#ViewScoped is recreated after button action on WebLogic - jsf

Question

First of all I know some other similar questions about my title, but My issue is a little bit different... When I try to initialize LazyDataModel in my #ViewScoped Bean it works fine until I click the actionButton on my page. When My Bean is created, its #PostConstruct method works as expected and LazyDataModel filled up in that method then datatable populated well. But when ajax called by actionButton in my page then entire bean recreated and #PostConstruct method called again, with that LazyDataModel value changing to null. Because of that, my page is crashing. In another scenario I was using rowSelect event in my datatable instead of actionButton with method which has a SelectEvent parameter. In SelectEvent parameter object field of it was null and I was getting NullPointerException. These are the scenarios... As result I guess when I use LazyDataModel in my #ViewScoped bean It calls PostConstruct again and my datamodel returns null for my SelectEvent method.
This is my ViewScoped PostConstruct method

When I clicked a row of Datatable selectEvent.getObject() --> NULL always with LazyDataModel.
A big important information: These all situations happens in WebLogic 10.3.6.0 and works on TomCat like charm (even with LazyDataModel).
My Development environment: JSF 2.0, Primefaces 5.2, Liferay 6.2.3 ga4 with TomCat 7.04.
Testing environment: Same all except WebLogic 10.3.6.0 (Problem only occurs on here)
I really appreciate if someone could help me... Thanks in advance!!!

}
We can access Spring Beans like that:
public EContractProcessService geteContractProcessService() {
ELContext elContext = FacesContext.getCurrentInstance().getELContext();
return (EContractProcessService) FacesContext.getCurrentInstance().getApplication()
.getELResolver().getValue(elContext, null, "eContractProcessService");
}
