Re: [rules-users] Is it possible to Iteriate over a list of string values ?

The Expert documentation states "The expression used to define the object source is any expression that follows regular MVEL syntax." Therefore "from" should be able to use the MVEL syntax for arrays ["one", "two", "three"] however I've not tried and never seen it used. Normally people use "from" t

Re: [rules-users] Misunderstanding salience?

Thanks for the ideas, David. What I ultimately want to achieve is to have the individual rules independent of each other to the maximal degree to which that is possible. That's why I didn' t want to have isZombie==false in the general rule - I wanted the general case to be unaware of the ex

[rules-users] Is it possible to Iteriate over a list of string values ?

Hello all, In one of my use cases, I need to insert a variable collections of facts into working memory in order to be able to test for those values later : So I was wondering if there's a way to do something like this when $vals : String() from [ "A 12345", "B 45678", "C 8695" ]

Re: [rules-users] not sure if this is a bug of drools or my bad usage...

Hi Wolfgang, First, your rules work... But for the second rule, I replaced the first Reachable() in the when clause to Link(), and the result is still correct. Only if I remove "no-loop true", the issue I had appeared. So, I understand how "no-loop true" in this case helps to make the result cor

Re: [rules-users] Misunderstanding salience?

Peter, The EXACT way to accomplish the functionality that you are looking for is "activation-group"; if two rules are in the same activation group, only one of them will fire. Note that the rule with HIGHER salience will fire first; to accomplish what you are looking for you'd have to give the

Re: [rules-users] Misunderstanding salience?

Actually, I think I've figured this one out : in the Zombie case, it's firing both rules and it's just that with the negative salience, the zombie exception rule is the last rule fired, therefore, the last thing written into advice. So... what would be the correct way to do what I'm trying t

Re: [rules-users] Process instance status not completing when using JPA.

Thanks for the reply, Kris. I figured it might be something like that, but was thrown because one of the test cases in PersistentStatefulSessionTest (testPersistenceWorkItems3) does check for process state COMPLETE. I worked around the issue by adding a ProcessEventListener that implements the af

Re: [rules-users] Process instance status not completing when using JPA.

Dan, Once you start using persistence, you should know that the process instance you are retrieving is no longer the internal process instance but a version of the process instance at the moment you requested it. This process instance however is disconnected, meaning that it will not automati

Hi There I'm new to drools. I've just set up the Drools-Server and it is (finally!) working and serving my test rule-set. The one thing that's not working as I expect it is the rule ordering via salience. This is my simple test rule set: rule "General brain eating advice" when

Re: [rules-users] Best approach for handling parallel requests for a stateful rules session

They submit the commands to an execution queue, and they're executed in the order received in a thread safe manner. And note there's an asyncFireAllRules() method, so you can time when rules fire. As for whether objects are fed into working memory while rules are firing, I'm not sure, but tha

Re: [rules-users] Best approach for handling parallel requests for a stateful rules session

Took a look... thanks. I'm not sure that they will help me though - do the async methods actually look to see if fireAllRules is already running somewhere else and synchronize the calls? Or do they just wrap a Callable around it so that if your rules take a long time to run you can do something el

I know etiquette stipulates to avoid small talk, but since there is no "resolved" button, I think this can be useful. You suspected rightly, manstis, removing lock-on-active and replacing it with extra constraints in the LHS indeed solved the problem. Thanks for the quick (and correct) response :
