Re: [rules-users] Guvnor causes NoClassDefFoundError when using functions

Hi, Can you create a JIRA about this? Just in case this is a problem in Guvnor. https://jira.jboss.org/jira/browse/GUVNOR If you can. Give the Guvnor version that you are using and a small repository export or test case that we can use to reproduce this. Thank you Toni Andrew Nguyen wrote:

[rules-users] Simple rule worked in 4.0.7 and failed in 5.0.1

I ran into some problems where a fairly simple rule fails in 5.0.1 and worked in 4.0.7. I have created an issue on JIRA https://jira.jboss.org/jira/browse/JBRULES-2136 and was wondering if someone else has come across that same type of problem. The rule is: package org.drools.rules.test import

I added a comment to the JIRA, but replicate it here for completeness: = Due to some limitations on the way that Drools 4 handles regexps, we had to change the default escaping syntax for regexps, from single escape to double escape. In Drools 5, regexps work exactly like in Java. So,

Chris, The decision between A and B must be taken on the basis of: do you need to join objects from the different streams together? If so, you need A. If not, better go with B. Regarding threads, the engine works with a single thread, unless you activate the KnowledgeBase partitioning

The Expert User Guide, section 2.5.7.3., Agenda Filters, is probably what you are remembering. Also, see the javadoc on org.drools.runtime.rule, interface StatefulRuleSession, method void fireUntilHalt(AgendaFilter agendaFilter) etc. -W On 6/25/09, Chris Richmond crichm...@referentia.com wrote:

Re: [rules-users] firing explicit rules or agend-groups

Sorry for the short answer... busy day. The main problem with agenda filter is that it is defined in application code and so creates a dependency in the rules from the application code. So, you break one of the biggest advantages of rules that is to have a separate lifecycle for rules.

Re: [rules-users] Help debugging NPE

Oh, ok. Then it is shadow proxy related. :) Shadow proxies can't override final methods, and if they can't override them, they can not safely prevent hashcode changes at unsafe points... and that causes all kind of problems with hashmaps that are used internally. Drools 5 no longer
