----------------------------------------

This is really strange. I will setup an environment here and let you know.

> 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
