Edson Tirelli resolved JBRULES-1766.
------------------------------------
Fix Version/s: 5.0.0.M2
Resolution: Cannot Reproduce Bug
Assignee: Edson Tirelli (was: Mark Proctor)
Michael,
I was not able to reproduce the problem you mentioned. I added one more test case to
drools source code anyway (see commits for this ticket).
If you are able to reproduce the problem, would you please attach a test case so that I
can see and fix the problem?
Also, please not that even being possible to use "collect" to count the number
of facts, if you only want to count them, the preferred (lighter) way of doing is using
accumulate function count:
Number( intValue == 1 ) from accumulate( SomeFact(), count(1) )

Error in BaseIntFieldClassReader for ArrayList ( size == 1)
-----------------------------------------------------------
Key: JBRULES-1766
URL: https://jira.jboss.org/jira/browse/JBRULES-1766
Project: JBoss Drools
Issue Type: Bug
Security Level: Public(Everyone can see)
Affects Versions: 5.0.0.M2
Environment: Eclipse 3.4; Drools SVN trunk from today, Linux
Reporter: Michael Zimmermann
Assignee: Edson Tirelli
Fix For: 5.0.0.M2
The following rule worked perfectly with drools 4.0.x. Using Drools Trunk (post 5.0 M1) I
do get an error in org.drools.base.extractors.BaseIntClassFiieldReader. Changing the
ArrayList (size==1) definition to ArrayList() works, though.
rule "MyRule"
when
ArrayList( size == 1 ) from collect ( SomeClass( ) )
then
do_something ()
end
As this is some hack also published on the mailing list for counting facts, I would
expect to see this contruct to be compatible with drools 4.0.x
