Hi, When deploying a drools - spring - camel project on karaf, I get an exception in this class https://gist.github.com/anonymous/6f502d28811baaf620fa Caused by: java.lang.NullPointerException at org.drools.compiler.rule.builder.PackageBuildContext.init(PackageBuildContext.java:101) at org.drools.compiler.rule.builder.RuleBuildContext.<init>(RuleBuildContext.java:78) at org.drools.compiler.compiler.PackageBuilder.addRule(PackageBuilder.java:3119) at org.drools.compiler.compiler.PackageBuilder.compileRules(PackageBuilder.java:1013) at org.drools.compiler.compiler.PackageBuilder.compileAllRules(PackageBuilder.java:918) at org.drools.compiler.compiler.PackageBuilder.addPackage(PackageBuilder.java:909) at org.drools.compiler.compiler.PackageBuilder.addPackageFromDecisionTable(PackageBuilder.java:462) at org.drools.compiler.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:703) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:51) at org.drools.container.spring.beans.KnowledgeBaseBeanFactory.afterPropertiesSet(KnowledgeBaseBeanFactory.java:113) as the map of the DialectRegistry is equal to 0 What could be the reason of that problem ? Is it because I'm still using drools-spring ? Regards, -- Charles Moulliard Apache Committer / Architect @RedHat Twitter : @cmoulliard | Blog : http://cmoulliard.blogspot.com
