[Flow] Multi step form - save values in session

[Alexander Berl]

Hi Mark,

the session works by serialization/unserialization of the data, so for
it to work properly you need to make sure that the Object you want to
store can be properly serialized and unserialized, ie.
[igbinary_]unserialize([igbinary_]serialize($data)) == $data

I'm not sure how it would be possible that get_class($member) returns a
class name but the content of $member would be an array, so maybe I'm
getting something wrong.
I would rather suspect there is some small logic error in your code
somewhere, for example that the session data gets overwritten with array
data somewhere.

As to the propertyMapping, you are most likely just missing a proper
PropertyMappingConfiguration for all subproperties (assuming the
propertyMapper is properly injected and hence initialized and
is_array($session->getData('member')) is TRUE).

Here would be a good point to provide more information in form of full
code of your model and the dump output after retrieval from the session
and (if still relevant) after the property mapping.

Regards,
Alexander
