Description

See http://www.nabble.com/EMC-and-a-property-tf4956215.html

I have two classes A and B. A is enhanced with meta magic (EMC): a property and a method which should work on this property. B calls the meta method from A, though the property will not change whatever I try. Here's the code:

ExpandoMetaClass.enableGlobally()

class A {}

A.metaClass.status = 'empty'
A.metaClass.change =

{ println "status from A changed to: $it" status += it }

class B {
def getStatus() {
def a = new A();
a.change('filled')
println "status from A through B is: ${a.status}"
}
}

new B().status

The output is:

status from A changed to: filled
status from A through B is: empty

What I expect in the last line is a 'filled' instead of an 'empty'.
