I guess you are trying to put an object into wddx

Hello Luis,
Thanks for the response... Here is the deal I have been working on a
big project using coldbox as a framework. It was ready to be released
until I start getting an error when one of our severs died. I realized
I was not using client variables instead I was using session variables
(sessionstorage). I read the docs and found there was I plugin called
clientstorage. I started replacing sessionstorage with clientstorage
in all my code and then I got the above error. Now I understand I can
not store my beans(objects) on the clientstorage.

So i have this is my code:
getPlugin("sessionstorage").setVar("oUserBean",userBean);

I can not do this
getPlugin("clientstorage").setVar("oUserBean",userBean);

So how can I manage sessions on multiple servers? How can I keep my
beans in both servers. Any advise?

If you are on Railo or cf9, you could potentially store objects in client scope by serializing them. But you have to be concerned with the object graph of such objects so you don’t serialize every single component relationship.

You can use the objectLoad() and objectSave() methods to serialize components or use the ColdBox utilities plugin for this, which abstracts the engine you are using. Just note that serialization and deserialization take time, so I would be very careful on this. Maybe do a session + client strategy where the object lives in session and have a low expiration time out. If it expires, go to client to inflate it back into session and so forth.
