Andres,
Your problems are actually two-fold, I believe.
The first is that SimpleXMLEncoder and SimpleXMLDecoder do not appear to be
symmetrical with Array properties.
If your object has a property
var arrayProperty:Array
The SimpleXMLEncoder writes
<arrayProperty>
<item>val1</item>
<item>val2</item>
<property>
But when SimpleXMLDecoder decodes this XML it produces an object with
arrayProperty = { item: [val1, val2] }
This is becase SimpleXMLDecoder tries to be "smart" and sees the two <item>
tags and decides that the implied array you want is actually a property
called "item".
I regard this as a bug in Flex 3 - encode/decode should be symmetrical.
Your second problem is that you can't just cast an arbitrary object to being
of a specified type. Whether the fields line up or not doesn't matter: you
simply can't cast this way.
