Server Side Actionscript (SSAS) function arguments

[PabloS]

I have a server-side actionscript function with one argument. The data type I'm sending it is a simple actionscript object:

// in flash
foo = {x: 1};
netService.test(foo);
// should return 1
// returns undefined

// on remoting server
function test(arg) {
return arg.x;
}

Theoretically this should work; flash passes whole actionscript objects to the remoting server. However, in practice, test returns undefined!

Has anyone else had this problem?
