No Results after executing Adaptive Web Service

Question

Hello experts,
I develope Web Dynpro applications and currently try to consume a web service from our ERP system but I get no results from the service. When trying to consume the service with a soap-tool or with .NET, everything works fine.
The Web Service was generated on an already available RFC.
The service has one input parameter, which is a department name. The output should be all employees, which work in the consigned department.
For consuming the service I created a Web Service Destination in the Visual Administrator ([see this blog|http://www.sdn.sap.com/irj/scn/weblogs;jsessionid=%28J2EE3417100%29ID0139461950DB10406225565548708901End?blog=/pub/wlg/5186]).
After creating the Destination I imported the service as an adaptive web service model in my web dynpro project.
After binding the model to the component controller I implemented the following code in the controller:
public void wdDoInit()
    model = new Z_WF_DEPARTMENT_OIC();
    Request_ZWfDepartmentOic requestMO = new Request_ZWfDepartmentOic(model);
    ZWfDepartmentOic departmentMO = new ZWfDepartmentOic(model);
    requestMO.setZWfDepartmentOic(departmentMO);
    wdContext.nodeRequest_ZWfDepartmentOic().bind(requestMO);
public void executeRequest_ZWfDepartmentOic( )
  try{
    wdContext.currentRequest_ZWfDepartmentOicElement().modelObject().execute();
    wdContext.nodeResponse().invalidate();     
  } catch (Exception e) {
    wdComponentAPI.getMessageManager().reportException(e.toString(),false);
I did the implementation as descibed in the following document:
[http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/900bbf94-a7a8-2910-e298-a651b4706c1e&overridelayout=true]
On the UI I have one input field for the department name and a table which should show the result and one table which shows messages which are returned by the web service.
After executing the code, I get no result from the service. In my table with the messages I get one entry which just shows zeros in the fields "LogMsgNo" and "Number".
Does anybody have a hint, what could be wrong with my proceeding?

Check this blog post:
http://www.drflex.eu/2008/06/dynamically-populate-dropdown-lists-using-webservices/
This comfirms that after you execute a web service, the Drop-Down List fields will become empty due to remerge operation. Well, I have to issue a remerge, otherwise, the PDF will not be populated properly.
