Mark Proctor commented on JBRULES-3637:
---------------------------------------

There is a workaround for this, re-resolve the fact back form the WM.
{code}
rule "Check"
when
$e2 : MyEvent( id == 2 )
$b1 : MyBean( id == 99, $ev : event )
$t : MyEvent() from $ev
MyEvent( this == $t, this before $e2 )
{code}

> If an event type (i.e. an instance of a class marked with @role(event)) is returned by a "from" node, it is not wrapped by an EventFactHandle as expected, so e.g. any attempt to use temporal operators will fail. 
> See the test case below for an example
> The problem is in FromNode.java around line 200, where the new handles are created without passing an ObjectTypeConfiguration, leading to the default creation of a DefaultFactHandle.
> I wonder if it's possible to simply retrieve the ObjectTypeConf:
> workingMemory.getObjectTypeConfigurationRegistry().getObjectTypeConf( context.getEntryPoint(), object )
> and pass it to the handle factory method. 
> I tested it and it works for the test case below, but there may be other
> side-effects I'm not seeing.
