Paul King closed GROOVY-6888.
-----------------------------
> Static type checking fails if I change the closure input parameter name
> -----------------------------------------------------------------------
>
> Key: GROOVY-6888
> URL: https://issues.apache.org/jira/browse/GROOVY-6888
> Project: Groovy
> Issue Type: Bug
> Components: Static Type Checker
> Affects Versions: 2.3.3, 2.4.0-beta-1, 2.4.0-rc-1
> Reporter: Mauro Molinari
> Assignee: Paul King
> Priority: Major
> Fix For: 2.4.14
>
>
> Consider the following:
> {code}
> @TypeChecked
> class A {
> @Bindable
> String foo
>
> static void main(String[] args) {
> A a = new A()
> a.foo = 'old'
> a.addPropertyChangeListener('foo') { event ->
> println 'foo changed: ' + event.oldValue + ' -> ' +
> event.newValue
> }
> a.foo = 'new'
> }
> }
> {code}
> The Groovy compiler fails:
> bq. [Static type checking] - No such property: oldValue for class:
> java.lang.Object
> This is unexpected, because if I leave the {{event}} naming of the closure
> input parameter and use {{it.oldValue}}/{{it.newValue}} the static type
> checking succeeds (as it should).
