Subject: [SabreAMF] SabreAMF - Class Mapping - why function receives
	SabreAMF_TypedObject instead of registered Class
Message-ID: <468297763.20100124200948@poczta.fm>

Hi !

I'd like to ask about the class mapping problem which I cannot solve.

I have made test Flex app that calls remote service passing as an
argument TestVO object. I intended to use type hinting in the function
definition "function setData(TestVO $vo){...}" but I have received
"PHP Catchable fatal error...". Earlier I was convinced that SabreAMF_
Eric Renaun's gateway will map and invoke function with object as an
instance. So I have started to dig in and debug services call received
by the server side php script.

In the archive I found Evert' reply (to similar problem) where he wrote:

"The problem here is, that the entire request has already completely
been handled and decoded.
So, the trick is to call registerClass before anything else.. (so
before you hit $server->exec())."

OK so I have put SabreAMF_ClassMapper::registerClass in the sequence
given below:
$server = new SabreAMF_CallbackServer();
$server->onInvokeService = 'myCallback';
SabreAMF_ClassMapper::registerClass('TestVO' ,'TestVO');
$server->exec();

But I cannot see (when debugging) any call to remapping of the
$request['data']->body which is already SabreAMF_TypedObject after
deserialization invoked in the constructor of SabreAMF_Server
class.

Variable $request['data'] has necesary information about the local ClassName
$request['data'] = (amfClassName => 'TestVO',
                    amfData => array(name => 'some name',
                                     id => 77)
                    )

Is there any built-in way to remap $request['data'] to contain TestVO object
instance that could be passed as an argument to the function?

I have tested with Eric's gateway, and then finally with modified
callback based on
http://code.google.com/p/sabreamf/wiki/CallbackServer and the rest of
the service class and VO object class files kept in the root folder of
callback - with the same result.

Hi Grzegorz,

Classmapping is done during deserialization (like you probably suspected).
I must ask the obvious questions:

  * Is the class actually included, or do you have an autoloader?
  * What is the full error message?
