DSL parsing List of Strings
by Trägenap
Hi,
how I can define a list in a DSL-file?
So user should define a list of comma separated reations (Strings)in a
DSL-rule-file, like this {"r1","r2","r3"}
This list should be used as parameter for "in"-command.
I always get:
mismatched input '{' expecting ')
no viable alternative at input '{' in rule
DSLR:
when
Reaction appears {"r1","r2","r3"}
DSL:
[condition][]Reaction appears {reactions}=
$interactionrequest : Interactionrequest($state in ({reactions}))
Thanks for advice

Drools Flows on web systems?
by Cristiano Gavião
Hi drools people,
I came from a long desktop-swing development history, and I always
used statefull connections for everything :-). Now, I have to
adventure myself on a web app and I'm learning drools, seam or grails
for that.
With swing examples I could understand well how to use drools... I
got some tests working well.... But now Im getting some difficult to
understand some concepts with web development. But I'll get there some
day :)
I would like to hear from you people about some things on drools that
I couldn't figure out yet.
Suppose that I have a long process with sub-process and lots of
activities. some of this activities should run automatically by the
system and some activated by human hands (by some forms to fill, some
decision to take, etc). A really workflow.... And I want to track
every step on this process and who is the people doing the human
tasks.... This is a job for Drools Flows, right?
What should be the best approach to take for using drools flows on
this kind of system??? Should I use Drools Server or Guvnor or both
for that job?
And about drools sessions, should I always use Stateless sessions with
those servers?
How could I persist the long process flow instances on a web system?
And about processes scopes, for example, one global variable
declarared in a dsl, used by some rule that is running on different
process instances, they share same value?
Can I have a kind of callback like the on PetStore example that came
with stateless sessions?
Thanks in advance for any help or suggestions

Guvnor deployment exception
by Raphael Duarte Paiva
Hi!
I'm using JBoss 4.2.3.GA <http://4.2.3.ga/> via JBoss Tools and when I try
to deploy drools-guvnor.war I get the attached stack trace.
This one draws my attention as it's the stack's base:
Caused by: java.io.FileNotFoundException: repository.xml (Permission denied)
at java.io.FileOutputStream.open(Native Method)
at java.io.FileOutputStream.<init>(FileOutputStream.java:179)
at java.io.FileOutputStream.<init>(FileOutputStream.java:131)
at
org.apache.jackrabbit.core.TransientRepository$2.getRepository(TransientRepository.java:218)
Where does it try to create the repository.xml file? Is there any way to
modify the path of this file so It would be in a folder with r/w permission
to the user?
Please forgive any grammatical/English errors!
Thanks in advance!

Guvnor Issues
by Herman Post
Hi,
I've been working with the Model feature in Guvnor 5.M4 and have some questions:
1. Is there a way to delete a fact type once created?
2. When I declare a field as a Date it gets included as a java.lang.Date and
the fact will not validate.
3. If I have created two facts, the one created first cannot reference the
second one as the type of a field. The second on can reference the first. It
would be nice to support this forward -referencing feature.
I'd be happy to enter any of these in Jira if they are not already present
(couldn't find them).
Thanks,
Herm
