Drools server and knowledge agent functionality
by Manuel Ortiz
Hello everybody:
I am taking a look at Drools Integration documentation to understand how
Drools server works and how can be used, and have a doubt concerning, let's
say... 'KnowledgeAgent capabilities'. Does Drools server support on the fly
rule updating as when using KnowledgeAgent to create KnowledgeBase objects?
If it does, where can be configured 'KnowledgeAgent related' properties such
as newInstance or resource scanner interval?
Thank you in advance for your time.
Kind regards,
Manuel Ortiz.

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.

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,

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.
ANy suggestions?

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.
Many Thanks,
Soumya
