What error are you getting?
I just tested this in MVELSH and it works:
mvel$ map["outerKey"]["innerKey"]
OUT: innerValue

2007/7/24, Felipe Piccolini <[EMAIL PROTECTED]>:
Suppouse I have a Map attribute and one of the values is another Map...how
can I check a member of the inner Map?
class MyFact{
Map map;
public MyFact(){
this.map = new HashMap();
}
....setter and getter...
}
-- test --
MyFact myFact = new MyFact();
Map innerMap = new HashMap();
innerMap.put("innerKey", new String("InnerValue"));
Map map = new HashMap();
map.put("mapKey", innerMap);
myFact.setMap(map);
.... set the RuleBase and insert myFact as a fact for the WorkingMemory...
-------
Now... how should I write the rule to check the innerKey ??
rule "test InnerMap"
when
$mf: MyFact( map['mapKey']['innerKey'] == "InnerValue" ) //
doesnt work...
....
$mf: MyFact( map['mapKey'].this['innerKey'] == "InnerValue" )
// doesnt work...
$mf: MyFact( map['mapKey'].['innerKey'] == "InnerValue" ) // doesnt
work...
$mf: MyFact( $innerMap: map['mapKey'], $innerMap['innerKey'] ==
"InnerValue" ) // doesnt work...
$mf: MyFact( $innerMap: map['mapKey'] -> ($innerMap['innerKey']
== "InnerValue" )) // doesnt work...
Thanks.
