[groovy-user] Change closures delegate results in no property exception

[Batman]

I’m trying to play around with Groovy closures. Here is what I have:

class WaitLoaderConstrains{

def methodMissing(String methodName, args) {
if(methodName == "wait")
{
def a = args[0] as Map
println "Author is " + a['name']
}
}
}

class Author {

def name1 = "author name"

static constraints = {
wait name: name1 , time: 123
}
}

def a = new Author()

a.constraints.delegate = new WaitLoaderConstrains()


a.constraints()

but this sadly throws the exception:

groovy.lang.MissingPropertyException: No such property: name1 for class:
Author
Possible solutions: name1
at Author$__clinit__closure1.doCall(Script1.groovy:17)
at Author$__clinit__closure1.doCall(Script1.groovy)
at Script1.run(Script1.groovy:26)

why the closure’s can’t access, name1 from the same Author class?


Is it a bug or I'm missing something here?

`constraints` is a static field, `name1` is not. If you made `name1`
to also be a static field, it would work.
