Issue

If I try a simple Drools rule with conditions on date type and uses conditional OR (||) I get the following error. If I change || to && it works fine.

Condition
$container: DateContainer( date >= "15-Oct-2013" || date <= "01-Oct-2013" )

Error
Unable to Analyse Expression date >= "15-Oct-2013" || date <= "01-Oct-2013":
[Error: Comparison operation requires compatible types. Found class java.util.Date and class java.lang.String]
[Near :
{... date >= "15-Oct-2013" || date <= "01-Oct-2013" ....}
