Variable number of arguments is not supported for services error… Magento and Zend_AMF

Here is a little something to share with the world. Last night I was building a nice little application for Flex – AMF – Magento development. Basically it consists of Flex application from which you are calling Magento AMF server. AMF server is made as a module in Magento, with its own config.xml file, controller and model files. Basically I already build an application, just wanted to share interesting issue I come across. When I wish to extend any of my models with some of Magento models I get following error from AMF server: “Variable number of arguments is not supported for services (except optional parameters). Number of function arguments must currespond to actual number of arguments described in a docblock.“.

So by doing the class definition like below, Zend_AMF component will work just fine.
class MyCompany_MyModule_Model_MyModel

And doing it like

class MyCompany_MyModule_Model_MyModel extends Mage_Core_Model_Abstract

will trigger the above error.

Solution? Workaround. For most of the part you will not need to extend model class. If you do need something like that, why not store the instace of Mage_Core_Model_Abstract class in private property then work on that property within your class. I?m talking about scenarios where you need to implement Zend_Amf and Flex into Magento.
