Description

The following code will not compile:

class Account {
   String id
}
class GCAccount {
   List<Account> sfAccounts
}
class User {
   List<GCAccount> gcAccounts
}

@groovy.transform.CompileStatic
void foo() {
def accounts = (1..10).collect { new Account(id:"Id $it") }
def user = new User(gcAccounts:[new GCAccount(sfAccounts:accounts[0..2]),new GCAccount(sfAccounts:accounts[3..4])])
def ids = user.gcAccounts.sfAccounts.id.flatten()
println ids
}
foo()

The error is:

No such property: id for class: java.util.List <java.util.List>

indicating that the generic type inference is incomplete.
