[Seaside / Magma] lost of session?

[florent trolat]

When I try to get an object from the magma database to my system I 
connot, after that, access to my seaside application.
I obtain :
"Request handling aborted; reload to retry"

I 've inspect: I get a right object, but the seaside application seems 
to be lost.

Someone can give me an idea to solve that?

thank.

PS: I've read that Seaside must use WAMagmaSession... I have not this 
class, it's a problem?
