Error Starting Taks With Jbpm
Hello,
I'm working with a Seam project and recently I needed to add jbpm process definitios to it. so I refered to the example TodoList, the matter is that I have followed the steps to confiugred the project. The process is created correctly with a warn:
"Narrowing proxy to class org.jbpm.graph.node.TaskNode - this operation breaks =="
When i want to start or end a task I get an error on the application, but on the console (or log) it shown nothing, so I don't know what happens. Here is my code:
I have three methods in the bean:
@Name("tareaEnrolamientoBB")
@Scope(ScopeType.SESSION)
public class TareaEnrolamientoBB extends GestionTekBackingBean {
private static final long serialVersionUID = -922289055419074L;
@Logger
private Log log;
@PostConstruct
public void constructor() {
System.out.println("===== ENTER CONSTRUCTOR ====");
}
@CreateProcess(definition="enrolamiento")
public void iniciarProceso(){
}
@EndTask
public String completarTarea() {
return null;
}
@StartTask
public String empezarTarea(){
return null;
}and in the view:
<h:dataTable
value="#{taskInstanceList}" var="task"
rendered="#{not empty taskInstanceList}">
<h:column>
<f:facet name="header">
<h:outputText value="Description" />
</f:facet>
<h:inputText value="#{task.description}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Created" />
</f:facet>
<h:outputText
value="#{task.taskMgmtInstance.processInstance.start}">
<f:convertDateTime type="date" />
</h:outputText>
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Priority" />
</f:facet>
<h:inputText value="#{task.priority}" style="width: 30" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Due Date" />
</f:facet>
<h:inputText value="#{task.dueDate}" style="width: 100">
<f:convertDateTime type="date" dateStyle="short" />
</h:inputText>
</h:column>
<h:column>
<s:link value="Start" action="#{tareaEnrolamientoBB.empezarTarea}"
taskInstance="#{task}" linkStyle="button" />
</h:column>
<h:column>
<s:link value="Done" action="#{tareaEnrolamientoBB.completarTarea}"
taskInstance="#{task}" linkStyle="button" />
</h:column>
</h:dataTable>the button for starting process:
<h:commandButton action="#{tareaEnrolamientoBB.iniciarProceso}"
styleClass="btnNaranja" value="Registrar" />ANY HELP WELCOMED!!!! THANKS!!
