ObjectGraphLinearizer is trying to deserializer instance of lively.Presentation.PageMorph but this class cannot be found

This message appears because one object that you wanted to load is an instance

of a class defined in a module that could not be loaded. In particular the

core repository does not include the module lively.Presentation (because we do

not consider this as part of the core). So this is not a problem with your

installation but you could consider it as conceptional issue of using a

"remote" PartsBin, or, going one step farther of differentiating between

"objects" and "source code" at all.

This issue didn't came up until now because usage of the PartsBin only

happened from within the Webwerkstatt environment where all dependencies are

available.

To solve this problem for now you can

1. Work in the online wiki http://lively-kernel.org/repository/webwerkstatt/

or

2. Create a working copy of webwerkstatt locally using "lk workspace

--checkout-ww" and then start the server with "lk server --lk-dir `lk

scripts-dir`/workspace/ww" (all lk-scripts commands are documented here:

https://github.com/rksm/LivelyKernel/wiki/livelykernel-scripts)

This gives you a complete copy of webwerkstatt.

or

3. Manually copy the required modules into "`lk scripts-dir`/workspace/lk"

Since we want to go towards a model of distributed Lively installations that

share object repositories like Webwerkstatt's PartsBin (as opposed to just

have the Webwerkstatt) we will work on a better and more general solution for

that problem. As of now I can just offer you the solutions above.

Hope that helps,

Robert

Hello

I am playing around with the parts in the PartsBin - on my own server - and get this error message. The version of the lively-kernel server does work. So, am I missing something from my copy of the PartsBin (seems likely), or is there an add-on to the server that I don't have in my environment?

And, related to the first question, how do I keep my copy of the PartsBin up to date? is there an svn update built into the server?

Cheers

Andy

Thanks for the options.

I tried using the --checkout-ww command. It pulled down a complete copy of the core BUT the PartsBin folder only contained a single folder called zp, which was empty.

I did a lk partsbin, and that seemed to bring down the full partsbin. However, looking at the error messages, it seems as though the core - as installed by the osx app doesn't include much in the apps directory.  I am currently shuffling things around to try to get one complete image.
