To view the discussion, visit: https://community.jboss.org/message/783821#783821 -------------------------------------------------------------- Hi! By using Fluent API I want to create a Business Process as Shown below:- https://community.jboss.org/servlet/JiveServlet/showImage/2-783821-20012/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-783821-20... Now I'm using the following code given below to create such a kind of process:- public class ProcessFactoryTest {             public void testProcessFactory() {                       RuleFlowProcessFactory factory = RuleFlowProcessFactory.createProcess("org.jbpm.process");                     factory                                                              .name("My process").packageName("org.jbpm").imports("com.test.SendHTMLEmail","com.test.Name").variable("listName", new ListDataType())                                                              .startNode(1).name("Start").done().joinNode(2).type(org.jbpm.workflow.core.node.Join.TYPE_XOR).done().connection( 1,2).humanTaskNode(3).actorId("shahid").done().connection(2, 3)                                 .splitNode(4).type(Split.TYPE_XOR).constraint(2, "Join node", "code", "java", "return (false;").constraint(5, "Usertask Node", "code", "java", "return (true;").done().connection(3, 4).endNode(5).name("End").done()                                                              .connection(4, 5);                                                                                              RuleFlowProcess process = factory.validate().getProcess();                                                       }           public static void main(String args[])           {                     new ProcessFactoryTest().testProcessFactory();           } }   While executing the above specified code I'm having the following error (When I use fluent API) :- "Process 'My process' [org.jbpm.process]: Join node 'null' [2] does not have more than one incoming connection: 1.           Process 'My process' [org.jbpm.process]: Split node 'null' [4] does not have more than one outgoing connection: 1.           Exception in thread "main" java.lang.RuntimeException: Process could not be validated !           at org.jbpm.ruleflow.core.RuleFlowProcessFactory.validate(RuleFlowProcessFactory.java:125)           at com.sample.ProcessFactoryTest.testProcessFactory(ProcessFactoryTest.java:43)           at com.sample.ProcessFactoryTest.main(ProcessFactoryTest.java:59)"   -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/783821#783821] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
