FactTemplate Property Access leads to RuleBuilder Exception
-----------------------------------------------------------
Key: JBRULES-1438
URL: http://jira.jboss.com/jira/browse/JBRULES-1438
Project: JBoss Drools
Issue Type: Bug
Security Level: Public (Everyone can see)

Reporter: greywind
Attachments: EntityTest.drl
The only thing I do is to add the attached drl to a Package and do get the following
exception:

As you can see the Property exists and from the original attachment you can also see that
the property can be accessed in the rule itself....

---------------------------------------
I'm just looking into your drl at the momen, will get back to you.
On the second error:
System.out.println("Found: " + $s.InstrumentName);
That isn't allowed, this is one of the reasons why we haven't made fact templates
public knowledge. Java or MVEL see fact templates as anything special, so you have to just
treat it like a normal pojo of the FactTemplate interface:
s.getValue( "InstrumentName" )
