Eric Milles updated GROOVY-8146:
--------------------------------
Language: groovy
> Callable properties of closure delegate cannot be called implicitly
> -------------------------------------------------------------------
>
> Key: GROOVY-8146
> URL: https://issues.apache.org/jira/browse/GROOVY-8146
> Project: Groovy
> Issue Type: Improvement
> Components: groovy-runtime
> Affects Versions: 2.5.0-alpha-1
> Reporter: David Attia
> Priority: Major
>
> Where a closure's delegate has a property with a call method, the method
> cannot be called inline.
> {noformat}
> class DelegateMember {
> void call(@DelegatesTo(DelegateMember) Closure closure) {
> closure.delegate = this
> closure.call()
> }
>
> void sayHello() { println 'hello' }
> }
> class Delegate {
> DelegateMember delegateMember = new DelegateMember()
> }
> void callAndDelegate(@DelegatesTo(Delegate) Closure closure) {
> closure.delegate = new Delegate()
> closure.call()
> }
> callAndDelegate {
> delegateMember { // intended get and call of delegateMember
> sayHello()
> }
> }
> {noformat}
> In the above example, I'm hoping for the commented line to call the synthetic
> getter for delegateMember and to then call it with the closure parameter
> (code block).
> My IDE (IntelliJ IDEA 2016.2.2) interprets this code in the way I hoped the
> runtime would (asking to go to the declaration of sayHello from the call
> within the closure takes me to the declaration of the sayHello method), but
> execution fails with message:
> {noformat}
> Caught: groovy.lang.MissingMethodException: No signature of method:
> scratch_groovy.delegateMember() is applicable for argument types:
> (scratch_groovy$_run_closure1_closure2) values:
> [scratch_groovy$_run_closure1_closure2@6b46a226]
> groovy.lang.MissingMethodException: No signature of method:
> scratch_groovy.delegateMember() is applicable for argument types:
