Problem with Flamingo and Seam
backov Jun 11, 2008 10:58 PMI'm hoping this is an ok place to post this, I've been ramping up on Seam/Hibernate/EJB3/etc for over a week now in my spare time trying to convert a RoR backend to Seam. I've been reading every book I can get my hands on, 4 Apress and OReilly books so far, but I'm still not there.
I've just got a little test app running, and I'm trying to return an entity to the Flex app and getting some problems.
I want to return an entity bean from a query - the hibernate part is working, I can return a string and it works fine.. when I try to actually return the object it chokes. I've mapped the object like so:
package com.tamedtornado { [RemoteClass(alias="com.tamedtornado.data.Players")] [Bindable] public class PlayersMapping { public function PlayersMapping() { } public var Player_id:int; public var Name:String; } }
Now that doesn't represent the entire object, just a couple of fields on it. I'm not sure if that's an issue, as it doesn't say anything about that in the Flamingo docs. I've also tried it with a 2 field dummy object and get the same exception, so I assume that is not the problem.
Now, when I hit the service I use this method in the bean:
public Players getPlayer() { return em.find(Players.class, 618895041); }
Which should be returning me my entity class. If i modify that routine to return that players name, it works fine.
The exception I get is this:
TypeError: Error #1034: Type Coercion failed: cannot convert mx.rpc::AsyncToken@af50941 to com.tamedtornado.PlayersMapping. at TestFlex/getPlayer()[D:\JavaProjects\TestFlex\src\TestFlex.mxml:13] at TestFlex/___TestFlex_Button1_click()[D:\JavaProjects\TestFlex\src\TestFlex.mxml:32]

I feel like I'm getting close here, any help would be appreciated. :)
