Hi everybody. I have this snippet:
class Test {
def foo() {
def download = true
if (download) download()
}
private download()
}
}
In runtime, Groovy complains with: "No signature of method: java.lang.Boolean.call()"
That's because Groovy try to find first the implicit .call() method in the download variable, instead to invoke the real method in the same class.
It's a bug or it's a feature? Thank you! :)

feature, please use this.download() then instead, or rename your local
variable.

Pretty easy! thank you! And, what about this?
def chat = ""
render contentType:"text/xml", enconding:"UTF8" {
chat {
hello("guys")
}
}
The builder fails because the chat variable takes precedence over the invokeMethod inside the builder...

foo {} is a shortcut for foo({}), thus same story. In that case you will
really have to change the name of your local variable.

Hey Bdrag, MrHaki writes a nice way to avoid my problem, just puttin "delegate." before the method call
