I want to use Seam built-in components to deploy a xml file with a process definition. My
code:
| @Name("workflowHome")
| @Transactional
| public class WorkflowHome extends EntityHome<Workflow>
| {
|
| @RequestParameter
| Long workflowId;
|
| private Workflow workflow;
| @In(required=false)
| Discipline discipline;
| @In(value="org.jboss.seam.core.jbpm")
| private Jbpm jbpm;
|
| @In(value="org.jboss.seam.core.jbpmContext",create=true)
| private JbpmContext context;
|
|
| @Override
| public Object getId()
| {
| if (workflowId==null)
| {
| return super.getId();
| }
| else
| {
| return workflowId;
| }
| }
|
| @Override
| public void create() {
| super.create();
|
| }
|
| @Factory("workflow")
| public Workflow initWorkflow(){
| return getInstance();
| }
|
| protected Workflow createInstance() {
| workflow = new Workflow();
| discipline.getWorkflows().add(workflow);
| return workflow;
| }
|
| public void deployProcess(){
| String file = new String(workflow.getWorkflowFile());
|
| try{
| context.deployProcessDefinition(jbpm.getProcessDefinitionFromXml(file));
| }finally{
| context.close();
| }
| }
|
| }
|
What am I missing? Because I'm getting the following exceptions:
| 03:08:44,372 ERROR [PhaseListenerManager] Exception in PhaseListener
RENDER_RESPONSE(6) beforePhase.

Everything works fine if I deploy the process definition if I use this code instead:
| String name=null;
| JbpmContext jbpmContext=null;
| String file = new String(workflow.getWorkflowFile());
| ProcessDefinition processDefinition = ProcessDefinition.parseXmlString(file);
|
| JbpmConfiguration jbpmConf = JbpmConfiguration.getInstance();
| jbpmContext = jbpmConf.createJbpmContext();
|
| try {
| jbpmContext.deployProcessDefinition(processDefinition);
| } finally {
| jbpmContext.close();
| }
|
I'd rather use the Seam components. I've been loonking for some similar problems
in the forum and I don't know if it is the same problem as in
http://jira.jboss.org/jira/browse/JBSEAM-798. If only anyone could help me!
