RemoteObject / ComboBox

[GeorgeWS]

I am having trouble filling in a combobox with my
remoteobject. Im thinking I need to retrieve the RO into an
ArrayCollection. but im not sure how this would look. Can someone
show me a sample? In my app if I hard code an array with data and
labels it works fine.



I have a RO like:



<mx:RemoteObject id="Brands" destination"COLDFUSION"
source="Inv" showBusyCursor="true"/>



I have a ComboBox:



<mx:comboBox id='brandfilter'
dataprovider="{Brands.Brands.data}"/>



I have a CFC:



<cffunction name="Brands" access="remote"
returnType="query" output="false">

<cfquery name="Brands" datasource="myDatasource">

Select distinct brandid as data , branddesc as label

From Inv

</query>

<cfreturn Brands>

</cffunction>

HI,



We just tried returmType= query to fill the combobox without
any issue. What did you get in you combobox? You saw [object
object] or nothing at all

yes i get [object object]. Im thinking that I need to call
out the RO with the creationcomplete to my initVars function. but
not sure. Im having a hard time making a new project to test
this.

Hi



If you see [Object Object], i believe if is the labelField
problem. Please turn on debug to see the property name is lowercase
"label" . Otherwise, you have to add labelField to your combobox

You had know issues? Can you show me you code. or what you
did to fill the ComboBox. i cant get the syntax right.

Hi,



This is how the labelField work.

<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
creationComplete="initApp()">



<mx:Script>

<![CDATA[

import mx.collections.*;



public var mylist:Array ;

private function initApp():void

{

mylist = [ {LABEL:"a",data:[{label:"a1",data:1},
{label:"a2",data:2},{label:"a3",data:3}]},

{LABEL:"b",data:[{label:"b1",data:1},
{label:"b2",data:1},{label:"b3",data:1}]},

{LABEL:"c",data:[{label:"c1",data:1},
{label:"c2",data:1},{label:"c3",data:1}]},

{LABEL:"d",data:[{label:"d1",data:1},
{label:"d2",data:1},{label:"d3",data:1}]}] ;

cb.dataProvider = new ArrayCollection(mylist);

}

]]>

</mx:Script>

<mx:ComboBox id="cb" labelField="LABEL" />

<mx:List id="listbox" width="100"
dataProvider="{cb.selectedItem.data}"/>

</mx:Application>



However, it still has to verify the data from your remote
call. You can turn on debug by modifying
WEB-INF/flex/services-config.xml

<target class="flex.messaging.log.ConsoleTarget"
level="Debug">

Then, you should able to see the debug messages, you can find
the actual data type and the properties. or If you are using debug
player, add <mx:TraceTarget /> to your mxml file. You should
able to see the deserialization message log on flashlog.txt

Thanks,

It not really the combobox that is not working. I want to
know how to get the RemoteObject into and Array so there is a
label: and data:. I know that comnobox works because if I hard code
and Array like you have done the ComboBox works fine. I just cant
find anywhere how to make, get , call? an Array out of the
RemoteObject (also that I know works) and has the 2 fields in the
CFC renamed to data and label. Any thoughts would be great

HI,



I overlooked your code. I thought it was data problem! I
should read through you code! Sorry!

I think you didn't make a remote procedure call. you should
call it before you can get the result

You have to call Brands.Brands.send() , you can call it in
creationComplete



then you should get it to work with the lastResult property

<mx:comboBox id='brandfilter'
dataprovider="{Brands.Brands.lastResult}"/>
