Hi Jason,
That is not supported at present, but is a work-around (that is consistent
with enum definitions).
Please raise another JIRA and I'll look into that too.
With kind regards,

Eh?
Can you please explain your requirement a bit more.

To be honest it sounds to me as though you need to get one of the Red Hat guys
in to do some proper consultancy for your specific use case.
However...

Then check at the last rule if all the boolean in the rules are true, which

You must not use this:
eval( boolBrandName && boolProviderState && boolDrugStrength )
since changes in global variables are not visible to the Drools rule engine.
But you don't need this eval(...) line, since you have

rule "Provider State" extends "Brand Name"

But one tough question for you.

I want to know what caused the condition a=="b" to fail was the value of a
Sure I'll explain. Assuming I have the following defined in a DSL:
[consequence][]Set result "{name}" to {value} = data.results.put("{name}",
{value});
In the guided BRL rule editor, when I choose to use this DSL to add an
action, the following is displayed
Set rule flag "[name]" to [value]
Hasn't this been answered only recently on this list?
1) For simple conditions, a rule negating the condition of your rule
will fire if the other one fails:
rule "a != b"
when
test( a != "b" )
then
//consequence
end
2) If you have rules extending each other, the first one not firing

It's worth thinking about it differently. A rule does not fail. It just defines
the conditions under which it will activate.
If you wish to perform an action whether the condition is true or false, you
have 2 options:
A positive and a negative condition:
when
test(a == "b")
then

If you're required to determine and log why rules do not fire, you'll
have to do what needs to be done. If you have, for example, 5

I agree with Stephen, if you need an action (e.g. logging) when a constraint

If you do nothing heavy in the RHS, indeed, rules' action part execution is
faster than fact insertion, but this is because of your design, not something

Thanks for reply to all.
I would like to learn how to do that, but I don't want to implement now,
since I do not have time for that. But please do let me know about it.

Yes I have that, but no luck. But again this should be dynamic so I am

Ok it worked when I changed the rule file a little to add the negative rules.

Well, it's a slightly different problem them. Planner's approach
Hi Geoffrey,
Following your advice and after gaining some more understanding of planner,
I think approaching the problem as a chain of tasks one of the other makes
sense. It would have some 'wait' time between tasks where the end time of
the previous task is smaller than the minimum time the task
33 matches
