5:03 a.m.
So I created a process by means of the @CreateProcess annotation
@Stateful
@Name("createOrder")
public class CreateOrderImpl implements CreateOrder, Serializable {
@Logger
Log log;
............................................
@CreateProcess(definition="order issuing")
public void startWorkflow() {
log.debug("workflow started 'orderIssuing'");
}
............................................
@Destroy
@Remove
public void destroy() {
}
}
The process defenition is
<?xml version="1.0"?>
<process-definition name="order issuing">
<start-state name="start">
</start-state>
<task-node name="create order">
<assignment pooled-actors="inspectors"/>
<!--assignment actor-id="#{actor.id}"/-->
</task-node>
<task-node name="deans sign">
<assignment pooled-actors="deans"/>
<!--assignment actor-id="#{actor.id}"/-->
</task-node>
<task-node name="lawyers sign">
<assignment pooled-actors="lawyers"/>
<!--assignment actor-id="#{actor.id}"/-->
</task-node>
<end-state name="end"></end-state>
<task-node name="correct document">
<assignment pooled-actors="inspectors"/>
<!--assignment actor-id="#{actor.id}"/-->
</task-node>
</process-definition>
Then I output tasks for current actor
<h:dataTable value="#{pooledTaskInstanceList}"
var="task"
styleClass="dvdtable"
headerClass="dvdtablehead"
rowClasses="dvdtableodd,dvdtableeven"
columnClasses="dvdtablecol">
<h:column>
<f:facet name="header">??????</f:facet>
<h:outputText value="#{task.description}" />
</h:column>
<h:column>
<f:facet name="header">??????</f:facet>
<h:outputText value="#{task.create}" />
</h:column>
<h:column>
<f:facet name="header">????</f:facet>
<h:outputText value="#{task.variables['file'].name}" />
</h:column>
<h:column>
<s:link action="#{pooledTask.assignToCurrentActor}"
taskInstance="#{task}" value="????????"
linkStyle="button"/>
</h:column>
</h:dataTable>
And if you click on <s:link.../> you will redirected to upload.xhtml by means of
navigation rule
</faces-config>
..............
<navigation-rule>
<navigation-case>
<from-action>#{pooledTask.assignToCurrentActor}</from-action>
<from-outcome>taskAssignedToActor</from-outcome>
<to-view-id>/upload.xhtml</to-view-id>
</navigation-case>
</navigation-rule>
..............
</faces-config>
Here is the page source

and its backing bean
@Name("taskManager")
public class TaskManagerImpl {
@Logger
Log log;
public String getTest() {
return "test";
}
@Create
@StartTask
public void startTask() {
log.debug("task started");
}
@EndTask
public void endTask() {
log.debug("task ended");
}
}
Now the problem is that the following exception occures while TaskManagerImpl.startTask()
invocation
