[sc-users] Hello & an archive problem

[Thorsten Stocksmeier <tstocksm@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi!

This is my first posting to sc-users. I'm very glad this list exists.

At the moment I'm having a problem archiving objects and I don't
really understand what's going wrong.

I would like to archive an object that looks like this:

Instance of SonOptParMap {    (04F1A7A0, gc=D4, fmt=00, flg=80, set=04)
  instance variables [9]
    mixture : instance of Array (04F70110, size=5, set=3)
    span : instance of Array (04F5DDA0, size=5, set=3)
    position : instance of Array (04F54310, size=5, set=3)
    scores : instance of Array (055839D0, size=3, set=2)
    duration : Integer 2
    synth : nil
    dsets : instance of Array (04F32D60, size=3, set=2)
    timeBetween : Float 0.7   3FE66666 66666666
    totalDuration : Float 7.3999999999999995   401D9999 99999999
}

I'm using writeBinaryArchive in a CocoaDialog action. The file
created is only 17 bytes long.

Contents are:

00000000  21 53 43 61 00 00 00 02  00 00 00 00 6f 00 00 00  |!SCa........o...|
00000010  00                                                |.|

When I load this object shortly afterwards with loadBinaryArchive,
the following error (understandably) appears:

ERROR: Primitive '_ReadArchive' failed.
Wrong type.

    Meta_CocoaDialog-ok   05765B50
        arg this = class CocoaDialog
        var res = [*1]

I tried using the *TextArchive functions, but they didn't do what I
thought they did either (not mentioning the system crashes where sc
hogged the whole OS)

When I use the *BinaryArchive functions on something easier like a
Point object, it is correctly serialized and unserialized later.

So at the moment I'm pretty confused how I can load and save my
object with its contents to and from disk. Any ideas what's going
wrong here?

Thanks in advance,
Thorsten
