Node Binding Error

Question

Hello,
I am on EP7.0 ERP05 NW04s and trying to modify the ESS Address applicaion to point to a custom Function Module ,I changed the Model Bindings for that matter but when I try to execute the application I get the following error during runtime:
com.sap.tc.webdynpro.progmodel.context.ContextException: Node(FcPerAddressUS.NewInfotype.Ouput.NewRecord): cannot bind or add elements because the node has no valid parent

I wonder for the cause for this.
Any help would be highly appreciated..

Dear Uday,
Please try this :-
Zhr_Str_Employee_Rel eno = new Zhr_Str_Employee_Rel(WDModelScopeType.APPLICATION_SCOPE);
wdContext.nodehr_Str_Employee_Rel().bind(eno);
eno.setEmp_No(<PASS THE VALUE TO MODEL FOR EXECUTION>);
try
     eno.execute();               
     wdContext.nodeOutput_username().invalidate();                                             
}catch(WDDynamicRFCExecuteException ce) {
     wdComponentAPI.getMessageManager().reportException("executing Model:: "+ce.getMessage(),false);
}catch(Exception ex){               
     wdComponentAPI.getMessageManager().reportException("executing Model:: " +ex.getMessage(),false);
}finally{     
     // Copy Results into IIt_Emp_NoNode Node:                     
     populateIt_Emp_No();
                     //Disconnect model instance
     wdContext.currentZhr_Str_Employee_RelElement().modelObject().modelInstance().disconnectIfAlive();     
//Create method to populate the value in It_Emp_No
populateIt_Emp_No(){
     wdContext.nodeIt_Emp_No().invalidate();
     IIt_Emp_NoElement eleEmp = null
     if(wdcontext.nodeOutput_username().size() > 0){
          for(int i=0; i<wdcontext.nodeOutput_username().size(); i++) {
               eleEmp = wdContext.createIt_Emp_NoElement();
               eleEmp.set<YOur Attribute to set>(wdContext.nodeOutput_username ().getOutput_usernameElementAt(j).getEmp_No());
               wdContext.nodeIt_Emp_No().addElement(eleEmp);     
Hope it will helps
Best Regards
