Unable to share model between different packages in Guvnor 5.0.0

by devan.vanreenen＠gmail.com

Hi there, Please assist. I promote 2 POJO model jars and a declarative model to the global area in Guvnor. I then create a upload a new POJO model jar and declarative model but select not to "create new" but to import the models from global area, however there is nothing in the drop down of available assets to import from global area. Please confirm what I might be doing wrong. Thanks Devan -- View this message in context: http://drools.46999.n3.nabble.com/Unable-to-share-model-between-different...

Re: [rules-users] Different Thread Handling between fireAllRules() and fireUntilHalt()

by totempole

The issue occurs only when fireUntilHalt() is launched in Drools-Spring integration, like this, <drools:ksession id="ksession" type="stateful" name="ksession" kbase="kbase" > <drools:batch> <drools:set-global identifier="droolsServiceUtil" ref="droolsServiceUtil" /> *<drools:fire-until-halt />* </drools:batch> </drools:ksession> When I invoke the same method in Java below, the issue doesn't show up. Could it be a bug in Drools-Spring integration? @Async public void fireRulesUtilHalt() { try { getKsession().fireUntilHalt(); } catch ( ConsequenceException e ) { throw e; } } -- View this message in context: http://drools.46999.n3.nabble.com/Different-Thread-Handling-between-fireA...

How to get list of rules that we modified/added/deleted

by aomkaram

When I add/update/delete the rules in decision table and when I press "save changes" I should get the list of rules I recently added/updated/deleted for doing some validation before I save it. Is there any callback/api to get the rules only that I have modified from last save?

Formula error in Business Rule(Guided editor)

by Manasi

Hi, Currently I am facing following issue while inserting a formula in Business Rule(Guided Editor): 1) I have written following formula to be executed in Business Rule(Guided Editor): WHEN 1. The following exists: There is a RuleObject [$r] with: installations < 100 THEN 1. Insert RuleObject: calulatedValue = $r.installations*3 But it gives error 'Unable to analyse expression' when i try to Verify the rule. I want my end result will be a calculated value instead of Literal value. Please let me know the correct syntax to use formula in this type of rule. Thnaks. -- View this message in context: http://drools.46999.n3.nabble.com/Formula-error-in-Business-Rule-Guided-e... Sent from the Drools: User forum mailing list archive at Nabble.com.

Using "collect" repeatedly over sub-groups of a fact

by Mike Goldner

I have a single rule that includes a "collect" pattern to pass a collection to the RHS. However, what I now need to do fire this rule for multiple collections based on groupings defined by attributes on the fact. Here is an example: Fact(a = 1, b = 1, c = 1) Fact(a = 1, b = 1, c = 2) Fact(a = 2, b = 1, c = 3) Fact(a = 2, b = 2, c = 4) Fact(a = 2, b = 2, c = 5) I would like to create sub-groups based on the attributes 'a' and 'b'. My rule should fire three times for the facts listed above, providing the corresponding collection of Fact. The only solution that I can think of is to build a HashSet and add each Fact to the HashSet using the attributes as keys. I suppose it would have to be a nested set since I can't define a multi-valued key class within a rule. I could then handle this HashSet in a RHS block. However, I realize that I'm completely subverting the whole rule language Any suggestions? Thanks, Mike
