             Summary: The "from" CE does not manage @events correctly
                 Key: JBRULES-3637
                 URL: https://issues.jboss.org/browse/JBRULES-3637
             Project: Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: drools-core (fusion)
    Affects Versions: 5.4.0.Final
            Reporter: Davide Sottara
            Assignee: Edson Tirelli
            Priority: Critical
             Fix For: 5.5.0.Beta1


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.
