Nevertheless, I can edit the file, the RCP runs with the new rules, etc.<div><br class="webkit-block-placeholder"></div><div>In my plugins, I have the main eclipse drools feature and plugin; in my workspace I have the core drools project that contains the compiler, core, and limited dependencies. I have also exported the latter plugin, and dragged it into my eclipse installation.</div><div><br class="webkit-block-placeholder"></div><div>Do these three different things foul each other up?
