[rules-users] Static Imports

Hi, Are static imports as shown below allowed in rule files? It is giving me a parse exception. package mypackage; dialect "mvel" import mypackage.CreditTransferTransactionInformation10; import static mypackage.ValidationHelper.invalidate; global java.util.Set accountNumbers; rule "Check debtor account number is not null" salience -1 when $c : CreditTransferTransactionInformation10 ( eval( dbtrAcct.?id.?othr.?id == null ) ) then invalidate($c, "PG003", "Account number is absent"); drools.halt(); end Ta Meeraj
