[rules-users] Drools bpmn gateway constraints questions

[mattmadhavan]

Hello,
I am trying create a few constraints (XOR).  I have a .DRL file with 3
agenda-group. I am also using a custom evaluator and few global static
functions.

Mine is a Stateless Session with bunch of records (Caner records)

1. How do I refer to the current fact? 
- Can I do something like this?
*$cancerRecord : CancerRecord ()*

2. How do I invoke external functions?
Can I do something like

*inlist* ($cancerRecord.PRIMARY_SITE,  "C500, C501, C502, C503, C504, C505,
C506, C508, C509")
*containsAny* (kcontext, $cancerRecord,
"505101,505102,505103,505104,505105,505106,505107,505108")


*not inlist *($cancerRecord.PRIMARY_SITE,  "C500, C501, C502, C503, C504,
C505, C506, C508, C509")
*not containsAny *(kcontext, $cancerRecord,
"505101,505102,505103,505104,505105,505106,505107,505108")

*Please note that inlist and containsAny are valid functions that work. But
I am not able to import tham within the constrains.*

I not able to locate any documentation in this. Can some one point me to the
right documentation. I have been stuck on this for couple of days.

Any help is appreciated.

Thanks in advance!
Matt'm
