Populating drop down list in a table cell-urgent

Question

Hi all
I have a problem. I want to populate a dropdown list in a table cell. can anybody tell me the step by step procedure for that.
I am doing it generally. not using R/3
I am creating sub node like u have mentioned. I haven't done it using wizard.
Is there any difference in the way we populate this list?
My root node is expense. Inside that some value attributes are there. For the drop down list i've created a sub node 'extype'.
I am getting error.
it is:
com.sap.tc.webdynpro.progmodel.context.ContextException: Node(EREmpHomeView.expense.extype): cannot bind or add elements because the node has no valid parent
Following is the code i've written.
IPrivateEREmpHomeView.IExtypeElement el;
          IPrivateEREmpHomeView.IExtypeNode nd=wdContext.nodeExpense().nodeExtype();
          el=wdContext.nodeExpense().nodeExtype().createExtypeElement();
          el.setEtype("Travel");
          nd.addElement(el);
Sill i'm getting the same error
Hi Nidhideep
Error has gone with the code that Mr Anil has given. But there is no value in the List. Dropdown list is coming as a blank list.
Thanks and Regards

hi
Aparna try this code:
1. Context description at design time:
Value-Node "myNode", collection type=list, cardinality=0..n, selection=0..n
and the attribute:
Value attributes “myValue”, type="String".
2. The corresponding Java source code example that you create in the wdDoInit method of the controller implementation:
// The ISimpleTypeModifiable interface enables access to
//a data type instance that can be modified at runtime:
ISimpleTypeModifiable myType =
   wdThis.wdGetAPI().getContext.getModifiableTypeOf(“.myNode.myValue”);
//Sets the label text for this data type.
myType.setFieldLabel(“New label”)
//Sets the valid values of this data type. The individual elements are inserted
//when the put method is called and
//and the value set is filled with the appropriate
//key value pair.
IModifiableSimpleValueSet values =
   getSVService().myType.getModifiableValueSet();
values.put(“key_1”,”Mister”);
values.put(“key_2”,”Mistress”);
values.put(“key_3”,”Miss”);
