Michael Zimmermann commented on JBRULES-1766:
---------------------------------------------
Yes (Trunk Plugin) and Yes (Eclipse 3.4). Both from the maven build generated a couple
days ago.
Well, even running the plugin from within my eclipse via "Debug Plugin" I do
get the error yet no stacktrace or whatever. The only thing I see is this:
Description: org/drools/base/extractors/BaseIntClassFieldReader
Resource: PipeConnections.drl
Path: Kns-Drools/src/rules Unknown
Location: Unknown
Type: Drools Error
One of the relevant lines is:
ArrayList( size == 2 ) from collect( GenericPipePortKequipment( ) )
GenericPipePortKequipment is proxy class that hooks into our OWL ontology.
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
