[jira] [Resolved] (GROOVY-2641) Dynamically created closure handles delegate differently from statically created closure

["Eric Milles (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/GROOVY-2641?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Milles resolved GROOVY-2641.
---------------------------------
    Resolution: Information Provided

The default resolve strategy of Closure is OWNER_FIRST.  The dynamicClosure case is displaying this behavior.  When adding the following before calling dynamicClosure, the expected behavior is present:
{code:groovy}
dynamicClosure.setResolveStrategy(Closure.DELEGATE_FIRST)
{code}

> The following script executes two closures.  One is statically defined in class Test, 
> the other is returned by Test.makeClosure().  In each case the delegate of the
> Closure is set to be an instance of class Delegate, but in one case a call to
> method "foo()" appears to resolve to Test.foo(), while in the second it appears
> to resolve to Delegate.foo().
> I showed this to Dierk at the G2 conference in Reston, and he asked me to post
> it as a bug.
