ColdFusion 9: CFSELECT + BIND + Selected Attribute Work Together Now?

In case you have been living under a rock like me, it seems the selected attribute works with bound cfselect lists.


Form

<cfparam name="form.foodID" default="0">

<cfform method="post" action="#CGI.SCRIPT_NAME#">
    Favorite Food: 
                <cfselect name="foodID"
                    value="foodID"
                    display="FoodName"
                    selected="#form.foodID#"
                    bind="cfc:Food.getFood()"
                    bindOnLoad="true"
                />
    <cfinput type="submit" name="submitMe" />
</cfform>

Food.cfc
<cfcomponent output="false">
   
   <cffunction name="getFood" access="remote" output="false" returntype="query">
      <cfset var q    = QueryNew("") />
      <cfset queryAddColumn(q, "FoodID", "integer", listToArray("0,1,2,3")) />
      <cfset queryAddColumn(q, "FoodName", "varchar", listToArray("-Pick Something-,Burger,Pizza,Lasagna")) />
      <cfreturn q />      
   </cffunction>
   
</cfcomponent>

Wow! Didn't try it, but I lost my hair trying on CF8. Thanks for the tip!

Thanks for posting this, its good to know its working in 9. Unfortunately we are stuck on 8 for a couple more months. Is there a simple interim solution for the bug in 8?

Not a bug. But not supported either. Though I agree it should be ;)

Unfortunately, I do not know of any one-liners. But here are two options:
