[JBoss JIRA] Created: (JBRULES-2781) Optimization for sub-attributes in LHS conditions

by Frederico Ramos (JIRA)

Optimization for sub-attributes in LHS conditions ------------------------------------------------- Key: JBRULES-2781 URL: https://jira.jboss.org/browse/JBRULES-2781 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-compiler, drools-core Affects Versions: 5.1.0.FINAL Environment: Windows XP & 7 Pro, Eclipse Galileo, JDK 1.6 update 21 Reporter: Frederico Ramos Assignee: Mark Proctor Priority: Minor When building a simple rule, we discovered that the resulting "rete tree" did not reused some node conditions, dispite they are listed in the same order. After some different approaches we get to the expected tree using explicit predicates. Shouldn't both alternatives generate the same tree? And if don't, can some optimization be created in Drools CORE to handle this? Note that although the tree is different, it uses the same node types.
