Problem to call an annotated method from another component

[coolex]

Hallo all!

I have a class that manages my running processes

@Name("processManager")
public class ProcessManagerBean implements ProcessManager{
    ...

    @BeginTask
    @EndTask
    public String endTask(){
     return "taskEnded";
    }
    ...
}

And I have another class (TestClass) that wants to use this processManager.endTask() method

@Name("testing")
public class TestClass {
     
     @In(value="#{processManager}")
     ProcessManager processManager;
     
     public void endCurrentTask(){
          processManager.endTask();
     }
     
}

First problem is that without

(value="#{processManager}")

my TestClass is not injected with the processManager even it is used before. I get NullPointerException.

The main problem is that I cannot call the method processManager.endTask() in my TestClass like you can see here

public void endCurrentTask(){
    processManager.endTask();
}

Then I get this error:

task/process id may not be null"

I thought I need the processId and the taskID to solve the problem, so I added this variables to my processManager:

   @RequestParameter("processId")
    private String processId;

    @RequestParameter("taskId")
    private String taskId;
    

Hope you can help me!
Thanks in advance.
