Flex: RemoteObject, passing named parameters - apache-flex

Question

I'm calling ColdFusion cfc method using RemoteObject method of the Flex.
<fx:Declarations>
<s:RemoteObject destination="ColdFusion" source="cfc.categoryGateway" id="categoryGateway">
<s:method name="getCategoryList" result="returnHandler(event)"
fault="mx.controls.Alert.show(event.fault.faultString)">
<s:arguments>
<orderby>categoryId</orderby>
<parentCategory>1</parentCategory>
</s:arguments>
</s:method>
</s:RemoteObject>
</fx:Declarations>
Where as my cfc accepts the parameter in following manner:
<cffunction name="getCategoryList" access="remote" output="false" returntype="query">
<cfargument name="parentCategory" type="string" required="false" />
<cfargument name="orderby" type="string" required="false" />
<!--- code... --->
<cfreturn qCategoryList />
</cffunction>
So you can see that I changed the sequence of the parameter, when I call the cfc method. But it does not worked.
It means that <s:arguments> does not pass the named parameter.
Is there any solution for that? As you can see that I may have some of the arguments not mandatory so, it must be passed by name.

Answer 1

The arguments parameter is an array, so regardless of what you name each element, I think it will still use it in order.
You can try doing something like this instead:
<s:RemoteObject destination="ColdFusion" source="cfc.categoryGateway" id="categoryGateway">
<s:method name="getCategoryList" result="returnHandler(event)"
fault="mx.controls.Alert.show(event.fault.faultString)" />
</s:RemoteObject>
then call:
categoryGateway.getCategoryList({orderby:'categoryId', parentCategory:'1'});
