Hi, I just downloaded the Drools 5.1.0.M2 (have been using the snapshot version of around 16th April 2010) - created a sample "rule flow file(start-->user task-->end) - bpmn2 version". But when I clicked the file to open it gave the following error (image attached) "The method getTextContent() is undefined for the type Node" . I understand this error is related to org.w3c.dom.Node where this method was added as part of DOM Level 3 and available in JDK 5+ . My project and eclipse is configured against JDK 6+ . Not sure why this error with M2. May be it is because of the drools-bpmn2.jar included in the drools eclipse plugin? Can someone shed some light that where it might be going wrong.
