I am returning an Array of typed objects from Java. Say the typed object
is X so essentially an Array of X objects. The typed object X internally
contains another typed object Y which then contains an ArrayList of
typed Object Z. My first question is do these complex nested objects get
properly serialized on the ActionScript/Flex end properly. Is it
recommended to have such deep nesting while returning these complex
objects from the Java end.
I am able to retrieve attributes of primitive types such as Strings
directly under object X. However I am not sure how to retrieve object Y
and the nested ArrayList of Z objects that Y contains. This is how my
setup is
=====================================================================
[Bindable]
[RemoteClass(alias="abc.def.Y")]
public class Y_DTO
{
/**
* A collection of zero or more Z objects
*/
[ArrayElementType ("Z_DTO")]
public var zObj:ArrayCollection;
public function Z_DTO()
{
zObj = new ArrayCollection();
}
}
======================================================================
======================================================================
[Bindable]
[RemoteClass(alias="abc.def.Z")]
public class Z_DTO
{
/**
* The name of the column being filtered
*/
public var columnName:String;
public function Z_DTO(){
}
}
}
======================================================================
======================================================================
[Bindable]
[RemoteClass(alias="abc.def.X")]
public class X_DTO
{
public var userName : String;
/**
* The list of filters used in the search.
*/
public var yObj:Y_DTO;
public function X_DTO()
{
yObj = new Y_DTO();
}
}
======================================================================
Finally in my MXML file I have this method that tries to read these
objects:
======================================================================
private function getXYZSuccess(event : ResultEvent):void
{
var result:Array = (event as ResultEvent).result as Array;
xyc = new Array();
if (result)
{
for each(var item:Object in result)
{
xyc.push(X_DTO(item));
Alert.show("SearchPreferences
:"+this.xyz.userName+"\n"+ this.xyz.yObj.zObj.columnName+"\n"+
}
}
}
=======================================================================
this.xyz.yObj.zObj.columnName returns null. Can you tell me how I can
access the object Y_DTO and Z_DTO and their respective elements. What am
I missing here?
any suggestions, comments will be warmly appreciated.
regards
