Question about custom accumulation functions

by Bruno Freudensprung

Hi, While testing my custom accumulation function I noticed an unexpected behavior (th'ats of course a personal point of view). It seems that Drools 5.1 calls accumulate(...) and getResult(...) as many times as the number of accumulated facts (accumulate, getResult, accumulate, getResult, etc...). Is it supposed to work like this? Best regards, Bruno.

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 - Loading enums programatically using rule metadata

by GPatel＠tsys.com

The Guvnor manual specifies how to load enum data programtically but it seems like only other fields on the same Fact can be used to filter the values that can show up in the drop-down fields, as shown below: 'Fact.field[dependentField1, dependentField2]' : '(new com.yourco.DataHelper()).getListOfAges("@{dependentField1}", "@{dependentField2}")' Is it possible to somehow use other rule attributes, like package name or rule metadata to filter the list? Something like the following: 'Fact.field[dependentField1]' : '(new com.yourco.DataHelper()).getListOfAges("@{dependentField1}", drools.getRule().getMetaData().get("ID"))' Thanks G.

Guvnor in Reselliency environment : Assets stored in DB not visible in Secondary server

by Zahid Ahmed

I am working in Drools-Guvnor-5.5.0.Final version and have configured repository.xml to save all assets + indexes in Oracle 11 database. I am deploying Guvnor in a resilient environment which has two servers. Guvnor deployed in both the servers is pointing to the same database. Step 1 For this I generated the repository.xml from the administration panel of Guvnor and replaced in both primary and secondary Guvnor instance. And when I started the server and imported assets into primary guvnor, I was able to see the following tables in database, 1. FS_FSENTRY; 2. FS_WS_DEFAULT_FSENTRY; 3. PM_WS_DEFAULT_FSENTRY; 4. PM_WS_DEFAULT_BINVAL; 5. PM_WS_DEFAULT_BUNDLE; 6. PM_WS_DEFAULT_REFS; 7. PM_WS_DEFAULT_NAMES; 8. REPOSITORY_FS_FSENTRY; 9. VERSIONING_FS_FSENTRY; 10. VERSIONING_PM_BINVAL; 11. VERSIONING_PM_BUNDLE; 12. VERSIONING_PM_NAMES; 13. VERSIONING_PM_REFS; I also configured workspace.xml files in 1. jboss-eap-6.0/bin/repository/workspaces/default 2. jboss-eap-6.0/bin/repository/workspaces/security Step 2 Now started secondary guvnor, configured similar to primary Guvnor. But secondary server did not displayed the packages and assets from DB. Instead asked me to install sample packages. Step 3 I configured DataStore in repository.xml. Restarted primary Guvnor server and found one more table is created in database with the assets init. Table name : DS_DATASTORE Step 4 Configured secondary Guvnor with DataStore and restarted it. Now I could see the packages of primary Guvnor, But the assets in packages were not available. I am attaching the repository.xml file from both the servers.
