Franck cdsosi [https://community.jboss.org/people/cdsosi] created the discussion "Timer Boundary Event on ScriptTask ClassCastException raised at KnowledgeBase creation" To view the discussion, visit: https://community.jboss.org/message/755827#755827 -------------------------------------------------------------- Hi, Some problems seems to occur when you set a Timer Boundary Event on a Script Task. When you try to create under eclipse a Knowledge Base with this kind of sample process (see attached file) you get the following exception : java.lang.ClassCastException: org.jbpm.workflow.core.node.ActionNode cannot be cast to org.jbpm.workflow.core.node.StateBasedNode     at org.jbpm.bpmn2.xml.ProcessHandler.linkBoundaryEvents(ProcessHandler.java:437)     at org.jbpm.bpmn2.xml.ProcessHandler.end(ProcessHandler.java:144)     at org.drools.xml.ExtensibleXmlParser.endElement(ExtensibleXmlParser.java:417)     at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.endElement(AbstractSAXParser.java:601)     at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaValidator.endElement(XMLSchemaValidator.java:828)     at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanEndElement(XMLDocumentFragmentScannerImpl.java:1782)     at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl$FragmentContentDriver.next(XMLDocumentFragmentScannerImpl.java:2939)     at com.sun.org.apache.xerces.internal.impl.XMLDocumentScannerImpl.next(XMLDocumentScannerImpl.java:647)     at com.sun.org.apache.xerces.internal.impl.XMLNSDocumentScannerImpl.next(XMLNSDocumentScannerImpl.java:140)     at com.sun.org.apache.xerces.internal.impl.XMLDocumentFragmentScannerImpl.scanDocument(XMLDocumentFragmentScannerImpl.java:511)     at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:808)     at com.sun.org.apache.xerces.internal.parsers.XML11Configuration.parse(XML11Configuration.java:737)     at com.sun.org.apache.xerces.internal.parsers.XMLParser.parse(XMLParser.java:119)     at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(AbstractSAXParser.java:1205)     at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(SAXParserImpl.java:522)     at javax.xml.parsers.SAXParser.parse(SAXParser.java:395)     at org.drools.xml.ExtensibleXmlParser.read(ExtensibleXmlParser.java:296)     at org.drools.xml.ExtensibleXmlParser.read(ExtensibleXmlParser.java:175)     at org.jbpm.compiler.xml.XmlProcessReader.read(XmlProcessReader.java:46)     at org.jbpm.compiler.ProcessBuilderImpl.addProcessFromXml(ProcessBuilderImpl.java:247)     at org.drools.compiler.PackageBuilder.addProcessFromXml(PackageBuilder.java:652)     at org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:688)     at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:45)     at org.drools.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:34) ...
