I'm trying to do the same... ReferenceStream doesn't work because it
encounters a BlockContext in the process (eg. some Magritte condition
on the number of posts the blog should show).

I'm trying to go the Magma way but it won't install' either via
Universes or MC. Magma seaside says it needs WADispatcherControlPanel
(I'm following the load order from http://wiki.squeak.org/squeak/5902
)

Any suggestion ?

Re: Extracting a pier root

I'm using SIXX to move a site from one image to another.

HTH,
Adriaan.

Thanks for the suggestion. Are you doing something particular?
SIXX (latest from squeakmap) doesn't load in my 3.10 image...

Re: Extracting a pier root

My bad, didn't see it in the universes browser.

Re: Extracting a pier root

Haven't tried anything with 3.10. I'm using SIXX 0.2c with 2.9.

wow :)

So serializing the kernel out to a file worked directly, but when
loading the .sixx file back in another image, it tries to put a nil
inside a set, and the set complains. What could replace some object by
a nil like that? unserializable object on one end, or missing classes
in the new image?
I think I have the same classes available, but it's late, I will check later…

Anyway, thanks

This sounds like the Set is not properly hashed. Probably due to a bug  
in the SIXX Set serialization.

Cheers,

It would be really cool if we could get that working.

I find SIXX very interesting because it would potentially allow to  
exchange Pier instances between the different Smalltalk dialects:  
Squeak, GemStone and VisualWorks.

Cheers,
Lukas

These snippets run fine on an out-of-the box Pier from Seaside.530

| stream |
stream := ReferenceStream fileNamed: 'export.obj'.
stream nextPut: (PRKernel instanceNamed: 'Pier') root sixxString.
stream close.

| stream |
stream := ReferenceStream fileNamed: 'export.obj'.
(PRKernel instanceNamed: 'Pier') root: (Object readSixxFrom: stream  
next).
stream close.

Why use a ReferenceStream to store XML in a file?

> So, what is that is not working?

I'm not sure… I installed a few add-ons and use Pier-Security.
Those refer to classes from the objects inside the PRKernel (so
serializing with a ReferenceStream would end up serializing the whole
class hierarchy. Also, as I said, some objects store BlockContexts
from Magritte conditions, and it seems ReferenceStream doesn't want to
serialize these.

I'm not really clear why SIXX would know better about how to serialize
stuff than ReferenceStream…
