incorrect eval() results when accessing global ---------------------------------------------- Key: JBRULES-2898 URL: https://issues.jboss.org/browse/JBRULES-2898 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-core Affects Versions: 5.1.1.FINAL Reporter: Wolfgang Laun Assignee: Mark Proctor Fix For: 5.2.0.M1 Combinations of rules containing an eval CE comparing double > double or double > integer may cause the eval result to be in error. In the attached example, there are 4 rules. If all are used, 2 fire when they should not. If rules 1+2 or 3+4 are used, 1 fires when it should not. If rules 1+4 or 2+3 are used, none misfires. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira

KnowledgeAgentDefinitionParser can get NPEs ------------------------------------------- Key: JBRULES-2930 URL: https://issues.jboss.org/browse/JBRULES-2930 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-spring Affects Versions: 5.1.1.FINAL Reporter: stevearoonie Assignee: Mark Proctor KnowledgeAgentDefinitionParser assumes that a spring bean definition has a bean class name, however when the bean extends a parent then it may not, as in the following example: <bean id="messageTemplateService" class="au.com.promedicus.template.freemarker.FreemarkerTemplateService"> <constructor-arg ref="workflowFreemarkerConfiguration"/> </bean> <bean id="workflowFreemarkerConfiguration" parent="freemarkerConfiguration"> <property name="templateLoader"> <bean class="au.com.promedicus.core.messaging.freemarker.FreemarkerMessageLayoutTemplateLoader" /> </property> </bean> The BeanDefinition for bean "workflowFreemarkerConfiguration" has a null bean class name which causes KnowledgeAgentDefinitionParser.parseInternal to throw an NPE.

Basically the execution-server isn't polling Guvnor-server for changes to rule resources...only way to trigger a refresh is to touch the deployment descriptor - which is a dirty hack && takes the service down for a few moments. It would be fantastic to get this implemented in the otherwise excellent execution server 5.2 TIA!! -- This message is automatically generated by JIRA.
