According to the Fusion manual, "after" is used like this: $eventA : Foo(...) $eventB : Bar( this after[0ms,1h] $eventA )
provided Foo and Bar have @role(event). This works. But, given a class Wrapper( Foo foo ), the pattern combination Wrapper( $eventA : foo ) $eventB : Bar( this after[0ms,1h] $eventA ) results in a class cast exception at runtime, telling me that a Foo cannot be cast to a org.drools.common.EventFactHandle. Working around this by doing Wrapper( $foo: foo ) $eventA : Foo( this == $foo ) $eventB : Bar( this after[0ms,1h] $eventA ) solves the problem, but is this really necessary and intentional? (The documentation doesn't even hint at such a restriction.) -W
