Re: Inserting Facts within "Action nodes" (RuleFlow)
by Massi Gmail
Thank you very much Kris.
I will define such a rule.
thanks again.
Now I am experiencing something different...
I would like to introduce if\while statements into the action node
"code part".
Is that possible?
Every time i introduce such a statement into
the "textual editor "I get back a Mvel exception.
In case It were not possible, I think I would use
another rule like the one you suggested me.
Grazie.
Massi

The ruleflow action node can be used to specify some action (as a piece of code) that should be executed. Currently, it only has access to global variables. It might indeed be a good idea to also allow access to some kind of workingMemory variable. We will try to add support for that when we add support for process variables. If you want, you could open a JIRA for this to track the issue.
Your solution, defining wm as a global, seems a possible workaround (and I don't see any problems that might arise by doing this). Another one would be using a ruleset node instead of an actionNode, and specifying a rule that does not have any conditions, something like:
rule "MyRule"
ruleflow-group "MyAction"
when
then
insert(new Object());
end

Hi guys,
Is it possible to insert a new fact in the ruleflow action nodes?
I tried it simply adding an "insert(new Object())" instruction
in the action-node "textual editor" but I got back the following
exception:
org.mvel.PropertyAccessException
: unable to resolve property: insert(new Object())
Is it a simple dialect issue ? How to do it correctly?
Thank You!

Custom EvaluatorFactory
by Andy Mei
Hi,
Is there a way I could register my own custom EvaluatorFactory?
Drools ships with DateFactory what compares only dates, but no time is
included. I would like to compare time as well.
I see that it would be very helpful to include capability to register
custom EvaluatorFactory.
Thanks.

Re: JUnit and classpath
by J Michael Dean
I noticed the absence of asm and tried to manually add version 3.1 and
this had no effect on the trace.
The MinimalDrools plugin is just my plugin to contain what I thought
was the minimal amount of Drools stuff; I have the exact same error
when I put everything that is in the Drools distribution in the
classpath.

Inserting Facts within "Action nodes" (RuleFlow)
by mmquelo massi
Hi guys,
Is it possible to insert a new fact in the ruleflow action nodes?
I tried it simply adding an "insert(new Object())" instruction
in the action-node "textual editor" but I got back the following
exception:
*
org.mvel.PropertyAccessException*: unable to resolve property: insert(new
Object())
Is it a simple dialect issue ? How to do it correctly?
Thank You!

Re: Inserting Facts within "Action nodes" (RuleFlow)
by Massi Gmail
I think i worked it around.
Before I fired the rules, I put the following instruction in the "main" code:
workingMemory.setGlobal("wm", workingMemory);
Ofcourse in this way I can access the working memory within
the ruleflow action nodes and I can use them in order
to assert new facts into the "wm" global.
Does it sound a bit tricky?
Does it imply horrible integrity\security issues?
Please, I need a feed back from the "drools" guys to know whether
what I did is correct or not.
Thank You everyone.

Qualifing objects on LHS
by kissro＠lidp.com
Hello,
I have the following rules with the corresponding code in the LHS of
each in a single .drl file. These were not written by me but by someone
just as new to drools as I am. At the moment I'm not concerned with the
RHS of the rule.
rule "L_Quest_Q1_Add"
salience 20
when
not FormResponse(questionNumber == "Q1")
l_Quest : L_Quest(questionNumber =="Q1")
rule "L_Quest_Q3_Add"
salience 20
when
not FormResponse(questionNumber == "Q3")
l_Quest : L_Quest(questionNumber =="Q3")
rule "L_Quest_Q2_Add"
salience 10
when
formResponse1 : FormResponse(questionNumber == "Q1",
responseData == "Yes")
not FormResponse(questionNumber == "Q2")
l_Quest : L_Quest(questionNumber =="Q2")
rule "L_Quest_Q4_Add"
salience 10
when
formResponse3 : FormResponse(questionNumber == "Q3",
responseData == "Yes")
not formResponse4 : FormResponse(questionNumber == "Q4")
l_Quest : L_Quest(questionNumber =="Q4")
I want to rewrite these rules in a .dsl file making them as generic as
possible. Something like
when question {q} is not answered=not FormResponse(questionNumber == {q}
My question is regarding how to reference the 'formResponse' object.
For rule Q2_Add, do I really need to create 'formResponse1' and for rule
Q4_Add, do I have to create 'formResponse3' and 'formResponse4'? I
don't really want to have specific rules in my .dsl file like
when question 1 is answered=FormResponse1(questionNumber == 1, etc.
when question 3 is answered=FormResponse3(questionNumber == 3, etc.
when question 4 is not answered=not FormResponse4(questionNumber == 4)
Since I may have lots of questions, I don't want to have to have the
numbers hard-coded in the .dsl syntax if I don't have to. That's why
I'm wanting to know if I have to qualify 'FormResponse' so the rule
engine knows which 'FormResponse' I mean.
Thanks,
Rod

Re: JUnit and classpath

Thanks. When I do that, there is no reference to org.objectweb.asm,
nor is there even any reference to any asm library. The information is
about 800 lines long and it clearly shows classes loading from my
"minimal core Drools" plugin; when I add the entire Drools
distribution to the classpath I get a similar dump with loading from
the complete Drools distribution. I am attaching a text file with
this information but I am guessing it will get stripped away by the
server. I very much appreciate your help with this.
