Thanks.

Drools Flow and jBPM are two separate projects. This is as a result of the need for process integration within the Drools knowledge-oriented platform (and advanced integration between processes and rules), which could not be provided by the jBPM project at that point.

[rules-users] Turning off strict mode
Hello. Is it possible to turn off strict mode in Drools 5.2 or 5.3 like in 5.1? How can i do it? We use Drools 5.1 and we use lots of maps so we turned off strict mode. I tried to switch to Drools 5.2 or 5.3 but setting System.setProperty(drools.dialect.mvel.strict, false) doesn't work with those versions. Our domain model is basicaly a hierarchy of Maps without generics so using strict mode will force us to write alot of casts. This is not acceptable cause we want our non technical guys to write some rules. One of our goals was to make it possible to update our application without recompiling and redeploying any java code only rules and flows, thats why we have such domain model. -- View this message in context: http://drools.46999.n3.nabble.com/Turning-off-strict-mode-tp3468094p3468094.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Time Window
Hello, I want to implement a simple scenario using Drools, but I can't find the right functions to do so. I have a class named Notif that represents my events. When I receive a Notif with a certain attribute (for example, type == A) I want to get a list of all the events I receive in the next 10 seconds. If I receive a second event of type A during those 10 seconds, I don't want to start another count. It should only restart the count after the 10 seconds have expired. Example: 1s: Notif (type==A)should start the 10 second count 2s: Notif (type==B) 3s: Notif (type==C) 4s: Notif (type==A) 5s: Notif (type==D) 12s: Notif(type==E) 10 seconds after the first Notif(type==A) I would like to receive the following list: Notif (type==A) Notif (type==B) Notif (type==C) Notif (type==A) Notif (type==D) Note that Notif(type==E) (at 12 seconds) should not be in the list because it's outside of the 10 seconds interval. Also, note that the second Notif(type==A) (at 4 seconds) should not start a new count because it's included in the 10 seconds interval.

Re: [rules-users] global as link to DB: different results
H... this may be the way it works, but it's not clear from the documentation- The Conditional Element from enables users to specify an arbitrary source for data to be matched by LHS patterns. This allows the engine to reason over data not in the Working Memory. The data source could be a sub-field on a bound variable or the results of a method call. It is a powerful construction that allows out of the box integration with other application components and frameworks. One common example is the integration with data retrieved on-demand from databases using hibernate named queries. I therefore assume ...or the results of a method call should mean ...or the results of a method call on a Fact and the following should work:- rule dao when $cs : CustomerRepository( ) k : Customer( ) from $cs.getCustomerService().findAll() then System.out.println( Drools +drools.getRule().getName()+: +k.getName()); end ? 2011/10/31 Wolfgang Laun wolfgang.l...@gmail.com If the donator isn't a fact, it's not visible to the engine.

Can you bit a little more descriptive? I am having trouble knowing exactly
to what part of Guvnor you refer.

Hi
Is the guvnor custom form not meant for use with fact fields appearing in
dsl sentences? It works fine with guided editor, not with dsl though.
Using 5.3.CR1
Thanks

Re: [rules-users] Guvnor custom form not working for DSL sentences
Is it possible for you to provide a repository export? I think I know what
you have configured but an export would help.

Here's the model:
declare Vehicle
engineType: String
fuelType: String
end
Here's the DSL:
[when]there is a vehicle=$vehicle : Vehicle()
[when]- with engine type {value}=engineType=={value}
[then]say hello=System.out.println(Hello);
When I create a rule using the Guided Editor the usual way (without using
DSL sentences), the custom form does pop up, as shown in attached file
ss1.gif.
When I create a rule using the DSL sentence (when there is a vehicle with
engine type {value}), the value is the usual text field. Clicking on it
does not invoke the custom form. Please see attached file ss-dsl.gif.

[rules-users] Live Queries and Expired Events
I have a live query that should match *all* the events I insert. However, it's apparently not being called for a large number of them. It appears that if an event is expired at the time of insert, it's not tripping the rowRemoved part of the query. Is this the expected behavior? If so, is there some way to catch this condition?

[rules-users] Help with troubleshooting rules/Drools
Any advice on how to troubleshoot problems? I have a fairly simple set of rules (a couple dozen), but keep having problems with fatal exceptions. The most recent was: org.drools.RuntimeDroolsException: Unexpected exception executing action org.drools.reteoo.PropagationQueuingNode$PropagateAction@1e60aa7 at org.drools.common.AbstractWorkingMemory.executeQueuedActions(AbstractWorkingMemory.java:977) at org.drools.common.DefaultAgenda.fireUntilHalt(DefaultAgenda.java:1231) at org.drools.common.AbstractWorkingMemory.fireUntilHalt(AbstractWorkingMemory.java:753) at org.drools.common.AbstractWorkingMemory.fireUntilHalt(AbstractWorkingMemory.java:729) at org.drools.impl.StatefulKnowledgeSessionImpl.fireUntilHalt(StatefulKnowledgeSessionImpl.java:234) at com.kroger.tempmonitor.app.service.RuleService$1.run(RuleService.java:214) at java.lang.Thread.run(Thread.java:662) Caused by: java.util.NoSuchElementException at java.util.LinkedList.remove(LinkedList.java:788) at java.util.LinkedList.removeFirst(LinkedList.java:134) at org.drools.common.PropagationContextImpl.evaluateActionQueue(PropagationContextImpl.java:264) at org.drools.reteoo.PropagationQueuingNode$AssertAction.execute(PropagationQueuingNode.java:357) at org.drools.reteoo.PropagationQueuingNode.propagateActions(PropagationQueuingNode.java:238) at org.drools.reteoo.PropagationQueuingNode$PropagateAction.execute(PropagationQueuingNode.java:502) at org.drools.common.AbstractWorkingMemory.executeQueuedActions(AbstractWorkingMemory.java:975) ... 6 more No mention of a rule name, so where do I begin? My architecture is simple: one thread ran fireUntilHalt(), other (multiple) threads inserting objects. Should I synchronize on the session so only one thread is inserting at a time? There's one rule that triggers a large number of inserts, and it used to give me problems, but I've moved those inserts into Commands and those problems seem to have gone away. Any advice would be welcome, no matter how basic you think it is!

The exception may happen during working memory operations (e.g., an insert), so there isn't even a rule active. Which version of Drools are you using? In my case, switching from Drools 5.2.0.Final to Drools 5.3.0.Final broke 47 of my unit tests (1 error and 46 failures).
