It seems that only grails.serverURL and grails.path are recognized as per environment configrautions. bla and foo are ignored and could not be used in application Anyone could solves this and provide a way to get bla and foo configured per environment?

environments {
    production {
        grails.serverURL = "http://alpha.foo.de"
        grails.path = ""
        bla = "text"
        foo= "word"
    }
    test {
        grails.serverURL = "http://test.foo.de"
        grails.path = ""
        bla = "othertext"
        foo= "otherword"
    }
}
