Not everything can be stored in the session. Especially object references (as they are valid only in the same process). You can put in a "WebForm variable" (i.e. Me[xxx]) : booleans, numbers, strings, dates, variant, arrays and collections. I hope I will be able to start writing the documentation of the gb.web.form component soon.
