Please help me on hibernate-meet-drools

by Hong Ju

Hi, I would like Drools to save my POJO objects as Hibernate Entities so that I can see my POJO objects as db tables in my database. I tried to make this work by searching on the net, but there is very limited example on this topic, my code does not have any error, but it does not save any tables in my db. I attached my project in this email, if someone can help me on this, this will be so great and make me move forward. Thank you so much in advance, Hong Lily Ju Software Engineer hong.ju(a)steward.org<mailto:derrick.smith@steward.org> Steward Heath Care [Description: cid:image001.png@01CD0DC1.C0D81BD0] Office: 781-375-3034 Cell: 781-801-9313

No errors thrown from KnowledgeAgent

by De Rooms Brecht

Dear Drools users, I have been testing with the KnowledgeAgent from version 5.4 and 5.5. It monitors a changeset and is set to incrementally build the knowledgebase. I noticed that it sometimes crashes but never throws out errors. This happens for example when I define a type two times and when I remove a file. Does anyone experience similar behaviour and has an idea of how I could see the errors? I already tried to check the errors by building it myself using a knowledgebuilder before I update the file that the knowledgeAgent monitors but that's quite a dirty solution. Kind Regards, De Rooms Brecht

Dependency enumeration

by agarwalk

Hi I have created following enumeration and java class file. *Enumeration:* 'OrderData.propertyState':(new com.asps.rules.OrderData()).loadStates() 'OrderData.fulfillmentReviewerName[propertyState]':'(new com.asps.rules.OrderData()).loadReviewers("@{propertyState}")' *Java class:* public class OrderData implements Serializable { private String propertyState; private String fulfillmentReviewerName; // getters and setters public List<String> loadStates() { List<String> states = new ArrayList<String>(); states.add("CA"); states.add("NY"); states.add("FL"); return states; } public List<String> loadReviewers(final String propertyState) { List<String> reviewers = new ArrayList<String>(); System.out.println("### in load reviewers ### : " + propertyState); if ("CA".equalsIgnoreCase(propertyState)) { reviewers.add("A"); reviewers.add("B"); System.out.println("Reviewers : A & B"); } else if ("NY".equalsIgnoreCase(propertyState)) { reviewers.add("C"); reviewers.add("D"); System.out.println("Reviewers : C& D"); } else if ("FL".equalsIgnoreCase(propertyState)) { reviewers.add("E"); reviewers.add("F"); System.out.println("Reviewers : E& F"); } else { reviewers.add("G"); reviewers.add("H"); System.out.println("Reviewers : G& H"); } return reviewers; } } I created a rule as follows WHEN There is an OrderData with: propertyState[propertyState]* FL* --- This is a drop down which is being displayed correctly fulfillmentReviewerName [fulfillmentReviewerName] -- This should have been the drop down. Values are dependent on the state selected. When i try to create above rule the enumeration is loaded correctly for propertyState but the enumeration is not loaded for fulfillmentReviewerName field. When I saw the logs the correct method and condition is being invoked (as per Sys out)but drop down does not contain anything.

Guvnor 5.5.0.Final Web decision table's advanced enum is not working.

by Soumya.plavaga

Hi, We are trying to use the advanced enumeration with guvnor 5.5.0.Final. But seems not working for us. We are doing this - Having model cascadedModel. CascadedModel has following fields - 1. categoryField (Type Text) 2. departmentField. (Type Text) Cascaded model has a fact called - cascadedFact. Created an enum called cascadedEnum having following - Fact => 'cascadedFact' Field => 'categoryField' Context => '(new com.ugamsolutions.projectname.guvnorhelper.CategoryListing()).getAttributeListByName("categoryName")' Fact => 'cascadedFact' Field => departmentField[categoryField] Context => '(new com.ugamsolutions.projectname.guvnorhelper.DepartmentListing()).getAttributeListByNameAndCategoryIdString("departmentName","@{categoryField}")' And using these two enums in a web decision table's drop down. First drop down suppose to display all the categories returned for 'categoryField' and second dropdown will return the departments based upon category dropdown selection. Here my case Category drop down is listing properly, no issues. But upon category selection department dropdown is not loading at all. Actually I can see '{@categoryField} in enum is not replacing the primary drop down's selected value. Can you please take a look and let me know if there is any issue with the advanced dropdown with web decision table in guvnor 5.5.0.Final war? Any help will be really appriciated.

classloader problem in Drools 6.0.0.CR1 and CR2 (working in Beta5)

by Martin Minka

Attached is Grails application which uses Drools. It works with Drools 6.0.0.Beta5, but stops with CR1. You need Grails on your PC to run the application. Easiest is to use http://gvmtool.net/ to install Grails 2.2.4. * unpack grails-drools6.tar.gz * cd to this folder * run: grails run-app * visit http://localhost:8080/grails-drools6/drools/index * this time you will see "ok" in browser, because it will use 6.0.0.Beta5 * stop grails by pressing Ctrl+C now to reproduce the problem: * comment out line 2 in grails-drools6/grails-app/conf/BuildConfig.groovy * run: grails run-app * visit http://localhost:8080/grails-drools6/drools/index * this will fail with message related to compiling of "global com.xtmotion.builder.DroolsFactBuilder kb;" in xtrules.drl
