I have a method with the following structure:
public void run(){
...
for (...) { //this part works correct
User.withTransaction {
User user = User.findByUsername(...);
Position pos = Position.findByName(...)
if(pos){ ...
} else { ...
try{
pos.save(flush:true);
user.position = pos;
} catch (Exception e){ ... }
}
...
try{
user.save(flush:true, failOnError: true);
} catch (Exception e){ ... }
}
}
//this part doesn't work
User.findAll().each {
...
if (...){
User.withTransaction{
...
//here the operation fails with
//org.hibernate.LazyInitializationException:
//could not initialize proxy - no Session
if (!userDetailsMap.containsKey(it.username)
&& it.userStatus != blocked){
it.userStatus = blocked
it.save(flush:true)
}
}
}
}
}
The exception I'm getting here is org.hibernate.LazyInitializationException: could not initialize proxy - no Session
in the second part of my code. Here the userStatus
field is a reference to a different domain class.
I tried to add it.refresh()
and Hibernate.initialize(it)
to the code before properties are checked, but no use. What am I doing wrong here?
upd: I tried to call the it.attach
method before the properties are checked, but right after the method call the value of it.attached
is false
.
I don't think you are doing anything 'wrong', it is just that the object got detached from the hibernate session. A couple of things I'd try:
