pass all message in map()

how can i pass all message,from all() To map()...
in this case it gives error : $$segment$fail]
it works correctly when i pass it 1 message
```javascript
ASQ()
 .all(
function(done){done([1,2]);}
,
function(done){done([3,4]);}
    )//end all
  .map(function(item1,item2,mapdone){
 console.log(item1);
 console.log(item2);

        })
```
