Currently I working on implementing web based application with persistence to DB . I use Spring 3.2.3.RELEASE , Hibernate 3.5.6-Final , JSF 2.1.6 + PrimeFaces 3.5 .
I get org.hibernate.LazyInitializationException not a first time , before I solve it by adding FetchType.EAGER to problematic fields of bean , but this time it don't solve problem , I am suspecting that it is because collection that I try to fetch is enum . Also I try to implement org.springframework.orm.hibernate3.support.OpenSes sionInViewFilter , but it also not solve the problem or I just fail to implement it correctly .
Here is code / configs :
web.xml :
dispatcher.servlet.xml :
problematic bean :
Exception happens when I try to save entity but before i get to SchedulingSettingsManagedBean.onSave .
Could you please give me a tip how to solve it ?
