How can I make a bound drop-down list using OAF?

Question

Please note, this is for OAF. I am aware of the support in ADF.
I'm sorry this is such a basic question, but I've been trying for days, and I can't think of anywhere else to look for an answer.
I need a simple drop-down list, not a search. This particular list only has 10 or so items. It is based on a view containing a code value, and a description. I need all descriptions to be available at all times. Just click the arrow, and the entire list is displayed. When the user selects an entry, the code associated with the discription populates a bound attribute. Ideally, when the page is instantiated, the code value controls the text value visible in the collapsed drop-down list. Visually, it would be similar to an html <select> element.
Can someone please tell me how I can produce such a simple thing, or point me to some documentation?
Thank you.

Thank you for the excellent reference Peddi. I had played with the OAMessageChoiceBean component yesterday, but I was able to tell from your instructions that "Picklist Display Attribute" and "Picklist Value Attribute" really are not for binding to the database EO. That was the key piece of information that had me confused.
In addition to adding the messageChoice component to the page, I needed to write some code to synchronize the picklist value with the corresponding code value, which I placed in am OAFormValueBean (hidden form field) which I could then bind to my application's database EO in the controller, running in the processFormRequest procedure:
/** Synchronize the catalog code with the selected catalog name */
protected void syncCatalogValues(OAPageContext pageContext,
OAWebBean webBean, MyApplicationAMImpl am) {   
OAMessageChoiceBean mcb =
(OAMessageChoiceBean) webBean.findChildRecursive("CatalogName");
OAFormValueBean cc =
(OAFormValueBean) webBean.findChildRecursive("CatalogCode");
String catalogDescription = mcb.getText(pageContext);
if (catalogDescription != null) {
String catalogCode = am.getCatalogCode(catalogDescription);
cc.setValue(pageContext, catalogCode);
Along with a little code to get the catalogCode value from the LOVVO, that's all it took.
Thanks again. This was a great help.
