[ https://issues.jboss.org/browse/DROOLS-2279?page=com.atlassian.jira.plugi... ] Matteo Mortari commented on DROOLS-2279: ---------------------------------------- Fixed with https://github.com/kiegroup/drools/commit/7997f8505a391eaa35506361d47e80a... As a result of [DROOLS-2264] the original extension register configuration mechanism is no longer supported. In order to use extension registers, it is now required to configure them using a DMNProfile. Migration guide. Can reference commit [7997f850|https://github.com/kiegroup/drools/commit/7997f8505a391eaa355063...] for an example of migration. 1. Create a DMNProfile with the desired extension registers. Example [create DMNProfile|https://github.com/kiegroup/drools/commit/7997f8505a391eaa3550...] 2. replace old configuration of extension register (system property or kmodule entry) with the configuration of the new DMNProfile created from step1. Examples: [Replace system property|https://github.com/kiegroup/drools/commit/7997f8505a391eaa355063...], [replace kmodule entry|https://github.com/kiegroup/drools/commit/7997f8505a391eaa35506361d...] -- This message was sent by Atlassian JIRA (v7.5.0#75005)
