You add these optional serialization properties in the <channel-definition> in
your services-config.xml file that your client is using to communicate with the
server.
These settings are specific to the channel/endpoint they're defined for (i.e.
not global).
So something like:
...
<channel-definition id="my-amf" class="mx.messaging.channels.AMFChannel">
<endpoint
url="http://{server.name}:{server.port}/{context.root}/messagebroker/amf";
class="flex.messaging.endpoints.AMFEndpoint"/>
<properties>
<serialization>
<ignore-property-errors>false</ignore-property-errors>
<log-property-errors>true</log-property-errors>
</serialization>
</properties>
</channel-definition>
...

Subject: [flexcoders] Re: Sending data to the Server
Hey my bad, I just found out I was not instantiating my AxisObject class
correctly on the
flex side. So I can pass the variables find now. However I would still like to
figure out how
to turn on the warning messages in the config files so that in the future I can
hopefully
catch mistakes like this much quicker. If you have time and could post maybe a
more
complete sample along with which files you need to update, I'd appreciate it.
Thanks for the help.
