Drools explicitly disables control statements in MVEL consequences,

Hi Ambika,
your rules in the first rule flow group "MasterHud" set a new value on
a fact's field.
Then you expect that your rules in the second rule flow group fire.
The rule engine has no idea that some facts' fields changed until you
let the engine know via update();
Open your MasterHud deci
Has anybody ported a large number of rules from ILog JRules to Drools?
If yes, I'm very much interested in the following information:
- how did you do the migration (automatic vs. manual)?
- if automatic, how exactly (AST to AST transform, custom JRules
parser, ...)
- which features of JRules

I'm unclear on what you mean by "work with" the stateless session. While it's

Kris,
thanks for the quick reply. It makes perfect sense what you're saying about
the implementation issues on the task level. Did I get it right that e.g. a
specific task for (asynchronous) web service invocation would be implemented
very similar to the WorkItemHandler

Markus,
You should not block the execution thread using long-running tasks (like
sleep()) in actions, as this will actively lock the resources of the
engine. You should use wait states, event nodes and/or work item nodes
if you want to perform long-running tasks. Even when implementing a

Subject: Re: [rules-users] How to execute a Process API result?
Scott,
I'm guessing that you have multiple version of javax.persistence in your
classpath (one in the server war and one on the server classpath),
causing the cast to fail. Could you verify that this might be true?
If so, simply remove the duplicate persistence-api.jar from the server
war, that should f
We might eventually support this in the future, but no plans yet. Reason
is that the static parameters are used for compile time analysis to support
automatic event lifecycle management. Variables would prevent that.

Hi all,

I see you can enter a new DSL, so copy-pasting is an option... but then what

I don't know, we can ask Edson Terelli about that.
If you think about it, its good that the rule condition is always constant.
Because it will describe a static situation in your context.
This, will cause that when you have problems with that rule you will know
exactly what the condition is.

that it knows when to re-evaluate certain constraints. Re-initializing
would mean re-evaluting all rules, and considering you could have a huge
