Dropdown List Web dynpro Abap

Question

Hi All
I am new to adobe forms.  I am having a problem with populating drop down list box on an adobe interactive form.  I have gone through this forum and I have tried a number of different things but nothing seems to work.
When I run my web dynpro application the drop down looks like an input box.  There is no down arrow icon on the side.
I check note 981638.  It states it can't be implemented.
I am on CRM 2007 NW7 platform.
I created an interface with an importing value called it_dropdown.  this is a table.
I created a form that uses this interface.
i placed a drop down list on the form layout.  In the dynamic options i click list items.  I get a popup.
In the bindings I bind to the table... $record.IT_DROPDOWN.DATA[*]
The text and value are bound to corresponding fields on the internal table.
I created a webdynpro
I created a view.
I poped an interactive form ui elemnt on the view.
I generated the context.
I checked the cardinality of the node for the internal table and it is 0..n
In my doinit method I have the following code.
  data: lr_form_node type REF TO if_wd_context_node.
  data: lr_dd  type REF TO if_wd_context_node.
  data: lt_dropdown  type WDR_CONTEXT_ATTR_VALUE_LIST,
           wa like line of lt_dropdown.
  do 20 times.
    wa-value = sy-index.
    concatenate 'Test' wa-value into wa-text SEPARATED BY space.
    insert wa into table lt_dropdown.
  enddo.
lr_form_node = wd_context->get_child_node( wd_this->wdctx_zfp_example_01 ).
lr_dd = lr_form_node->get_child_node( wd_this->wdctx_it_dropdown ).
  lr_imp->bind_table( lt_dropdown ).
The adobe form displays but the drop down is not populated.
I have tried a normal drop down and webdynpro enumerated drop downs.
Can someone please point out what I am doing wrong.
Thanks
Darren

Hi Sachin
Here is exactly what I did.
1. Create a web dynpro application.
2. Crate a view
3. On the context create a node called data_source or whatever you want.  The cardinality is 1.1.
4. Create an attriubute on the data_source note.  I called mine 'DDOWN' and created it as a string.
5. Pop an interactive form element on your view.
6. In the Template Source, give the name of your adobe form.  This part was the vital bit for me as I was using a database interface originally and I think that this was my problem.  If you already have a form created that does not use xml, I would advise you to create a new temporary adobe form by putting the name in the template source and double clicking it.
7. You will get a popup stating asking you to create an interface.  You will see a button called "context" click this and follow the steps.
8. When you get to your form you will see the drop down context node in the data hierarchy.  Drop a drop down list on your form and then drag and drop your context node onto it.  Make sure your forms layout is ZCI. Save the form.
9 Return to your web dynpro app.  You will see that the datasource has been updated. 
10.  I used the following code in the doinit method of the web dynpro.
  data: lr_context_node type ref to if_wd_context_node.
  data: lt_dd type wdr_context_attr_value_list.
  DATA: node_info TYPE REF TO if_wd_context_node_info.
  data: wa like line of lt_dd.
  do 20 times.
    wa-value = sy-index.
    concatenate 'Test' wa-value into wa-text SEPARATED BY space.
    insert wa into table lt_dd.
  enddo.
  lr_context_node = wd_context->get_child_node( name = 'ZDARREN1' ). "Template Source
  node_info = lr_context_node->get_node_info( ).
  node_info->set_attribute_value_set(
     name      = 'DDOWN'                                      "DDOWN is a node on the context
     value_set = lt_dd ).
Activate and test.
You should see a dropdown.
I hope this helps as this is the approach that worked for me.
