Populate data in dropdown

Question

Hi All,
I am trying to populate values in dropdown by calling
BAPI. I have only one view in my applicaiton.
I created a model in custom controller and bind it to   the model.
I defined the context (model node) in view controller same stucuture in custom controller and mapped the context between view controller and custom controller.
Model node
Zemployee2_Input
   Output
     TEmployee
       Empname
       Empno
Value attribute
    empCode
I created a Template( table) and bind with the view context.
When I deployed the application, the table was displaying 32 records.
I have a problem to populate values in the dropdown.
I created value attribute called empCode in View contr.
I bind the attribute to the value property of dropdown
called dropdownEmployee.
issue#1:
int nodeSize =  wdContext.nodeZemployee2_Input().size();
In runtime
nodeSize has 1.
But it supposed to have 32.
issue#2:
((IPublic<controller_name>.I<node_name>Element)(wdContext.node<node_name>().getElementAt(i))).get<attribute_name>());
What is get<attribute_name> ?
As per my model nodes,
I wrote this code like,
((IPublicTestCustom.IZemployee2_InputElement)(wdContext.nodeOutput().getElementAt(i))).?
after this,
Intellisense gives me 3 options to select,
getAttributeAsText();
getAttributeValue();
getClass();
Where do i select get<attribute_name> ?
Please give me a solution for this.
Thanks

Hi,
int nodeSize = wdContext.nodeZemployee2_Input().size();
  As Table showing 32 records, dropdownlistbox also show the same records. Have bind the table to same node or different one?
  I have pasted code to you, which is working fine with me. try to make use of it.
Create a context Variable in your View with empcode.
empCode - whichever you want to see in the DropDownListByKey.
IContextElement contextElement = wdContext.currentContextElement();
IWDNodeInfo nodeInfo = wdContext.getNodeInfo();
IWDAttributeInfo dateAttributeInfo = nodeInfo.getAttribute(contextElement.empCode);
IModifiableSimpleValueSet dropValueSet = dateAttributeInfo.getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();
String empCodeTxt=null;
//Gives the Size of the List, which is coming from Model
int nodeLength = wdContext.node<BAPIList>().size();
for (int i = 0; i < nodeLength; i++) {
// Gives the Value, Which you want to show in Drop Down List Box.. Change it according to your need.
empCodeTxt=String.valueOf(((IPrivate<viewname>.I<BAPIList>Element)(wdContext.node<BAPIList>().getElementAt(i))).get<Parameter>());
dropValueSet.put(empCodeTxt, empCodeTxt);
