The line that throws the exception is below:
CheckBoxMultipleChoice subMessagesCB = new CheckBoxMultipleChoice(
"subMessages", new PropertyModel(this,
"selectedSubs"), showMessage.getLazyList());
The problem is the showMessage.getLazyList() call. When wicket renders
this combobox, spring filter have already closed the EntityManager.
If I uncomment this line (ugly hack):
//showMessage.getLazyList().size();
Everything works.
I am using tomcat 6.0.18 (bundled with Netbeans).
The stacktrace:
ERROR - azyInitializationException - failed to lazily initialize a
collection of role: com.mycompany.persistence.domain.Message.lazyList,
no session or session was closed
