Facts with event roles in process constraints cause exception
-------------------------------------------------------------
Key: JBRULES-2433
URL: https://jira.jboss.org/jira/browse/JBRULES-2433
Project: Drools
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: Paul Borlin
Assignee: Mark Proctor
When the following conditions are met, a runtime exception is thrown when the following
said type is inserted into working memory:
1. A ruleflow and rule definition are asserted into the knowledgebase
2. The rule definition declares a type as being an "event". (declare myType
@role( event ) @timestamp( value ) end )
3. The ruleflow references that type in a constraint.
4. A rule in the rule definition has a LHS constraint that references that type as an
event (i.e., code such as "over window:time( 12M )" is used)
Attached is a JUnit test that reproduces issue. The following stack trace is the result:
java.lang.ClassCastException: org.drools.common.DefaultFactHandle cannot be cast to
org.drools.common.EventFactHandle

I will work on this now, but I noticed a workaround: load your rules file before your flow
file into the builder.

Kris Verlaenen commented on JBRULES-2433:
-----------------------------------------
Actually, in this case, both your rules and ruleflow should share the same event
definition. It is however currently not possible to define something as an event in a
ruleflow file, you should do that in a separate drl file that accompanies the ruleflow and
defines the event. We usually recommend people to use a *.package file to contain common
definitions like imports, functions etc. that can be shared across rule files, but this is
no different when combining rules and ruleflows. I suggest you create a .package file
that contains the event definition (and possibly other shared stuff). You need to load
this before loading your other rules or ruleflows that depend on this.
It is of course possible to take your current rule file and see that as the package file,
containing not only your common definitions but also some dedicated rules. That's the
reason why loading the rules before the process should also fix this issue in this
situation.

-----------------------------------
Component/s: drools-compiler
drools-core
Fix Version/s: 5.1.0.M2
Affects Version/s: 5.1.0.M1
Following up on Kris' comments, I made sure the latest version is raising a proper
error message indicating that the event type was not previously declared as event. We need
to reinforce the requirement to have all type declarations and shared assets loaded before
a ruleflow that uses them is loaded.
