Thanks for ur reply<br>
<br>
That works if i put everthing in one rule.<br>
When using extends and trying to access the variable in RHS of sub rule<br>
<br>
error in the editor is<br>
<br>
Builder Error:Internal Error:Unable to find declaration in list while<br>
generating the consequence invoker<br>

Second Call for Submissions to the 2009 Rules Challenge<br>
====================================================================<br>
<br>
<br>
The Rules Challenge is one of the highlights at RuleML-2009. Submissions<br>
are bound to come to the attention of a wide audience, for reasons<br>
outlined below. The goal of the Rules Challenge is to encourage any<br>
work of practical relevance in the field of Rule Based Applications,<br>
spanning the range from research to industry.<br>
<br>
<br>
* What to submit<br>
<br>
Submission topics may come from a wide range of the field, such as<br>
(but not limited to) the following:<br>
<br>
- best practice solutions, e.g., design patterns and architecture models;<br>
- case studies and experience reports describing novel or interesting<br>
solutions and use cases;<br>
- benchmarks and other evaluations of rule-based systems;<br>
- tools for manipulating rules and related data in existing or<br>
emerging standards (e.g., RuleML, RIF, SBVR, PRR,...) or commercial<br>
rule-based system implementations;<br>
- engineering methods for development and deployment of rule-based<br>
solutions.<br>
<br>
Authors are invited to submit original contributions of practical<br>
relevance and technical rigor in the field.<br>
<br>
A submission should consist of a paper (typically of 4-8 pages) describing<br>
any theoretical foundation, implementation issues, technical details and<br>
collected results of your work. If applicable, a demonstration program<br>
illustrating your development would be highly valued.<br>
<br>
<br>
* Publication and Review<br>
<br>
Peer-reviewed papers, which must be in English, will be published<br>
in additional special Challenge proceedings, to be published (as<br>
CEUR proceedings </font></tt><a href="www.CEUR-WS.org"><tt><font size=2>www.CEUR-WS.org</font></tt></a><tt><font size=2>),
along with the online publication<br>
of your demo in the highly visible growing Rules Challenge pool<br>
(</font></tt><a href="http://ruleml-challenge.cs.nccu.edu.tw/"><tt><font size=2>http://ruleml-challenge.cs.nccu.edu.tw</font></tt></a><tt><font size=2>).
To ensure high quality,<br>
submitted papers will be carefully peer-reviewed by 3 PC members<br>
based on originality, significance, technical soundness, and clarity<br>
of exposition. A selection of revised papers from the Challenge will<br>
be resubmitted to a special issue of a journal.<br>

Hi Users,<br>
<br>
I am having a doubt regarding the Drools Workflow in my scenario.<br>
I want to integrate Drools Flow in my application and have some doubts
<br>
regarding the <br>
persistence of Workflow process instances.<br>
<br>
Let suppose I have a workflow running in my application and at point <br>
my application crashed or i restart my application. So is their way i can<br>
restart the workflow the point it was.<br>
<br>
If i store the process instance Id in the database, so am I able to start
<br>
my workflow process <br>
from where it had stopped , if it is possible can you tell me the method
<br>
responsible for the same.<br>
<br>
<br>
Please help me to get through the situation.<br>
<br>
<br>
Thanks & Regards<br>

Andre,<br>
<br>
The misunderstanding here is that the LHS, except for code blocks
like<br>
"eval", "return value expressions" and "accumulate
code blocks", are all<br>
"Drools Language". When you use the "dialect" attribute
in a rule or package<br>
you are telling the compiler what dialect (MVEL or Java) you will use inside<br>
these code blocks mentioned previously + the language for the RHS.<br>
<br>
In other words:<br>
<br>
Map( this["type"] == "Point", $x : this["x"],
size == 5 )<br>
<br>
Everything you see in the previous expression is "Drools
language", does<br>
not matter if you set the dialect to java or mvel in the rule. It happens<br>
that Drools uses the same map syntax as MVEL (and a lot of other scripting<br>
languages). Also, we know, that drools implementation will resolve the
first<br>
2 above expressions in MVEL behind the scenes, and the 3rd will be resolved<br>
nativelly, but that is not something users should have to worry about,
since<br>
they are writing it in "Drools Language".<br>
<br>
If they write an eval, THEN they need to differentiate between
MVEL and<br>
Java according to the chosen dialect.<br>
<br>
rule xyz<br>
dialect "mvel"<br>
when<br>
eval( ...here you write MVEL code... )<br>
then<br>
// here you write MVEL code<br>
end<br>
<br>
rule xyz2<br>
dialect "java"<br>
when<br>
eval( ...here you write JAVA code... )<br>
then<br>
// here you write JAVA code<br>
end<br>
<br>
