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: Mark Proctor

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
