getEventsSchedule = {
println "Locations: ${grailsApplication.config.grails.config.locations}"
println "Folder: ${grailsApplication.config.stats.feed.wsdl.folder}"
}
}
Console:
Locations: [file:C:\Users\myUser/.grails/myApp-config.groovy]
Folder: [:]
Any clue?
Thanks!
Updated!
This is the whole myApp-config.groovy:
println 'Start'
stats.feed.wsdl.folder = "/stats"
println 1
stats.feed.wsdl.folder.events = "${stats.feed.wsdl.folder}/events"
println 2
stats.feed.wsdl.folder.teams = "${stats.feed.wsdl.folder}/teams"
println 'End'
This is not working, the console shows:
Start
1
But if I change the variable names, it works.
println 'Start'
stats.feed.wsdl.folder = "${playcall.static.resources.folder}/stats"
println 1
stats.feed.wsdl.events.folder = "${stats.feed.wsdl.folder}/events"
println 2
stats.feed.wsdl.teams.folder = "${stats.feed.wsdl.folder}/teams"
println 'End'
Console:
Start
1
2
End

You create a property and declared this as a string:
stats.feed.wsdl.folder = "/stats"
In that way you isnt't able to add subproperties. So, to keep something close to what you want, you can do this:
stats.feed.wsdl.folder.base = "/stats"
stats.feed.wsdl.folder.events = "${stats.feed.wsdl.folder.base}/events"
stats.feed.wsdl.folder.teams = "${stats.feed.wsdl.folder.base}/teams"
