Re: [rules-users] Spring 4.0 Drools 6.0.1 Integration issue
I debugged the issue. Hi The problem is that it fails when you have the sessions and modules defined in a jar. The path to the pom.properties in the jar file is: META-INF\maven\com.verisk.sws.csp\cepCSP Also I have the issue with webpshere. This treats jars as wsjar There is no condition in the kie-spring integration code to handle wsjar. So it thinks it is a file system and subsequetly fails.

Re: [rules-users] DSL sentence with multiple variables is defect
The issue is solved with build kie-wb 2014-03-22 from
https://hudson.jboss.org/hudson/view/JBoss%20AS/job/kie-wb-distributions/1248/.
The previous build kie-wb 2014-03-15 had the error.
Thank you very much for fixing, direct or indirect :-).
Kai.
2014-03-14 16:51 GMT+01:00 Kai Jemella kjeme...@gmail.com:
My example was bad, because the dsl starts with the same sentence as the
first one in the mortgages project.
Can you please try to set the credit rating variable to OK in the Guided
Editor,
then save, close and reopen the rule.
Now you should see that OK was replaced by AA.
This happens because the value is not in the enum and the editor uses the
first enum value.
When you change the typ of rating to String, you should see this value in
the rating input field: OK and applicant dates is after 14-Mär-2014
Im using this kie-wb build
https://hudson.jboss.org/hudson/job/kie-wb-distributions/1243/
Isn't this the 6.1.0.Beta1 Version ?
Thanks for helping, Kai.
2014-03-13 17:36 GMT+01:00 Michael Anstis michael.ans...@gmail.com:
I tried with the latest code (6.1.0.Beta1) and it works OK.

applicant dates is after {dos:DATE:default} =

Hi,
i recognized that DSL with multiple variables not working in current
6.1.0-SNAPSHOT master.
First i created a jira issue in the drools project:
https://issues.jboss.org/browse/DROOLS-428
I thought it was ui issue. I had closed the ticket and recreated it in
guvnor project.
https://issues.jboss.org/browse/GUVNOR-2081
Now i figured out, that also without edit and save the GuidedRule in kie
workbench, the issue exists.
Should i now reopen the drools ticket?
Should i create a unit test for the issue?
Thanks, Kai Jemella.

[rules-users] Embedded sub-process in drools rule flow
Hi all, Can anyone please tell me whether it is possible to design nested blocks in rule flow. I know that using sub-process, we can embed different rule tasks, but my rule flow file is getting bulkier by the day and I wanted to know if i can have a few rules in a sub-process, but the rule tasks executed by the sub-process should not be visible in the uppermost layer. DOuble clicking on that should take me inside the sub-process and show the rules executed by it. Also if it is not possible to have such an operation with the build in blocks in drools rule flow, can anyone tell me how i can have a custom made block which has that functionality. I have designed custom blocks having simple properties, but i have no idea how this should be done. Hope to get an answer here.

I am using both. And they work great. But so far I have been updating the guided decision table using the admin role. When I create a user in JBoss with user privileges, it wont allow me to even login to Drools workbench. I know guvnor had a different user management approach. But Drools workbench guide does not have enough info on this. Thanks,Vikas.

[rules-users] User Security with guvnor 5.4 and Tomcat 6.0.36
Hi, I have searched extensively for any answers, but have obviously not been looking in the right places. Tomcat is my app server: it should define the users. This is no problem: since it is a small application we want to define our users in tomcat-users.xml, using the UserDatabaseRealm (in preference to MemoryRealm). JAAS or other options are overkill for us. Now, what should I do on the guvnor side? I understand I should be looking at the WEB-INF/beans.xml config file. I can't find much documentation on the contents of this file in general, and nothing specific that seems to help me. A lot of the advice out there seems JBoss AS specific or precedes the move in 5.4 to beans.xml. But, I understand that tomcat in this setting is not supplying a JAAS context, which seemed to be the most likely option. Do I need to implement a version of org.drools.guvnor.server.security.DemoAuthenticator? Is that our only option? Hasn't someone done this before? What would you do in this situation? Any assistance would be greatly appreciated. Thanks, Pete -- View this message in context: http://drools.46999.n3.nabble.com/User-Security-with-guvnor-5-4-and-Tomcat-6-0-36-tp4028945.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
