Missing declared association property

Question

A fill command like so:
<mx:Button label="Fill" click="{se.fill(entitymaps)}"/>
In this data service:
<mx:DataService id="se" destination="entityds"/>
Gives the following stack trace:
Error: Item added to destination: entityds of type: maps::EntityMap is missing declared association property: children

When the 'children' property of EntityMap is not declared, EntityMap looks like this:
package maps
    import mx.collections.ArrayCollection;
    [Managed]
    [RemoteClass(alias="alex.onetomany.Entity")]
    public class {   
        public function EntityMap() {}      
        public var name:String;
        public var identity:String;
Despite the fact that the entityds destination looks like this......
<destination id="entityds">
        <properties>
            <source>alex.onetomany.EntityAssembler</source>
            <scope>application</scope>
            <metadata>
                <identity property="identity"/>
            </metadata>
            <network>
                <paging enabled="false" pageSize="10" />
            </network>
        </properties>
    </destination>
...the problem still seems to occour. The strangest thing is when I rename the destination from entityds to 'blah' (on the server in data-management-config.xml and on the client in my MXML file OneToManyTest.mxml) the error no longer happens.
Questions:
1) When exactly is the missing declared association property: supposed to appear? Is it when you add some associated property in data-management-config.xml, if so....
2) How come it does not appear for the nodeds data service when I give it a similar children property on-to-many configuration in data-management-service.xml like so:
    <destination id="nodeds">
        <properties>
            <source>alex.onetomany.NodeAssembler</source>
            <scope>application</scope>
            <metadata>
                <identity property="identity"/>
                <one-to-many property="children" destination="nodeds"
                    load-on-demand="true"
                    read-only="true"
                    lazy="false"/>
            </metadata>
            <network>
                <paging enabled="false" pageSize="1" />
            </network>
        </properties>
    </destination>
3) Most importantly: why does it appear for entityds and only when the destination is called entityds and nothing else.

Answer 1

Do you have the XML request that you are sending?
