Re: [rules-users] Multiple Excel decisiontables - a bug
Thomas Thanks for the reply. It makes sense to specify the rule names explicitly. If I have several hundreds of rows ( several spreadsheets), giving a unique name for each rule is time consuming. I guess I can use some Excel functionality to generate the unique names. Excel is fairly clever so if you have cell whose content ends with a number when you drag the black box to copy the contents into the cells below it will automatically increment the value. If you have just a single rules table then this won't take long at all, I do agree however that if you have lots of rules tables this could get tedious. What do you think about the feature of auto generating the names? Let us say, if the the name of spreadsheet is appended with 11, 12 etc I can have the rule name generated automatically (of course, presuming I give an unique name for each spreadsheet... which is far less effort). Sounds sensible to me, and from what I have seen shouldn't be that hard to change the code to do this. I've got a whole list of features that I'd like to do to improve the spreadsheet support, the project I'm working on is using them and I'm hoping to get some time to work on it but as it is currently running behind I'm not sure if that is going to happen or not. Thomas Swindells, Thomas wrote: My advice is always to include a rulename (NAME) column and explicitly specify all the rule names. That way the name of the rule is deterministic and doesn't suddenly change if someone happens to insert a rule in the row above - this is particularly useful if you log or audit the rules that have fired. Thomas -Original Message- From: rules-users-boun...@lists.jboss.org [mailto:rules-users- boun...@lists.jboss.org] On Behalf Of satjo Sent: 18 November 2009 16:50 To: rules-users@lists.jboss.org Subject: [rules-users] Multiple Excel decisiontables - a bug I think following is a bug and I would like to how different users think Issue: If there are multiple Excel decisiontables files, i.e, NOT multiple decision tables in a single spreadsheet, then the 'fireall' does not necessarily give right results as the rule names get repeated in the resolved drl file. How to produce?: One can produce this issue adding multiple Excel files in Knowledbuilder and also one can see the same problem in Guvnor when one uploads multiple Excel decision tables. Reason for the behavior: The rule name (with row number post fix) gets repeated if all the spreadsheets for the given model. Let us say if I have a model 'com.sample.Test' and two spreadsheet decision tables use this model, then the final resolved drl file would have two rules with the same name, e.g. Test_11 etc. I looked into the code 'org.drools.template.model' and name is not unique between different spreadsheets. If this name is unique, e.g. name of the spreadsheet (presuming each spreadsheet is having unique name), then I do get correct results. I want to know if any one has similar experience or comments. -- View this message in context: http://old.nabble.com/Multiple-Excel- decisiontables---a-bug-tp26408909p26408909.html Sent from the drools - user mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users *** *** This message is confidential and intended only for the addressee.

[rules-users] from clause in decision table.
I've got a fact which contains a collection (a set of strings to be precise). I want to write a rule which fires if there are any invalid values (where the valid values are defined as a list). What I'm trying to do is express this within a decision table. Expressed as a drl rule the following works: rule ValidateList when Fact(col : collection != null) String(this not in ($param)) from col Then #generate error End Where $param = '1, 3, valid' The decision tables seem to assume that the fact type is the last element in the line and then appends ( conditions... ) this means there is no way to then insert a from ... after it. Does anybody know either a different way to structure the rule so that I don't need a from or a way to get the decision table to use it? (unfortunately adding the collection directly as a fact isn't an option). Thanks, Thomas ** This message is confidential and intended only for the addressee.

[rules-users] How do I resume a paused process?
I have a process that pauses after a few nodes are executed because it reaches a Human Task node. I retrieve the persisted session with the following code: JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, null, getEnvironment()); Once I have this session object I'm not sure how to resume the paused process? I want to signal the Human Task work item as complete and have the process resume at that point. I've tried this code: WorkItemManager wm = session.getWorkItemManager(); wm.registerWorkItemHandler(Approve, new WSHumanTaskHandler()); WorkflowProcessInstance pi = (WorkflowProcessInstance) session.startProcess(processName); Object[] nodes = pi.getNodeInstances().toArray(); WorkItem wi = ((HumanTaskNodeInstance) nodes[0]).getWorkItem(); wm.completeWorkItem(wi.getId(), null); session.dispose(); The result of this is that the workflow restarts from the first node and completes to the end. I expected that the workflow would start at the persisted location. What am I missing here?

Re: [rules-users] How do I resume a paused process?
You need to have at least the process instance id or the work item id to get your things done. session.startProcess(processName); This will always starts a new process You have to get hold of your process instance or you can directly complete the work item if you have the work item id. StatefulKnowledgeSession ksession = JPAKnowledgeService.loadStatefulKnowledgeSession(sessionId, kbase, null, getEnvironment()); WorkflowProcessInstance inst = (WorkflowProcessInstance)ksession.getProcessInstance(process instance id); get hold of the work item and complete it OR If you have the work item id already you can do this directly ksession.getWorkItemManager().completeWorkItem(workitemid, null); -Original Message- From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of Scott Stevenson Sent: Thursday, November 19, 2009 11:00 AM To: Rules Users List Subject: [rules-users] How do I resume a paused process?

[rules-users] drools flow package issue
Drools version: 5.0.1
I defined two flows, one is main flow and the other is sub flow.
These two flows have same package name, and are built and added into one
knowledge base.
When I start the main flow process, the NoSuchMethod error is thrown out.
I also test with two unrelated flows, and I can't get correct result.
So my question is that whether there is the constraint which two flows must not
have same package name?
