Hallo

I'm looking to integrate the latest Drools version (i have 3.0.4) into a
project, in particular i want to use a DSL. I have a problem using the "Adding
constraints to facts" facility as documented in the user handbook at 3.7.4.

Try the following:

edit org.drools.example.conway.conway.dsl, add

[when]A Cell=Cell()
[when]-is alive=cellState==CellState.LIVE

edit org.drools.example.conway.conway.drl, add

rule "Test"
when A Cell
-is alive
then
end 

in the eclipse IDE / at runtime i get the message "unknown:32:0  Unable to
expand: - is alive. Due to Expression was not expandable: - is alive"

it appears to me someone's inserting a space after the '-'

Any ideas?
