how to access process variable
Hi guys,
I have a problem to access the process variable fahrgestellNummer stored in jbpm variableinstance after exending todoList example for testing.
The variabel is stored by the class
@Name("todoList")
public class TodoList
{
private String description;
@In(value="#{vert.fahrgestellNr}", scope = ScopeType.BUSINESS_PROCESS)
@Out(scope = ScopeType.BUSINESS_PROCESS, required=true)
long fahrgestellNummer;
@In private Actor actor;
@In private JbpmContext jbpmContext;
public String getDescription()
{
return description;
}
public void setDescription(String description) {
this.description = description;
}
@CreateProcess(definition="todo")
public void createTodo() { +fahrgestellNr);
System.out.print("=> => => => fahrgestellNummer: " +fahrgestellNummer);
taskStarten();
}
@StartTask
public void taskStarten() {
System.out.print("=> => => => in taskStarten");
System.out.print("=> => => => fahrgestellNummer: " +fahrgestellNummer);
}
@EndTask
public void done() {}
}Within the form fahrgestellNummer seems to be empty because there is no output:

<h:outputText value="fahrgestellNummer"/>

<h:outputText value="#{var['fahrgestellNummer']}" style="width: 400"/>
</h:column>Has somebody an idea what is wrong?
Thanks Tina
