why does saving sessions in symfony2 delete my attributes?

This question is exactly as specified as above. I have code that looks like this:

// These attributes are getting deleted for some reason
$this->session->set('userProfiles',new ArrayCollection($uniqueList));

// Get array filter and save it in session
$this->session->set('filter',$filter);

// Save session
$this->session->save();

// The code bellow effects my attributes above. I don't know why that is.
$this->session->set('center',$center);
// If I comment the line bellow then attributes 'userProfile' and 'filter' do not get deleted
$this->session->save();

I am so beyond baffled as to why $this->session->save(); after setting my center attribute is actually deleting my data. Symfony does not have anything like this documented. It might have something to do with garbage collection, but I don't really know.

Things you put in the session must be serializable. ArrayCollection does not seem to implement the \Serializable interface.

You can learn more about PHP session handling in the documentation:

When PHP shuts down, it will automatically take the contents of the $_SESSION superglobal, serialize it, and send it for storage using the session save handler.
