[jbpm-issues] [JBoss JIRA] Resolved: (JBPM-1778) Empty map variables on process creation is set as null

Empty map variables on process creation is set as null ------------------------------------------------------ Key: JBPM-1778 URL: https://jira.jboss.org/jira/browse/JBPM-1778 Project: JBoss jBPM Issue Type: Bug Security Level: Public(Everyone can see) Components: Core Engine Affects Versions: jBPM 3.2.3 Environment: JBoss 4.2.2.GA, Database HSQL, Ubuntu Linux Reporter: Paco Avila Assignee: Thomas Diesler Fix For: jBPM 3.3.1 GA If I create a ProcessInstances with an empty variables Map, it is set to null. But if I put any value, I works fine. This below code show this behavior. Uncomment the "vars.put("uno", "dos");" line to see it return a the right map when it is not empty. JbpmContext jbpmContext = JbpmConfiguration.getInstance().createJbpmContext(); try { HashMap<String, String> vars = new HashMap<String, String>(); //vars.put("uno", "dos"); ProcessDefinition pd = ProcessDefinition.parseXmlString( "<process-definition>" + " <start-state>" + " <transition to='s' />" + " </start-state>" + " <state name='s'>" + " <transition to='end' />" + " </state>" + " <end-state name='end' />" + "</process-definition>" ); ProcessInstance pi = pd.createProcessInstance(vars); TaskMgmtInstance tmi = pi.getTaskMgmtInstance(); tmi.createStartTaskInstance(); System.out.println("Created ProcessInstance Variables: "+pi.getContextInstance().getVariables()); } catch (Exception e) { e.printStackTrace(); } finally { jbpmContext.close(); }
