[rules-users] how to retract all documents created in the following scenario

[vadlam]

when

$emptyDocs:java.util.List(size>0) from collect ( Document( field1== null ||
== ( "" ) , field2 == null || == ( "") ) )

then

	     
    //insert an error
    Error fact0 = new Error();
    fact0.setErrorCode( "code1" );
    insert(fact0 );

for (int i=0; i < $emptyDocs.size(); i++){
	retract( $emptyDocs.get(i));
	}


end

when I do a validate on this, I get an error as below

unable to resolve method using strict-mode:
org.drools.spi.KnowledgeHelper.$emptyDocs()] [Near : {... for (int i=0; i <
$emptyDocs.size(); i++){ ....}] 


am I making a mistake somewhere ?
