-------------------------------------------
Summary: 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: 3.0.4, 3.0.3
Reporter: Jochen Eddelbuettel
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}
