VBScript OCX receive and supply a safeArray of type VT_UI1- problem

Hello all,

I've just build an OCX for usage within vbscript, and am running into a 
problem :

I'm trying to have a method #1 return a SafeArray of type VT_UI1, and later 
provide it to a method #2.

The problem is that when I do this :

Object.Method2(Object.Method1())

everything works.

But when I use an intermediate variable like this

Data = Object.Method1()
Object.Method2(Data)

VBScript throws a "Type mismatch" error - and I have no idea why or how to 
solve it. :-(

Declarations of both methods in the IDL file :

HRESULT Method1([out, retval] SAFEARRAY(unsigned char)* Result);
HRESULT Method2([in] SAFEARRAY(unsigned char) ByteData);

By the way:

wscript.echo vartype(Object.Method1())
Data = Object.Method1()
wscript.echo vartype(Data)

both of the above return &H2011 (array of VT_UI1)

Help ?

Regards,
