DSL expander can't add a field constraint to a fact when a previous field constraint has parentheses
----------------------------------------------------------------------------------------------------

                 Key: JBRULES-1632
                 URL: http://jira.jboss.com/jira/browse/JBRULES-1632
             Project: JBoss Drools
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Drl Parser/Builder
    Affects Versions: 4.0.7
            Reporter: Pierre De Swert
         Assigned To: Mark Proctor


I have made a little example to reproduce the problem.

Let us assume we have a very simple Wine class...
public class Wine {
	private int age;
	private String type;
	private String country;
	private String vineyard;
	....

I define the following in my DSL:

[condition][]Il existe un vin "{i}"={i} : Wine()
[condition][]- plus vieux que "{y}"=age > {y}
[condition][]- du crû "{c}"=vineyard == "{c}"

In the following rule, I can't add the last field constraint when the age of the prvious one is  
"($y + 10)"

rule "Very Old Wine"
	
	when
		#conditions
		# there is a wine 10 years older than a person
		> Person($y : age)
		Il existe un vin "$v"
			- plus vieux que "($y + 10)"
#			- plus vieux que "$y"			
			- du crû "Nuits-Saint-Georges"
	then 
		#actions
		
End
