Hi Mario, For the release notes could you let me know how this issue was resolved. We need to let customers know about any changes in the code that could affect their systems. Thanks Lee
Hi Lee, to fix this issue I just changed the regular expression in the DSL expander to also recognize the case of parametrized queries. This is the commit that fixed that issue: https://github.com/droolsjbpm/drools/commit/ef3892bacd8fbf0742b0a608598b6108d0954db6 Mario
Thanks Mario!
