Header issue : java.lang.IllegalStateException: The specified child already has a parent. You must call removeView() on the child's parent first.

Hello, I create header view holder in such way: @Override public AisleHeaderHolder onCreateHeaderViewHolder(ViewGroup parent) { View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.listitem_aisle_header, parent, false); return new AisleHeaderHolder(view); }

and I got sometimes such a crash, any idea how to resolve it ? :
