This line cause the problem:
wdContext.currentxxxxxElement().modelObject().execute();
More information on the implementation:
try {
          wdContext.currentRequest_CalNganViDocument_changeCaseElement().modelObject().execute();
          wdContext.nodeResponse().invalidate();
                    String result = wdContext.currentResponseElement().getResult();
          wdComponentAPI.getMessageManager().reportSuccess(result);
catch(Exception ex) {
          wdComponentAPI.getMessageManager().reportException(ex.getLocalizedMessage(),true);

here is the code in ini method:
//@@begin wdDoInit()
     Request_CalNganViDocument_changeCase req = new Request_CalNganViDocument_changeCase();
     wdContext.nodeRequest_CalNganViDocument_changeCase().bind(req);//   nodeWebServiceEmail().bind(req);
    //@@end
and the action of button:
//@@begin onActionsend(ServerEvent)
     try {
          wdContext.currentRequest_CalNganViDocument_changeCaseElement().modelObject().execute();
          wdContext.nodeResponse().invalidate();
     //     String result = wdContext.currentResponseElement().getResult();
     //     wdComponentAPI.getMessageManager().reportSuccess(result);
     wdComponentAPI.getMessageManager().reportSuccess("dala");
     catch(Exception ex) {
          wdComponentAPI.getMessageManager().reportException(ex.getLocalizedMessage()+"no method",true);
    //@@end
