And this is the argument which is passed to the "set data"-field implementation:
<type name="Object" isDynamic="true" isFinal="false" isStatic="false">
<method name="hasOwnProperty" declaredBy="Object" returnType="Boolean"
uri="http://adobe.com/AS3/2006/builtin";>
<parameter index="1" type="*" optional="true"/>
</method>
<method name="isPrototypeOf" declaredBy="Object" returnType="Boolean"
uri="http://adobe.com/AS3/2006/builtin";>
<parameter index="1" type="*" optional="true"/>
</method>
<method name="propertyIsEnumerable" declaredBy="Object" returnType="Boolean"
uri="http://adobe.com/AS3/2006/builtin";>
<parameter index="1" type="*" optional="true"/>
</method>
</type>
Any input would be thankfull!
