Paul King closed GROOVY-7004.
-----------------------------
> No such property error with a private constant
> ----------------------------------------------
>
> Key: GROOVY-7004
> URL: https://issues.apache.org/jira/browse/GROOVY-7004
> Project: Groovy
> Issue Type: Bug
> Components: Compiler
> Affects Versions: 2.3.6
> Reporter: Mauro Molinari
> Assignee: Eric Milles
> Priority: Major
>
> Consider the following Groovy classes:
> {code}
> package test2
> import groovy.beans.Bindable;
> import groovy.transform.CompileStatic;
> class MyBean {
> @Bindable
> String foo
> String bar
> }
> {code}
> {code}
> package test2
> import groovy.transform.CompileStatic
> import java.beans.PropertyChangeEvent
> class TestBase {
> private static final String CONSTANT = 'foo'
> MyBean mb = new MyBean()
> void doSomething() {
> mb.with {
> addPropertyChangeListener('foo') { PropertyChangeEvent
> event ->
> bar = (event.newValue == CONSTANT)? 'bar': null
> }
> foo = CONSTANT
> }
> }
> }
> {code}
> {code}
> package test2
> import groovy.transform.CompileStatic;
> class TestExt extends TestBase {
> static void main(String[] args) {
> TestBase b = new TestBase()
> b.doSomething()
> println b.mb.bar
>
> TestExt e = new TestExt()
> e.doSomething()
> println e.mb.bar
> }
> }
> {code}
> Run as a Groovy script. The output is this:
> {noformat}
> bar
> Caught: groovy.lang.MissingPropertyException: No such property: CONSTANT for
> class: test2.MyBean
> groovy.lang.MissingPropertyException: No such property: CONSTANT for class:
> test2.MyBean
> at
> test2.TestBase$_doSomething_closure1_closure2.doCall(TestBase.groovy:16)
> at com.sun.proxy.$Proxy4.propertyChange(Unknown Source)
> at java_beans_PropertyChangeSupport$firePropertyChange$0.call(Unknown
> Source)
> at test2.MyBean.firePropertyChange(MyBean.groovy)
> at test2.MyBean$firePropertyChange.callCurrent(Unknown Source)
> at test2.MyBean.setFoo(MyBean.groovy)
> at test2.MyBean.setProperty(MyBean.groovy)
> at test2.TestBase$_doSomething_closure1.doCall(TestBase.groovy:18)
> at test2.TestBase.doSomething(TestBase.groovy:14)
> at test2.TestBase$doSomething.call(Unknown Source)
> at test2.TestExt.main(TestExt.groovy:13)
> {noformat}
> If you then change the visibility of {{CONSTANT}} from private to protected,
> then the output is correct:
> {noformat}
> bar
> bar
> {noformat}
> It seems like the closure that implements the {{PropertyChangeListener}},
> when executed from {{TestExt}}, is searching for {{TestExt.CONSTANT}} first,
> and then for {{MyBean.CONSTANT}}, and not seeing it because of the private
> modifier. However, I would expect it to refer to {{TestBase.CONSTANT}} in any
> case...
