[jira] [Updated] (GROOVY-4610) GroovyInterceptable (AOP) not working with closures

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

     [ https://issues.apache.org/jira/browse/GROOVY-4610?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Eric Milles updated GROOVY-4610:
--------------------------------
    Description: 
I've got a grails app with service classes that implement {{GroovyInterceptable}}: 
{code:groovy}
class customerSerrvice implements GroovyInterceptable { 
    private List<Customer> customers 
    def invokeMethod(String name, args) { 
        log.debug "=======>INVOKING method [$name] with args:$args" 
    } 
    void foo() { 
        customers.each { doSomething(it) } 
    } 
    void doSomething(Customer cust) {
        log.debug "doSomething invoked with $cust"
    } 
} 
{code}

If I call foo() or doSomething() *directly* from another class, the invokeMethod gets called like it is supposed to. However, when foo() calls doSomething(), that call is not intercepted in invokeMethod. 

If I change from   
{code:groovy}
customers.each { doSomething(it) }
{code}
  to   
{code:groovy}
for(Customer cust: customers) { doSomething(cust) }
{code}
then the invokeMethod gets called just fine. 

There appears to be an ExpandoMetaClass bug that prevents closures and GroovyInterceptable from working together.

  was:
I've got a grails app with Service classes that inherit from Groovy's GroovyInterceptable: 
[code] 
    class customerSerrvice implements GroovyInterceptable { 

    private List<Customer> customers 

    def invokeMethod(String name, args) { 
        log.debug "=======>INVOKING method [$name] with args:$args" 
    } 

    void foo() { 
        customers.each { doSomething(it) } 
    } 

    void doSomething(Customer cust) { log.debug "doSomething invoked with $cust" } 

    } 

[/code] 

If I call foo() or doSomething() **directly** from another class, the invokeMethod gets called like it is supposed to. However, when foo() calls doSomething(), that call is not intercepted in invokeMethod. 

If I change from   

`customers.each { doSomething(it) }`   

to   
`for(Customer cust: customers) { doSomething(cust) }`   

then the invokeMethod gets called just fine. 

There appears to be an ExpandoMetaClass bug that prevents closures and GroovyInterceptable from working together.
