[jboss-user] [JBoss Seam] - Re: Beginner: Bind SelectOneMenu to @onetoone entity object

[lazar.mihai]

To be honest I'm glad you opened up the discussion regarding <h:selectOneMenu ...
I'm trying to do something like this
<h:selectOneMenu id="idCurs" value="#{cursHome.instance.idcurs}">
  | 				<s:selectItems  value="#{cursList.resultList}" label="#{curs.nume}" 
  | 				var="curs"				
  | 				noSelectionLabel="Alege un curs"
  | 				/>
  | 				<s:convertEntity  />
  | 				<a:support event="onblur" reRender="idcursDecoration" bypassUpdates="true"/>
  | 			</h:selectOneMenu>

I have StudentHome the student ( generated with seam generate entities), and I want it to return the id of a selected item in the option list.

I already did the override on equals and hashCode and read the wiki and other posts on the matter but I don't fully understand how the hole thing is supposed to work.

It gets the list from the cursList.resultList. Then when I select an item .. he does what exactly ? he sets the value of var to whatever I say in the <h:selectOneMenu ? or where

I would like for it to set the value of the current edited studentHome.instance.idcurs to the value of idcurs from the selected item in the list.. something like binding the label value to curs.nume and the value to curs.idcurs 

Any suggestions or other ways of accomplishing this ?
