RE: [flexcoders] lcds 2.5.1, Map Java-to-AS serialisation make Integer values null

[Jeff Vroom]

We currently do not have support for serializing Java 1.5 enums though
so that might be the problem.  Would it be easy for you to try using
String based keys instead?

Integer values null

 

My Java server side, service and resulting Event object:

public class StatsEventRepresentationServiceImpl {
    public List<Event> getStats(Date start, Date end) {...}
}

public class Event {
    public Date ts;

    public Map<Type, Integer> typeFacts;
    ...
}

remoting-config.xml:

<service id="remoting-service"
class="flex.messaging.services.RemotingService">
<adapters>
    <adapter-definition id="java-object"
class="flex.messaging.services.remoting.adapters.JavaAdapter"
default="true"/>
</adapters>

<default-channels>
    <channel ref="my-amf"/>
</default-channels>

<destination id="statsService">
    <properties>
        <factory>spring</factory>
        <source>statsBean</source>
     </properties>
</destination>
</service>

Channel definition:

<channels>
<channel-definition id="my-amf"
class="mx.messaging.channels.AMFChannel">
    <endpoint
url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf
" <http://%7bserver.name%7d/%7Bcontext.root%7D/messagebroker/amf> 
            &! nbsp;   class="flex.messaging.endpoints.AMFEndpoint"/>
    <properties>
        <polling-enabled>false</polling-enabled>
    </properties>
</channel-definition>
...

At client side I've got null on the place of Event.typeFacts that in
fact are filled with some Integer values in
StatsEventRepresentationServiceImpl.getStats(). I've enabled lcds
logging to find out problematic place and got this:

[Flex] After invoke service: remoting-service

Why lcds sterilizes Map<Enum, Integer>'s values as nulls? Some problem
with configuration? Lcds bug?
