>             Project: Groovy
>          Issue Type: Bug
>          Components: Static Type Checker
>            Reporter: Eric Milles
>            Assignee: Eric Milles
>            Priority: Major
>             Fix For: 5.0.5

> Consider the following:
> {code:groovy}
> class Pogo {
>   List<Long> getList() {
>   }
>   void setList(List<Long> longs) {
>   }
> }
> @TypeChecked m(List<Pogo> pogos) {
>   for (pogo in pogos) {
>     pogo.list = [] // Cannot assign java.util.ArrayList<java.lang.Object> to: java.util.List<java.lang.Long>
>     def item = 42L
>     pogo.list.add(item)
>   }
> }
> {code}
> When the property expression "pogo.list" is backed by getter and setter (not property), the addition of a dynamic-typed item "def item = ..." causes an error on the init line "pogo.list = []".
> Changing the the of {{item}} to {{Long}} and the error goes away.
