Fragmentation failed with Parcel: it is not possible to output a marshal error when calling the onPause method

Question

I have been developing Android apps for a long time, but only recently got it from Fragments, and therefore I have a lot of problems learning how to work with them. One of the activities in my applications consists of four different fragments, each of which displays a list of elements for the user. Each fragment is created first and is displayed only after it is selected and hidden when another tab is selected. After creating each of these fragments, an ArrayList from JSONObjects is passed as an argument to the fragment as follows

            ft = fm.beginTransaction();

            if(currentFragment !=null){
                ft.hide(currentFragment);
            }
            if(whereFragment !=null){
                ft.show(whereFragment);
            }else{
                if(mPlaceList.size()>0){

                Bundle bundle = new Bundle();
                bundle.putSerializable("array", mPlaceList);
                whereFragment = new WhereFragment();
                whereFragment.setArguments(bundle);
                ft.add(R.id.newpost_container,whereFragment, "whereFragment");
                }
            }
            ft.commit();
            currentFragment = whereFragment;

Arraialist obtained in fragment, and everything works fine.

actList = (ArrayList<JSONObject>) getArguments().getSerializable("array");
doingAdapter = new DoingAdapter(getActivity(), actList);
actListView.setAdapter(doingAdapter);

// get your data
Bundle bundle = getArguments();
JSONObject myData = (JSONObject) bundle.getSerializable("myData");

// remove it
getArguments().remove("myData");
