Paul King updated GROOVY-9603:
------------------------------
Affects Version/s: 2.5.12
> Assignment of Map literal to Map element fails to compile (static)
> ------------------------------------------------------------------
>
> Key: GROOVY-9603
> URL: https://issues.apache.org/jira/browse/GROOVY-9603
> Project: Groovy
> Issue Type: Bug
> Components: Static compilation, Static Type Checker
> Affects Versions: 3.0.3, 3.0.4, 2.5.12
> Reporter: Jochen Eddelbuettel
> Assignee: Eric Milles
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Declare a Map<String,Object>. When trying to put a map literal into that map,
> assignments in property style (map.key = ...) and subscript style (map[key] =
> ...) fail with
> *[Static type checking] - No such property: ... for class: java.lang.Object*
> First assigning to a local variable gives no such problems. If the Map were
> to contain objects of a specific type, coercion from map to that particular
> type would make sense. This coercion from Map to Object makes to sense. A Map
> is an Object and should simply become the new value for that particular key,
> which is just what is happening with regular compilation.
> Same for Map<String,?> and Map<String,? extends Object
> {code:groovy}
> @groovy.transform.CompileStatic
> def updateMap(Map<String,Object> map) {
> def innerMap = [ foo: "bar", bar: "foo" ]
> // No problem on this assignment
> map.someProp = innerMap
> assert map.someProp["foo"] == "bar"
> // The next three lines should all be equivalent
> // but the 2nd and 3rd don't CompileStatic
> map.put("someProp", [ abc: "efg" ])
> map["someProp"] = [ abc: "hij" ]
> map.someProp = [ abc: "klm" ]
> assert map.someProp["abc"] == "klm"
> }
> {code}
