How to addRecord in Web Dynpro to Model node (Entity Service ref)

Question

Hi,
1) I create Entity Service in CAF and try to write web dynpro Table UI for it.
2) is it possible with using Model Node? or I MUST use Value Node - Table must have possibilities for Add, Edit and Delete records.
Now I can edit, and delete records, but I can't add records with AddRecord method
Code below
  public void NewTS( )
     //@@begin NewTS()
   IServiceFacade serviceFacade;
// Add new Model object TS
   ATS ts = TSServiceProxy.create();
   ts.setDate( new Date(System.currentTimeMillis()));
   ts.getAspect().sendChanges();
   serviceFacade = CAFServiceFactory.getServiceFacade(tsDefinition.class);
// try to addRecord to Controller context     
   IWDNodeElement n = wdContext.nodeTS().createElement(ts);
   wdContext.nodeTS().addElement(n);
The error is: com.sap.caf.rt.exception.CAFBaseRuntimeException:
Aspect row is invalid for aspect:   <Aspect name="TS" >
Thx for any help

Hi Nikolai,
implement it in the following way:
wdInit()
     IAspect originalAspect = TSServiceProxy.FindByName(employee) ;
     wdContext.nodeTS().bind(originalAspect)
     //just create new attribute this java native type IAspect
     wdContext.currentContextElement().setOriginalAspect() ;
public void NewTS( )
//@@begin NewTS()
     IAspect originalAspect = wdContext.currentContextElement().getOriginalAspect() ;
        IAspectRow newTS = originalAspect.createAspectRow() ;
        newTS.setAttributeValue("date", new Date(System.currentTimeMillis())) ;
or
public void NewTS( )
     IAspect originalAspect = wdContext.currentContextElement().getOriginalAspect() ;
        IAspectRow newTS = originalAspect.createAspectRow() ;
     ITSElement tsElem = wdContext.nodeTS().getTSElementAt(originalAspect.indexOf(newTS)) ;
        tsElem.setAttributeValue("date", new Date(System.currentTimeMillis())) ;
