Description

The following script:

class Test {
    void setProperty(String name, value) {
        println "instanceSetProperty"
    }

    void myMeth() {
        println 'instanceMyMeth'
    }
}

Test.metaClass.setProperty = { String name, value ->
   println 'metaSetProperty'
}
Test.metaClass.myMeth = { ->
   println 'metaMyMeth'
}
Test test = new Test()
test.a = 'b'
test.myMeth()

yields:

instanceSetProperty
metaMyMeth

The setProperty method added via the metaclass is ignored.

I changed the fix version to 2.0 because 2.0 is thought to implement a MOP redesign and as long as this does not happen it is unlikely that we will find a good work around for this. It is a limitation of the current design
